Using TV Out 29  
CHAPTER 6:  
Using TV Display and Capture Features  
This chapter describes how to use the TV display and video capture  
features of your Radeon® X1950 XTX card.  
Using TV Out  
Your Radeon® X1950 XTX has TV Out capability.  
Viewing Your PC’s Display on a TV  
You can attach your Radeon® X1950 XTX to a TV and a monitor at the  
same time.  
Note: A TV can only be connected to one DVI connector.  
IMPORTANT INFORMATION for European Customers  
L
Some PC monitors in Europe cannot be used simultaneously with TV  
display. When you enable TV display in Europe, the refresh rate for the  
monitor and TV is set to 50 Hz. Some monitors may not support this  
refresh rate and could be damaged.  
Please check the documentation supplied with your monitor to see if  
your monitor supports a refresh rate of 50 Hz.  
If your monitor does not support 50 Hz (or if you are not sure), turn off  
your monitor before turning on your PC when using your TV as a  
display.  
TV display is ideal for giving presentations and watching movies, or  
playing games on a screen larger than a typical monitor. The following tips  
will help you get the most out of your TV Out feature.  
Connecting to a TV  
Your Radeon® X1950 XTX card transmits HDCP compliant signals to  
digital TVs.  
To use a DVI connection  
1
Determine if your TVsupports DVI. If it does not, you will need a  
DVI adapter for the video signal.

Using a Monitor vs. Using TV Display  
Using your TV for your computer’s display can be useful, however, the  
display on your monitor may change or looked squashed. This distortion  
occurs because the display adjusts to fit the dimensions of your TV. To  
correct the monitor’s display, use the monitor’s control buttons to adjust its  
display size and position.

Connecting to HDTV 31  
Some single-frequency monitors may not work with TV display enabled. If  
you experience problems when TV display is enabled, disable TV display  
to restore your monitor’s display.  
Viewing Text on a TV  
A TV is designed primarily to show moving images. The large dot pitch of  
a TV will yield poor quality static images. The small text sizes commonly  
used for PC desktops can appear blurred or unclear on a TV. You can  
compensate for this degradation by using larger fonts.  
Using a TV as the Only Display  
If you plan to move your computer to a place where you are using TV  
display only, make sure that you have the TV display feature enabled prior  
to removing the monitor.  
The maximum display resolution for TV is 1024 x 768. Choosing a  
resolution higher than this will cause the TV display to disappear if it is the  
only display device.  
Using Games and Applications  
Some older games and applications may program your Radeon® X1950  
XTX directly to run under a specific display mode. This may cause your  
TV display to turn off automatically or become scrambled (your PC  
monitor or portable LCD display will not be affected). Your TV display  
will be restored once you exit the game or if you restart your computer.  
Connecting to HDTV  
View computer output directly on your High Definition Television  
(HDTV) or other component input device. Provide a big-screen experience  
for your computer that is ideal for playing games, giving presentations,  
watching movies, and browsing the Internet.  
HDTV uses YPbPr connectors to receive input. YPbPr stands for the  
following:  
• Y = Green  
• Pb = Blue  
• Pr = Red

32 Connecting to HDTV  
The HDTV Component Video Adapter can be used in place of the standard  
A/V Output cable to connect to an HDTV or other component input device,  
using component video cables.  
You must have a monitor attached to your computer before installing  
the ATI HDTV. For proper operation of your ATI Component Video  
Adapter, ATI display drivers must be correctly installed.

CrossFireOverview 35  
CHAPTER 7:  
Using the Radeon® X1950 XTX  
with CrossFire™  
The Radeon® X1950 XTX can be used as a Slave graphics card in a  
CrossFiresystem.  
For the full system requirements necessary to put together a working  
CrossFiresystem, see the CrossFireFAQ.  
CrossFireOverview  
This section provides an overview of the main features and configurations  
for CrossFire. These topics will be covered in more detail in other chapters  
of this manual.  
Allowable CrossFireSystem Components  
The basic requirements of a CrossFiresystem are a CrossFirecertified  
motherboard with two PCI Express® x16 slots, a CrossFireEdition  
graphics card, and a compatible CrossFireCompatible graphics card.  
A CrossFireEdition graphics card works with all members of the same  
brand-family. Thus a CrossFireEdition graphics card can be used with  
any Radeon® X1950 product.  
For an up-to-date listing of CrossFirecertified motherboards, see:  
CrossFireRendering Modes  
A CrossFiresystem has four possible display modes:  
• SuperTiling  
• Scissor Mode  
• Alternate Frame Rendering  
• Super Anti-aliasing.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
                       
36 CrossFireRendering Modes  
The first three are performance-oriented modes, while Super Anti-aliasing  
is a quality-oriented mode. Each mode uses a different method for dividing  
the workload required to render a 3D image across multiple GPUs. Only  
one mode can be in operation at any given time.  
The ATI Catalystdisplay driver will automatically select the best of the  
three performance modes when a 3D application is started, without  
requiring user intervention. The user can also choose to improve image  
quality by selecting the new Super Anti-aliasing modes in the Catalyst™  
Control Center.  
SuperTiling  
In this mode, each frame to be rendered is divided into a number of tiles in  
an alternating checkerboard pattern, so that half of the tiles are assigned to  
each of the two GPUs. Each tile is kept to a relatively small 32x32 pixel  
square, so this method does a good job of balancing the workload across  
each GPU regardless of what is being rendered on the display, doing so  
without any software overhead.

SuperTiling has the advantage of being able to work with practically any  
3D application. However, there are a small number of applications where  
the SuperTiling workload distribution does not provide optimal  
performance. For these special cases, Scissor Mode can be used.  
Scissor Mode  
In this mode, each frame is split into two sections, with each section being  
processed by one GPU. The ideal configuration is determined  
automatically for each application.

Although Scissor Mode is generally a less efficient means of splitting the  
workload than using SuperTiling, there are a few cases where it can be  
more efficient. It is supported by CrossFirein order to maximize  
compatibility and performance.  
Alternate Frame Rendering (AFR) Mode  
In this mode, all even frames are rendered on one GPU, while all odd  
frames are rendered on the other. The completed frames from both GPUs  
are sent to the Compositing Engine on the CrossFireEdition card, which  
then sends them on to the display. By allowing both GPUs to work  
independently, AFR provides the greatest potential performance  
improvements of all the available modes. It is also the only mode that  
allows the full vertex processing performance of both GPUs to be  
combined.

The main limitation of this mode is that it cannot be used in applications  
where the appearance of the current frame is dependent upon data  
generated in previous frames, since AFR generates successive frames  
simultaneously on different GPUs. In these cases, the SuperTiling or  
Scissor Mode is used instead.  
Super Anti-aliasing Mode  
Anti-aliasing (AA) is a rendering technique designed to remove jagged  
edges, shimmering, and pixelation problems that are common in rendered  
3D images. Rather than simply determining the color of each pixel on the  
screen by sampling a single location at the pixel’s center, anti-aliasing  
works by sampling multiple locations within each pixel and blending the  
results together to determine the final color.  
The latest generation of ATI’s Radeon® GPUs with SmoothVisionHD  
technology uses a method known as Multi-sample Anti-aliasing (MSAA).  
This method takes samples from 2, 4, or 6 programmable locations within  
each pixel, and uses gamma correct sample blending for high-quality  
smoothing of polygon edges. The new CrossFire Super Anti-aliasing mode  
takes advantage of the programmable sample capability of SmoothVision™  
HD to provide higher quality anti-aliasing on CrossFiresystems.  
It works by having each GPU render the same frame with anti-aliasing  
enabled, but uses different sample locations for each. When both versions  
of the frame are completed, they are blended in the CrossFire Compositing  
engine. The resulting image has effectively twice the number of samples,  
so 4x and 6x Anti-aliasing becomes 8x and 12x Super Anti-aliasing,  
respectively.

Some types of textures, especially those with transparent portions, can  
exhibit aliasing that is not removed by MSAA techniques. Another form of  
anti-aliasing, known as Super-sample Anti-aliasing (SSAA), can be useful  
in these cases, because it affects every pixel in an image. Although it  
normally operates more slowly than MSAA, the power of multiple GPUs  
can make SSAA practical to use.  
SSAA first renders a scene at a higher resolution than that which is output  
to the display, which is then downsampled to the display’s resolution. This  
approach normally has two main disadvantages: it requires rendering many  
more pixels than normal, which can have a drastic impact on performance,  
and that it results in an ordered grid sample pattern, which does a poor job  
of anti-aliasing some types of jagged edges. CrossFire’s Super Anti-  
aliasing overcomes both of these problems. It takes advantage of the second  
GPU to render the additional pixels required for each frame, so there is little  
or no performance impact. It can also make use of a more effective sample

Super Anti-aliasing Mode 41  
pattern that does a better job of anti-aliasing near-horizontal and near-  
vertical edges, resulting in better overall image quality.  
Two of the new Super Anti-aliasing modes use a combination of MSAA  
and SSAA to achieve the ultimate in image quality. They work by not only  
using different multi-sample locations on each GPU, but also by offsetting  
the pixel centers slightly. In effect, each GPU renders the image from a  
different viewpoint, about half a pixel width apart. The new 10x and 14x  
Super Anti-aliasing modes operate in this manner, combining 2x SSAA  
with 4x and 6x MSAA, respectively.  
Both of these modes work together with SmoothVisionHD Anisotropic  
Filtering (AF).  
The new Super Anti-aliasing modes can be enabled by users through the  
ATI CatalystControl Center interface.  
Note: Enabling the Super Anti-aliasing modes (x8, x10, x12 x14),  
disables performance enhancing multi-GPU rendering to provide  
better image quality.

CHAPTER 8:  
CrossFireFAQ  
The following are frequently-asked questions about CrossFire.  
For the latest information, please consult the CrossFireWeb site at:  
1
What combination of products are required to build a working  
CrossFiresystem?  
Three components are required:  
• a CrossFireEdition graphics card that works as the Master  
graphics card.  
• a CrossFireReady graphics card from the same brand-family  
that works as the Slave graphics card.  
• a CrossFireReady motherboard (which contains two PCIe™  
X16 slots).  
More information on the requirements for each of these components  
can be found within this FAQ.  
2
What graphics cards work with CrossFire?  
A CrossFiregraphics card works with all members of the same  
brand-family. Thus a Radeon® X1800 CrossFireEdition can be used  
as the Master graphics card with any member of the Radeon® X1800  
family.  
3
4
What motherboards support CrossFire?  
Any certified CrossFiremotherboards based on Intel® and ATI  
chipsets.  
Are there specific CMOS motherboard settings for CrossFire?  
On some motherboards, the CMOS may be set by default to support  
only a single PCI Express® X16 slot. Ensure that both PCIeX16  
slots are enabled in the CMOS.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
               
44  
5
Which slot does the CrossFireMaster card go into on the  
motherboard?  
The CrossFireMaster card must go into the primary PCI Express®  
slot (slot zero) on the motherboard.  
Note: To determine which PCIeslot is the primary slot, consult  
your motherboard manual.  
Alternately, to determine whether or not a CrossFireEdition card is  
in the correct slot, connect your display directly to the DVI-I  
connection on the Master graphics card instead of using the  
CrossFireconnector, with both graphics cards seated in their  
respective slots on the motherboard. If an image appears on the screen  
upon boot-up, the card has been placed in the correct slot on the  
motherboard.  
6
Are there any software settings required for CrossFireto work?  
Yes, there is a setting in the CatalystControl Center that needs to be  
enabled for CrossFireto operate. When all of the hardware and  
software has been properly set up and installed, the following  
CrossFireaspect appears in CatalystControl Center:  
Download from Www.Somanuals.com. All Manuals Search And Download.

To access and enable CrossFirein CatalystControl Center, do the  
following:  
• Click CrossFirein Advanced View. Then, select Enable  
CrossFire.  
When CrossFireis successfully enabled, all display devices except  
the one used by CrossFirewill be disabled. Multiple monitors/  
displays that are disabled when CrossFireis enabled reappear after  
CrossFireis disabled.  
To change to Advanced View:  
• Click the Dashboard View button and select Advanced View.  
• Select Displays Manager in the tree view.  
7
What is the difference between a CrossFireEdition graphics  
card and a standard graphics card from the same family?  
CrossFireEdition graphics cards include a “compositing engine”, a  
chip that takes the partially rendered image from the Slave graphics  
card and merges it with the partially rendered image from the Master  
Download from Www.Somanuals.com. All Manuals Search And Download.  
           
46  
graphics card. The result is a complete frame rendered at up to twice  
the performance of a single graphics card.  
8
9
How are the graphics cards connected on a CrossFiresystem?  
The two cards are connected by an external cable. The cable is  
attached from the Slave graphics card’s DVI-I connection to the  
CrossFireEdition’s CrossFireconnection, which is used to convey  
information from the Slave graphics card to the Master graphics card  
and transmit the combined signal to a display device.  
Which games/applications work with CrossFire?  
CrossFireworks with all full-screen 3D games and applications.  
CatalystA.I. is enabled by default in the CatalystControl Center  
software. This automatically selects the optimal rendering mode for  
the application.  
10 Is a driver profile required to make CrossFirework?  
No. CrossFireis enabled by default for all full-screen 3D games and  
applications.  
11 What happens if you pair a two CrossFireEdition graphics  
cards with different architectures?  
In this scenario both graphics cards will operate at the speed of the  
slower graphics cards while in CrossFiremode. You will be required  
to restart your computer for this matching to take place.  
12 What happens if the CrossFireEdition graphics card and the  
CrossFireReady graphics card have different clock speeds?  
Both cards will continue to operate at their individual clock speeds;  
neither card is “stepped down.” The compositing engine on the  
CrossFireEdition card merges the resulting images independent of  
the clock speed on either graphics card.  
13 On what basis are different rendering modes chosen?  
When CatalystA.I. is enabled in CatalystControl Center, it  
determines the optimal rendering mode to use, based on the  
application or game being used. The default rendering mode is  
dependant on both the hardware configuration and the application  
being run.  
14 What type of performance improvement is expected?  
Performance enhancements experienced on a CrossFiresystem  
depend on the application or game being used. Performance  
improvements can be increased up to 100%.

47  
15 How many independent displays can be connected to a  
CrossFiresystem?  
While CrossFireis designed for optimal use on a single display, it is  
possible to drive multiple monitors using a CrossFiresystem when  
CrossFireis not enabled. If the motherboard contains an integrated  
video connection and SurroundViewis enabled, more displays can  
be added. However, when CrossFireis enabled all display devices  
connected to both CrossFiregraphics card will be disabled except  
the one connected to the CrossFireconnector.

Troubleshooting 51  
CrossFire-Specific Troubleshooting  
Problem  
Possible Solution  
CrossFireis Not  
Functioning  
In order for CrossFireto function the interconnect cable  
must be correctly connected to both the Master and Slave  
graphics cards.  
1. Connect the DMS-59™ connector of the interconnect  
cable to the DMS-59™ connection on the Master card.  
2. Connect the DVI-I connector of the interconnect cable  
to the DVI-I connection on the Slave card.  
3. Connect the remaining DVI-I connector of the  
interconnect cable to your monitor.  
On graphics cards with two DVI-I connectors, only one  
DVI-I connector on the Slave card supports Transition  
Minimized Differential Signaling (TMDS) required by  
CrossFire. If CrossFiredoes not appear in the Catalyst™  
Control Center or is not available, try connecting to the  
second DVI-I connector on the Slave card.  
You will not be able to start CrossFireif a 3D application,  
game, or video playback, such as a DVD movie, is  
running.  
“Before  
CrossFirecan  
be enabled, you  
need to close the  
3D application or  
video playback

CHAPTER 10:  
Glossary  
2D  
Acronym for “two dimensional,” a term applied to computer graphics that  
are “flat.” Typical desktop applications such as word processors,  
spreadsheet programs, or other programs that manipulate print or simple  
graphics (such as pictures or line art) are generally considered to be  
operating within a 2D environment, even when they include simple three  
dimensional elements, such as buttons.  
Pulldown  
Pulldown is a telecine technique used to transfer motion picture film shot  
at one frame rate to a video format at a different frame rate. Typical NTSC  
video contains more frames per second than motion picture film for even  
division between frames, so that every 4 frames of film can be reproduced  
as 5 separate NTSC frames, the “extra frame” created by interlacing  
interpolated frames. The features produces a smoother NTSC video image  
from a motion picture film source, and can be used for better edge image  
processing in the Vector Adaptive Deinterlacing feature within Catalyst™  
Control Center.  
3D  
Acronym for “three dimensional,” referring to computer graphics that  
appear to have volume and depth. Various modeling processes take the  
representation of a three dimensional object provided by the computer  
program and render it by using various lighting components, applying  
textures, and setting layers of transparency or opacity as required in order  
to produce a realistic representation of a three-dimensional object on a two-  
dimensional display.  
3Dc™  
An ATI hardware-based compression technology that reduces the size of  
3D texture data, rendering more finely-grained texture surfaces with  
greater efficiency. It significantly minimizes the memory footprint of  
normal maps containing information on how light reflects off textured  
Download from Www.Somanuals.com. All Manuals Search And Download.  
                 
60  
surfaces, allowing game programmers to include more texture and lighting  
details without affecting performance.  
Adaptive Anti-aliasing  
Adaptive anti-aliasing is a technique that applies a combination of multi-  
sampling (MSAA) and super-sampling (SSAA) on 3D objects to improve  
edge smoothness and fine detail. Multi-sampling works best on smoothing  
the edges of solid polygons, but cannot effectively smooth edges within  
polygons which are partially transparent. Super-sampling is able to more  
accurately calculate color values adjacent to transparent pixel shader values  
within polygons with partially transparent textures, but is not applied  
universally since it is more processor-intensive. Adaptive anti-aliasing  
works by using super-sampled anti-aliasing on transparent textures, and  
multi-sampled anti-aliasing on all other textures. This delivers exceptional  
levels of image quality, while maintaining performance.  
AGP  
The Accelerated Graphics Port (AGP) is a slot on the computer  
motherboard designed specifically for 3D graphics cards. AGP runs 3D  
images much more smoothly and quickly than was previously possible with  
PCI video cards; AGP runs at several times the bus speed of PCI and  
employs sideband addressing, so multiple data transfers between the  
graphics processor and the computer can take place concurrently. AGP is  
currently being phased out in favor of PCI Express® (PCIe).  
Alpha Blending  
Alpha blending is used in 3D graphics to create transparent or opaque  
effects for surfaces such as glass and water. Alpha is a transparency value,  
so the lower the value, the more transparent the image looks. It is also used  
in animations to produce such things as fading effects, where one image  
gradually fades into another.  
Alternate Frame Rendering  
A graphical load-balancing scheme where two graphics cards are used to  
render alternate frames of the display. This configuration increases the  
detail of the 3D objects each card can render, as each card handles half of  
the total number of frames. Essentially, each card has more time to render  
a scene, delivering a noticeable increase in 3D detail. This type of graphical

operation is only available in Radeon® CrossFiregraphics cards running  
Microsoft® Direct 3D® and OpenGL® games or applications.  
Anisotropic Filtering  
A technique that preserves the surface details of an object as it recedes into  
the distance by utilizing and blending together the object’s texture maps.  
This makes 3D objects appear more realistic as the detail of their surface  
texture is retained in a smooth, seamless fashion on the sections that move  
or fade away into the background.  
Anti-aliasing  
A method that smooths out the jagged edges of a curved object. A black  
curved line on a white background displayed on a computer screen will  
have some jaggedness along its edges due to the inherent limitations of  
using discrete pixels to display the image. Anti-aliasing smooths out this  
jaggedness by filling in the white spaces between the jagged edges with  
varying shades of grey.  
Aspect  
A group of related features in ATI’s CatalystControl Center software. For  
example, the Color aspect clusters together controls that handles gamma,  
brightness, contrast, and other features relating directly to the display of  
color. Similarly, the 3D aspect provides a set of related controls dealing  
with such features as anti-aliasing, anisotropic filtering, mipmap details  
levels, and more.  
Aspect Ratio  
The proportions of a display are expressed as a ratio of its width and height.  
Common ratios include 4:3 for TVs and CRTs, 5:4 for LCDs, and 16:9 for  
widescreen displays.  
Avivo™ Color  
Avivo™ Color is an advanced feature within CatalystControl Center,  
providing the user with precise control over how color is displayed on a  
monitor. Avivo™ Color provides tools to adjust the Hue and Saturation  
values on a per-monitor basis, making it possible to optimize the use of a

62  
single display within its existing ambient lighting environment, or to better  
color match two or more adjacent monitors.  
Back Buffer  
A type of offscreen memory used to provide smooth video and 2D graphics  
acceleration. This technique uses two frame buffers, so the process is often  
referred to as “double-buffering.” While the contents of one buffer are  
displayed, a second buffer, called the “back” buffer, holds the frame being  
worked on. In this way, users will only see complete, smooth frames  
displayed onscreen.  
Bilinear Filtering  
This filtering method reduces the blockiness caused when zooming into a  
3D surface that is at a right angle to the viewer. A newspaper photo  
examined closely enough will show that the picture is made up of tiny dots.  
If the photo was enlarged it would start to look “blocky” and less distinct.  
This is also a problem for computer-generated images, especially for  
surface details.  
Bit Depth  
Refers to the number of data bits required to store color information about  
a pixel. Larger bit depth means a greater range of color information is  
capable of being encoded into each pixel. For example, 1 binary bit of  
memory can only encode to either “0” or “1.” So a graphical bit depth of 1  
means that the display can only show two colors, the black and white of a  
monochrome display. Four-bit color depth is capable of displaying 16  
colors because there are only 16 different combinations of 4 bits (“0000”,  
“0001”, “0010”... to “1111”). Sixteen-bit color is capable of reproducing  
65,536 colors, 24-bit color can display up to 16,777,216 individual colors,  
and 30-bit color can display up to one billion individual colors.  
Bitmap  
A bitmap is a graphic or character representation composed of individual  
pixels, arranged horizontally in rows. A monochrome bitmap uses one bit  
per pixel (bpp). Color bitmaps may use up to 32bpp, depending on the color  
depth selected.

63  
Brightness  
The amount of white or black that is applied to all colors onscreen. By  
making the screen “brighter” you are adding more white to it. This should  
not be confused with luminosity, which measures the actual light level  
emitted from the computer display.  
Buffer  
A name referring to portions of on-board video memory. One large buffer  
is always used to display images to the screen; this is the “display buffer.”  
The rest of offscreen memory is typically used by applications as back  
buffers, z-buffers, and texture buffers.  
CatalystControl Center  
CatalystControl Center is the successor technology to the Catalyst™  
software formerly available only through the Windows® Control Panel. It  
has a new user interface, providing a more interactive means of controlling  
such things as 2D and 3D performance while providing immediate  
feedback using a more intuitive graphical user interface.  
Color Component  
Three color components—Red, Green, and Blue—combine in various  
intensities to determine the color of each pixel on the screen. The values of  
each color component are graphically represented by a corresponding color  
curve.  
Color Correction  
Correct discrepancies between the real color value and the way a screen  
displays it. Color discrepancies can be caused by a variety of sources,  
including the lighting conditions in the work area and gradual shifts in color  
over time on monitors or flat panel displays.  
Color Depth  
Color depth refers to the number of color shades available on your display  
and is measured in bits per pixel (bpp). Typical ranges are: 256 colors  
(8bpp), thousands of colors (16bpp), and millions of colors (32bpp).

64  
Component Video  
Typically used on DVD players and HDTV systems, component video is a  
standard Red/Green/Blue (RGB) color signal for televisions. The signal is  
split and compressed into separate luminance and color values—luminance  
(“Y”), red minus luminance (R-Y), and blue minus luminance (B-Y). The  
value for green is not transmitted. The display device automatically “fills  
in” the color values that are not red or blue. DVDs are encoded using  
component video, so display devices will provide enhanced playback when  
this type of connection is used. A common variant of this format used in  
North America is YPbPr.  
Composite Video  
Composite video is a type of analog video signal that combines both  
brightness and color information into a single signal. It typically uses a  
single RCA connection for the video channel, and separate RCA  
connections for the left and right audio channels. The quality of the video  
signal is reduced by the process of mixing the brightness and multiple color  
channels together into a single channel. For this reason it is inferior in  
signal quality than either S-Video or component video. Composite video is  
the broadcast format for analog television signals worldwide, and  
connections are typically available on VCRs, DVD players and video  
games.  
Compositing Engine  
A chip that is available only on CrossFireEdition graphics cards. This  
chip takes the signals from the GPUs on both the Master graphics card and  
the Slave graphics card and combines the results according to the selected  
operating mode. It then sends the final frames out to the display device. It  
is capable of advanced blending operations without burdening either of the  
GPUs.  
Control Point  
A control point is a user-created point on the color curve. Users can change  
the color of the screen by moving the control points with a mouse.  
CRT  
Acronym for “cathode ray tube”, which is the main component of computer  
monitors and TVs. Color CRTs use three separate electron beams fired  
through a shadow mask and onto the back of the glass screen. The electron

65  
beams activate separate red, green, and blue values in various strengths in  
order to produce a colored image.  
Dashboard  
The dashboard is the part of the CatalystControl Center used to display a  
graphical representation of the features available in installed ATI hardware  
and software. The dashboard can be used to access all of the aspects (sets  
of related graphical features) available on a graphics card. The dashboard  
is only available in Advanced view and Custom view which is aimed at  
more experienced users.  
Direct 3D®  
Part of Microsoft®’s DirectX API designed for rendering 3D graphics on  
Windows® systems. It provides software developers with low-level access  
to functions on graphics cards, providing the type of performance  
necessary for intensive 3D applications such as games.  
DirectX  
A Microsoft® technology, DirectX is an API that provides programmers  
with direct access to low-level hardware functions for games and other  
high-performance 3D applications.  
Dithering  
A computer graphics technique that takes advantage of the human eye’s  
tendency to mix two colors that are adjacent to each other to produce  
smooth boundary transitions. Dithering adds intermediate color values  
between two or more boundaries, producing smoother, more natural look  
to 2D images or 3D objects.  
Dot pitch  
Dot pitch specifies the sharpness of a monitor’s display. It is measured in  
millimeters (mm) and is the distance between the individual phosphor sub-  
pixels in a CRT display or cells of the same color within an LCD display.  
The smaller the number, the sharper the image. The most common dot  
pitches for monitors range from .24 mm to .31 mm. Also, if a monitor with  
a .24 mm dot pitch is set to its highest possible resolution, the pixel size will  
equal the dot pitch. If the monitor is set to lower resolutions, the pixels will  
be comprised of multiple dots.

66  
DVI  
Acronym for “Digital Video Interface,” a standard video connection used  
on many current computer displays. There are three types of DVI  
connections: DVI-A (analog), DVI-D (digital), and DVI-I (integrated,  
capable of either analog or digital). It supports high-bandwidth video  
signals over 160 Hz, so it is most often used for high-resolution displays.  
EDTV  
Acronym for “Enhanced Definition Television”, which produces better  
television image quality than Standard Definition Television (SDTV).  
Applicable to the NTSC broadcast format, EDTV displays are capable of  
depicting the standard 480 horizontal scan lines in a non-interlaced format.  
Instead it paints all of the scan lines in one pass, which is called progressive  
scanning, a process which also removes the “jaggies” inherent in the  
interlaced television signals.  
Flat Shading  
A lighting technique that shades each polygon of a 3D object based on  
where the source of the light is and the angle of the polygon in relation to  
it. It enables relatively fast rendering of 3D objects, although it can make  
those objects appear “faceted” as each visible polygon is set to a particular  
color value, and consequently does not produce as realistic an effect as  
obtained when using Gouraud shading.  
Fog  
Term used to describe the blending of an object using a fixed color as  
objects are made to appear more distant from the viewer.  
Frame Buffer  
The portion of the memory buffer on the graphics card used to store the  
image being displayed. All rendering processes have been accomplished by  
this stage and this buffer contains only a one-to-one relationship of the data  
to be relayed to the display.

67  
Frames Per Second  
In terms of 3D graphics, refers to the rate at which the graphic processor  
can render new screens per second. Higher rates equals better, more  
naturalistic performance for such things as games set in a 3D environment.  
Sometimes abbreviated to “fps.”  
Gamma  
Sometimes confused with brightness, gamma actually refers to the  
correction that is applied to any display device in order to produce more  
gradual increases or decreases in the perceived brightness for that device.  
A change in gamma produces a non-linear change in the color curve,  
ensuring that perceived changes in color and intensity are consistently  
applied.  
Gouraud Shading  
A shading method used to produce a smooth lighting effect across a 3D  
object. A specific color is used at each vertex of a triangle or polygon and  
interpolated across the entire face.  
HDCP  
HDCP is an acronym for “High-Bandwidth Digital Copy Protection.” It is  
a form of digital rights management designed to protect copyright of  
signals being transported across DVI or HDMIconnections. Several  
international regulatory bodies have recommended its incorporation into  
high-definition display and playback devices.  
HDMI™  
HDMIis an acronym for “High Definition Multimedia Interface.” It is a  
19-pin connector used for transferring combined digital audio and video.  
HDMIsupports standard, enhanced, and high-definition digital video  
signals, and is designed for use with VCRs, DVD players, personal  
computers, and set-top boxes. A DVI adapter can be used to transfer the  
video signal to an HDMI-capable display, although audio must be  
transferred from a different route, as DVI output does not support audio.

68  
HDTV  
Acronym for “High Definition Television,” a format that produces much  
greater picture quality than a standard television, and in a wide-screen  
format that matches that of a movie theater screen. The two most popular  
formats are 1080i and 720p, where the number represents how many  
horizontal scan lines they have, and the following letter represents whether  
the picture is interlaced, or the product of progressive scanning technology.  
Interlaced displays paint the odd-numbered scan lines and then the even-  
numbered lines to produce a picture, whereas progressive scan paints all of  
the scan lines at once. Both formats use an aspect ratio of 16:9. In contrast,  
standard North American television signals are displayed using 480  
interlaced (480i) scan lines with a more square aspect ratio of 4:3.  
Hue  
Refers to a specific color within the visible spectrum of light, defined by its  
dominant wavelength. A light wave with a central tendency within the  
range of 565-590 nm is visible as yellow. In the standard RGB color space  
used by most computer displays, hue refers to a coordinate of the color as  
described by its red, green, and blue values, minus any additional  
brightness or saturation values for that color.  
HydraVision™  
HydraVisionis ATI’s multi-monitor management software, enabling  
users to manage the display of multiple windows and applications across  
two or more adjacent monitors. It also includes a range of productivity  
features designed to effectively manage applications in this environment.  
HyperZHD  
HyperZHD includes a number of different technologies aimed at  
optimizing memory-bandwidth efficiency, particularly with respect to Z-  
buffer operations. The Z-Buffer, sometimes also called the Depth Buffer,  
stores information used to determine the placement of objects in a 3D  
environment with respect to the viewpoint of the observer. Reading and  
updating this buffer typically consumes more memory than any other part  
of the 3D rendering process, making it a major performance bottleneck.  
HyperZHD technology reduces the memory bandwidth consumed by the  
Z-Buffer, thereby increasing performance while also making the 3D  
environment more realistic.

Keyframe Interpolation  
This feature is also known as “morphing.” In an animation, a start and end  
point are picked as the key frames. In a 3D rendering, the start point could  
have a character with a neutral expression, and the end point could have  
that same character smiling. Additional frames are interpolated (inserted)  
between the two keyframes in order that “morphs” (transforms) the image  
so that there is a smooth transition between the key frames.  
KTX Buffer Region Extension  
This OpenGL® programming term refers to a feature that rapidly updates  
portions of the display of 3D modelling applications that change very  
quickly, or have been moved or occluded. It does this by optimizing the  
storage of buffer regions in the graphics card’s memory buffer. Other  
applications are typically not adversely affected when this is enabled.  
Lighting  
In 3D computer graphics, refers to aspects and quality of the virtual light  
source being used to make an object visible. Lighting can strongly affect  
the “mood” of a scene. For example, a “harsh” light could be a bare  
lightbulb that is glaringly bright on the objects closest to it while casting  
strong shadows in the background. A “softer” light would be more diffuse  
and not cast shadows, such as you would get outdoors on a typical overcast  
day.  
Mipmapping  
The most memory-intensive aspect of 3D graphics are the textures that give  
an object its realism (like wood, marble, leather, and cloth). Because  
objects in real life become less detailed as they move farther away from the  
viewer, 3D programmers simulate this by using less detailed, lower  
resolution texture maps on distant objects. These texture maps are merely  
scaled down versions of the main texture map used when the object is up  
close, and they use less memory.  
NTSC  
The name for the type of analog television signal used throughout the  
Americas (except Brazil) and in Japan. It draws a total of 525 vertical  
interlaced frames of video at a refresh rate of 60 Hz, making it relatively

flicker-free. The acronym refers to the National Television Systems  
Committee, which devised this color video standard in 1953.  
Offscreen Memory  
An area of memory used to preload images so that they can be quickly  
drawn to the screen. Offscreen memory refers to all of the remaining video  
memory not taken up by the front buffer, which holds the contents of the  
display screen currently visible.  
OpenGL®  
Short for “Open Graphics Library,” this is an industry standard for cross-  
platform 3D graphics development. It consists of a large number of  
functions that can be called upon in various programs, such as games,  
CAD, and virtual-reality systems, to produce complex 3D objects from  
simpler, more “primitive” building blocks. Implementations currently exist  
under Windows®, Mac OS® X, and various forms of Unix, including Linux®.  
ATI Overdrive  
ATI Overdrive maximizes the performance of the GPU by dynamically  
altering its speed to an optimal level depending on usage. An on-chip  
thermal sensor constantly monitors the temperature of the GPU, allowing  
for maximum clock speed to be maintained while avoiding overheating.  
PAL  
An acronym for “Phase Alternating Line”, the name for a video broadcast  
standard used in much of Europe (except France), most of Asia, the  
Middle-East, Africa and Australia. It draws a total of 625 vertical interlaced  
frames of video at a refresh rate of 25 Hz.  
PCI  
Acronym for “Peripheral Component Interconnect”, which is the  
specification for a type of computer bus used for attaching computer  
peripherals to a computer’s motherboard. PCI encompasses both integrated  
motherboard components (such as built-in graphical processors) and  
peripherals that fit into an expansion card slot, such as a separate graphics  
card. PCI replaced the older ISA and VESA bus standards, and was itself  
superseded by the AGP standard for the main graphics card bus.

71  
PCI Express® (PCIe)  
The successor standard to the PCI and AGP bus standards, with a  
significantly faster serial communications system, further opening up  
bandwidth for more communications between such peripherals as graphics  
cards and the computer’s CPU. PCIe cards can come in several physical  
configurations, the fastest currently being X16, which is typically used for  
graphic cards, and X1, typically used for other peripherals, such as separate  
multimedia cards.  
Pipeline  
In relation to computer graphic processors, refers to the number of separate  
arithmetic units available for rendering the output on a display. In general,  
more pipelines available on a graphical processor means there are more 3D  
rendering capabilities available, increasing overall 3D performance.  
Pixel  
All computer images are made up of tiny dots. Each individual dot is called  
a pixel, a word created from the term “picture element.” A pixel is the  
smallest indivisible unit of a digital image and can be only a single color.  
The size of the pixel depends on how the display resolution has been set.  
The smallest size a pixel can be is determined by the display’s dot pitch,  
which is measured in millimeters (mm).  
Refresh Rate  
Also referred to as “vertical refresh rate.” This is the rate at which a monitor  
or television can redraw the screen from top to bottom. NTSC television  
systems have a refresh rate of approximately 60 Hz whereas computer  
displays typically have refresh rates of 75 Hz or more. At refresh rates of  
70 Hz and lower, screen flicker is often noticeable.  
Rendering  
Rendering refers to the final drawing stages where the 2D image that  
appears on a display is derived from its 3D descriptions. What appears on  
the display may look three dimensional, but it is really just a 2D grid of  
pixels designed to appear that way.

72  
Resolution  
The resolution of any display is the number of pixels that can be depicted  
on screen as specified by the number of horizontal rows against the number  
of vertical columns. The default VGA resolution of many video cards is  
capable of displaying 640 rows of pixels by 480 columns. The typical  
resolution of current displays is set to higher values, such as 1024x768  
(XGA), 1280x1024 (SXGA), or 1600x1200 (UXGA).  
Saturation  
Refers to the intensity of a specific hue (color). A highly saturated hue is  
vivid and intense, whereas a less saturated hue appears more grey. A  
completely unsaturated color is grey. In terms of the RGB color model, a  
fully saturated color exists when you have 100% brightness in one of the  
three channels (say, red) and 0% in the two others (green and blue).  
Conversely, a fully desaturated color is one where all of the color values are  
the same. Saturation can therefore be thought of as the relative difference  
between the values of the channels.  
SCART  
SCART is an acronym for “Syndicat des Constructeurs d'Appareils  
Radiorécepteurs et Téléviseurs”. SCART is an 21-pin connector used  
mainly in Europe for transferring analog audio and video signals between  
VCRs, DVD players, personal computers, and set-top boxes. It is  
sometimes referred to as Péritel or the Euroconnector.  
Scissor Mode  
A graphical load-balancing scheme where two graphics cards are used to  
render two halves of an image display. One graphics card renders the top  
half of the screen while the second graphics card renders the bottom half.  
This configuration offers a form of dynamic load balancing between the  
two cards as each only needs to render 3D object details on only half of the  
screen instead of the full screen at any one time. This type of graphical  
operation is only available in Radeon® CrossFiregraphics cards running  
Microsoft® Direct 3D® and OpenGL® games or applications.  
SDTV  
SDTV is an acronym for “Standard Definition Television” that identifies  
lower resolution systems when compared to High Definition Television  
Download from Www.Somanuals.com. All Manuals Search And Download.  
                           
73  
(HDTV) systems. SDTV systems use the same 4:3 aspect ratio and 480  
scan lines to produce a picture as regular analog television sets, but digital  
decoding enhanced of the signal, displaying a sharper and crisper picture.  
SDTV broadcasts are either interlaced (480i) or use progressive scan  
(480p), the latter method providing the best overall image quality.  
SECAM  
An analog color video signal that originated in France, and is used in many  
other countries, including (but not limited to) much of Eastern Europe,  
parts of the Middle East and Asia. Like the PAL video standard, SECAM  
also draws a total of 625 vertical interlaced frames of video at a refresh rate  
of 25Hz, but uses a fundamentally different way of encoding its colors. The  
name is an acronym for “Séquential Couleur avec Mémoire,” which is  
French for “sequential color with memory.”  
Shadow Mask  
In CRT monitors, the shadow mask is a metal plate full of tiny holes that is  
attached to the inside of the glass screen. It focuses the beams from the  
electron guns at the back of the CRT. The distance between these holes is  
called the dot pitch.  
SmoothVisionHD  
SmoothVisionHD incorporates improved anti-aliasing, anisotropic  
filtering and 3Dccompression features designed to further enhance image  
quality. Anti-aliasing performance is improved, providing better overall  
detail and image quality. The enhanced anisotropic filtering ensures  
sharper and clearer pictures at higher frame rates, and the new 3Dc™  
compression technology makes it possible to display higher polygon counts  
for 3D rendered objects.  
Specular Highlight  
The bright, usually small, intense light reflected from a 3D surface with a  
high refraction value. From the intensity and spread of this highlight users  
can differentiate between a “hard,” smooth surface, such as metal or  
porcelain, or a “soft,” textured surface, such as fabric or skin.

74  
Super Anti-aliasing  
A feature that improves image quality by combining the results of full-  
screen anti-aliasing across two graphics cards in a CrossFire™  
configuration. The two graphics cards work on different anti-aliasing  
patterns within each frame. The results of which are combined by the  
compositing engine on the CrossFireMaster graphics card to produce 3D  
images featuring smoother contours, lines, and shading effects.  
SuperTiling  
A graphical load-balancing scheme where two graphics cards are used to  
render alternate small 32x32 pixel squares in a fine-grained checkerboard  
pattern. This configuration increases image rendering quality, as each card  
processes half of the complex 3D objects in the pixel squares. SuperTiling  
is better optimized for most applications than Scissor Mode (where two  
graphics cards are used to render the top and bottom halves of the screen),  
since the checkerboard pattern better ensures a more even distribution of  
what needs to be rendered. This type of graphical operation is only  
available in Radeon® CrossFiregraphics cards running Microsoft® Direct  
3D® games or applications.  
S-Video  
Short for “Separate Video,” S-Video is a type of analog video interface that  
produces a higher-quality signal compared to composite video. The signal  
is split into two separate channels— luminance (Y) and chrominance (C).  
Sometimes referred to as “Y/C video” or “Y/C”, the connectors typically  
contain 4-pins within a single connection housing and are commonly found  
on consumer DVD players, VCRs, game consoles, and related devices.  
Texel  
Short for “texture element,” the 3D equivalent of a pixel, describing the  
base unit of the surface of a 3D object, such as a sphere; for a 2D object,  
such as a circle, the base unit is a pixel.  
Texture Mapping  
In computer graphics, two-dimensional textured surfaces are referred to as  
texture maps. Texture mapping is the process by which a two-dimensional  
surface gets wrapped around a three-dimensional object so that the 3D  
object takes on the same texture qualities. For example, if you take a 2D  
Download from Www.Somanuals.com. All Manuals Search And Download.  
                                     
75  
textured surface that looks like cloth and wrap it around a 3D sphere, the  
sphere will now appear to have a cloth-like surface.  
Texture Preference  
Texture Preference is a feature enabling the user to select the texture quality  
level for the surface of a 3D object. Selecting the highest quality possible  
will provide the most realism, although it may also have some impact on  
the performance of any 3D intensive application.  
Transition Minimized Differential Signaling (TMDS)  
A technology designed to reduce electromagnetic interference (EMI) and  
improve the digital signal delivered to flat panel displays. Its encoding  
algorithm converts the original 8-bit graphic data into a more fault-tolerant  
10-bit signal, which is then converted back to its original 8-bit form at the  
display device. The signal is also DC-balanced, allowing for the option of  
transmitting the signal over fibre-optic cable. DVI connectors can  
incorporate up to two TMDS links, with each “link” comprised of the  
number of signals required for standard RGB output. Higher resolutions  
and refresh rates than standard are possible if multiple TMDS links are  
available by using multiple DVI connectors.  
Trilinear Filtering  
A sampling method used to produce realistic-looking 3D objects. Trilinear  
filtering averages one of the bilinear filter mipmap levels along with the  
standard mipmap samples.  
Vector Adaptive Deinterlacing  
A technique that provides smoother, less jagged edges for interlaced video  
playback. Interlaced video consists of alternating odd and even numbered  
scan lines, which are then mapped to an equivalent pixel-by-pixel display  
on a CRT or Flat Panel Display. Without correction, jagged lines appear in  
a video image either as doubled scan lines or lines that are improperly  
interpolated. With vector adaptive deinterlacing, the difference in pixel  
values is considered across multiple lines and alternating frames (using  
Pulldown detection on the interlaced video source), and then intelligently  
re-interpreted to produce smoother edges in interlaced video images.

VersaVision™  
An ATI technology enabling accelerated display rotation and scaling. Any  
desktop can now be rotated 90 degrees left or right, or even 180 degrees,  
while maintaining the full feature set of other ATI 2D and 3D technologies,  
such as SmoothVision. VersaVisionworks with single or multiple  
displays.  
Vertex Shader  
Three-dimensional objects displayed on a screen are rendered using  
polygons, each of which is made up of intersecting triangles. A vertex is a  
corner of a triangle where it connects to another triangle, and each vertex  
carries a considerable amount of information describing its coordinates in  
3D space, as well as its weight, color, texture coordinates, fog, and point  
size data. A vertex shader is a graphics processing function that  
manipulates these values, producing such things as more realistic lighting  
effects, improved complex textures such as hair and fur, and more accurate  
surface deformations such as waves rippling in a pool or the stretching and  
wrinkling of a character’s clothes as he or she moves.  
Vertex shader units  
A feature built into the graphical processor which renders the texture,  
magnitude and direction of the individual triangles that comprise each  
polygon of a given 3D object. The more vertex shader units available  
within the graphical processor, the more complex polygons that can be  
generated per clock cycle, and hence finer, more naturalistic detail and  
movement is possible.  
VGA Connector  
A type of graphics connector, sometimes also called an analog connector.  
It is the most common type of video connector available, consisting of 15-  
pins set in three rows. The “VGA” is an acronym for “Video Graphics  
Array,” which is also the name for the video resolution mode of 640x480  
pixels, the lowest standard resolution supported by virtually all video cards.  
Video ImmersionII  
A technology that integrates digital video features such as advanced  
adaptive de-interlacing, temporal filtering, and video gamma enhancement  
to produce high-quality video along with an integrated digital TV decode

77  
capability. It also supports component output support for EDTV displays at  
480i (interlaced scanning), 480p (progressive scanning), and for HDTV  
displays at 720p, and 1080i.  
VideoShaderHD  
A feature that integrates pixel-shading technology with video filtering and  
processing functions. It accelerates noise removal, de-blocking, adaptive  
de-interlacing, frame-rate conversion, color-space conversion, and more. It  
also enables better MPEG-2 decoding with motion compensation.  
VPU Recover  
A feature designed to significantly reduce the number of system crashes  
caused by problems occurring with the graphics hardware. If the display  
driver detects that the graphics processor has hung, VPU Recover will  
attempt to reset the graphics processor, eliminating the need for a system  
reboot and allowing users to continue using the computer without  
interrupting or losing their work.  
YPbPr  
A type of analog composite video signal that splits and compresses the  
standard Red/Green/Blue (RGB) colors of a television signal into separate  
luminance and color values. The “Y” stands for the luminance channel,  
while “Pb” and “Pr” represent the blue and red channels respectively, both  
of which have the luminance value subtracted from them. It is an equivalent  
color space to the chrominance-based YCbCr, which is used for digital  
video.  
Z-buffer  
The portion of video memory that keeps track of which onscreen elements  
can be viewed and which are hidden behind other objects. In the case of a  
3D image, it keeps track of which elements are occluded by the foreground  
in relation to the user’s perspective, or by another 3D object.
