Adjusting Luminance
Though each preset is calibrated to a specific luminance level, the luminance can be adjusted post-
calibration. The luminance range for all calibrated color space presets can be adjusted from 48–250
cd/m2. The Native preset can be adjusted from 0–100% of maximum display luminance.
NOTE: Due to the way LEDs respond to voltage, the further you adjust luminance away from the
calibrated value, the less-accurate the luminance value reported by the OSD will be. HP recommends
that you calibrate your monitor to the desired working luminance.
To adjust luminance:
1. Press any button on the front bezel.
2. Press the bottom Open Menu button to open the OSD.
3. Select Color Space to display the color space configuration screen.
4. Use the Up/Down buttons to navigate to the Adjust Luminance option then press the Select

Understanding the Z27x Image Adjustment Options
The Z27x contains a number of special image adjustment options that are designed to fit specific
workflows in the media and entertainment industry. The following section describes these functions
from the perspective of their application in these workflows.
Use Video Levels (16–235)
This option is designed to support the accurate display of “video legal” signals that include footroom
below black and headroom above white. These types of signals are typically encountered when
working with video signals that conform to the complete ITU-R BT.709 standard as this standard
allows for excursions beyond black and white, rather than treating black and white as absolutes.
These signals are typically encountered in the following situations:
Viewing the HDMI or HD-SDI output from a video capture and playback card such as an AJA
Kona or Blackmagic Design DeckLink
●
Viewing an image in the Composer/Edit/Preview window in a non-linear video editing program
Viewing the output of a consumer Blu-Ray/DVD player
●
●
In all of these situations the video signal usually includes the BT.709 headroom and footroom.
Without this option enabled when viewed in a computer monitor the blacks and shadows are lighter,
the whites are darker, and colors have less saturation than the signal actually contains.
When this option is enabled the blacks will be clipped at the 8-bit value of 16 and the whites at the 8-
bit value of 235 (for 10-bit, the clipping will occur at the values of 64 and 960). The signal is then
remapped to display the signal in the correct visual range.
It is important to note that the source and pre-processing of the source video will impact whether this
setting should be enabled, but in many cases you will see a more-accurate image if you enable this
option. Note that you may need to adjust the lightness of your editing application interface after
enabling this setting.
To use video levels:
1. Press any button on the front bezel.
2. Press the bottom Open Menu button to open the OSD.
3. Select Image Adjustment to display the adjustment options screen.
4. Use the Up/Down buttons to navigate to the Use Video Levels option then press the Select
button to select it. The option will be checked when it is active.
Overscan the Frame
Though by default the Z27x displays all pixels in the image, when screening video dailies or an edit
revision it may be desirable to view the image in an overscanned mode, similar to how it is viewed on
a consumer digital television. The Overscan Frame by 5% option will enlarge the image so that only
that portion of the frame within the Action Safe region is displayed. Action Safe is defined as an area
that begins 5% inside the edge of the frame.
To use the Overscan Frame mode:
Understanding the Z27x Image Adjustment Options 31
1. Press any button on the front bezel.
2. Press the bottom Open Menu button to open the OSD.
3. Select Image Adjustment to display the adjustment options screen.
4. Use the Up/Down buttons to navigate to the Overscan Frame by 5% option then press the
Select button to select it. The option will be checked when it is active.
Show Only the Blue Channel
As the human is least-sensitive to changes in blue, most compression and encoding algorithms
assign the least amount of bandwidth to the blue channel. Because of this, compression/encoding
errors are most-easily seen when viewing the blue channel. The Z27x allows the user to view just the
blue channel, temporarily turning the red and green channels off, so that the image can be inspected
for these errors.
To view only the blue channel:
1. Press any button on the front bezel.
2. Press the bottom Open Menu button to open the OSD.
3. Select Image Adjustment to display the adjustment options screen.
4. Use the Up/Down buttons to navigate to the Show Blue Channel Only option then press the
Select button to select it. The option will be checked when it is active.
Using the Z27x Aspect Ratio Management Options
The Z27x includes a number of special aspect ratio management options that go far beyond what is
typically found in a computer monitor. This section discusses these options, with a focus of how these
options are integrated into specific workflows.
The “Fill To” Options
These options are used to determine how the source input is displayed onscreen if its resolution is
different from the monitor’s native resolution of 2560×1440.
Fill to Source Aspect Ratio (Proportional)
This option will maintain the aspect ratio of the source input, making the image as large as possible,
centering it in the monitor, and using 0% black to fill the unused areas of the screen. For example, a
source input that is narrower than 16×9 will be displayed at full height with black bars to the left and
right of the source image, and a source input that is wider than 16×9 will be the displayed at full width
with black bars above and below the source image.
Fill to Source Aspect Ratio is the default and is the option most-suitable to the majority of workflows.
Fill to Entire Screen (Non-Proportional)
This option will distort non-16×9 source aspect ratios to force them to fit within the monitor’s 16×9
aspect ratio. The resulting image will take up the entire display and will either be stretched
horizontally (for narrower aspect ratios) or vertically (for wider aspect ratios).
Use Fill to Entire Screen if the source aspect ratio is irrelevant and you want the entire screen to be
filled, regardless of the distortion that may be caused.
32 Chapter 4 Operating the Monitor
Fill to Screen Width (Proportional)
This option is to be used for specific workflows with source video that is narrower than the monitor’s
native 16×9 aspect ratio. In some film workflows it is desired to render the animation or visual effects
at a 4×3 aspect ratio and perform a “center extraction” for widescreen delivery. If enabled, this option
will resize the source image so that the width matches the monitor width. Then the source image is
centered vertically and the top and bottom of the image are cropped off, leaving a 16×9 “center
extraction” of the 4×3 frame. The proportions of the source image are maintained.
The Fill to Screen Width option should be used when vertical center extractions are desired as part of
the dailies or review screening process.
Fill to Screen Height (Proportional)
This option is to be used for specific workflows with source video that is wider than the monitor’s
native 16×9 aspect ratio. In some film workflows it is desired to see a 16×9 horizontal extraction of a
wider source aspect ratio. If enabled, this option will resize the source image so that the height
matches the monitor height. Then the source image is centered horizontally and the top and bottom
of the image are cropped off, leaving a 16×9 “center extraction” of the wider frame. The proportions of
the source image are maintained.
The Fill to Screen Height option should be used when horizontal center extractions are desired as
part of the dailies or review screening process.
Pixel-for-Pixel
This option is to be used for source video that has a lower resolution than the monitor’s native
resolution of 2560×1440 and you wish to view the image without any scaling applied. For example, if
your source image has a 1920×1080 resolution and you wish to inspect the pixels to ensure that
there are no rendering issues in the displayed content, you may want to use this option.
This option has a specific functionality when the source video has a higher resolution than
2560×1440. This functionality will be covered in the next section.
“Fill To” Examples
The following illustrations summarize how a 4×3 source image is displayed using the “Fill to” options.
The Fill to Screen Height option is not applicable to this source aspect ratio so it is not shown.

has been included in the Z27x in anticipation of future use and codification.
In addition, the display supports aspect ratio masking for the two standard aspect ratios, 1.85:1 and
2.39:1, within the DCI image container. When DCI aspect ratio masking is selected the source video
is masked to only show the pixels within the specified aspect ratio. The following table lists the active
pixels that will be displayed for each image container and aspect ratio.

Finally, special display modes for 4K input resolutions are also provided to facilitate the display of 4K
content on the Z27x.
Using the Digital Cinema Display Options
All of the digital cinema display options are located in the OSD on the Main Menu > Image
Adjustment > Aspect Ratio Display page. These options are unavailable and the menu option
dimmed unless one of the following resolutions is being displayed via the active video input:
2048 × 1080
4096 × 2160
3840 × 2160
●
●
●
NOTE: Though the Digital Cinema Options menu is available for the 3840 × 2160 resolution, the
aspect ratio options are not available because 3840 × 2160 is not a DCI container size.
To access the digital cinema display options:
1. Connect a computer or video device to the monitor that is configured to output a 2048 × 1080 or
4096 × 2160 resolution.
2. Press any button on the front bezel.
3. Press the bottom Open Menu button to open the OSD.
4. Select Image Adjustment to display the adjustment options screen.
5. Select Aspect Ratio Display to display the display options.
6. Select Digital Cinema Options to display the digital cinema options.
The following DCI Aspect Ratio options are available in the Image Region section of the Digital
Cinema Options page.
Show Entire DCI Container
This is the default option and will show the entire DCI 2048 × 1080 or 4096 × 2160 frame.
Crop to DCI 1.85:1 Aspect Ratio
This option crops 25 pixels from the left and right edges of the frame (for 2048-wide sources, 50
pixels from the left and right edges for 4096-wide sources). The resultant image is then displayed as
specified using the Aspect Ratio Display options described in the previous section.
36 Chapter 4 Operating the Monitor
Crop to DCI 2.39:1 Aspect Ratio
This option crops 111 pixels from the top and bottom edges of the frame (for 2048-wide sources, 222
pixels from the top and bottom edges for 4096-wide sources). The resultant image is then displayed
as specified using the Aspect Ratio Display options described in the previous section.
Show Cropped Region
When this option is enabled, rather than cropping and resizing the image to the selected aspect ratio,
the image is not resized, but the region outside the desired aspect ratio is instead overlaid with a
partially-transparent black mask. This option is useful, for example to check the top line in a 2.39:1
aspect ratio and see what information may be available, if the headroom needs to be adjusted via
reframing.
Set Cropped Region Opacity
This option is available when Show Cropped Region is active and allows you to specify the amount of
opacity applied to the cropped region. Adjust as needed to achieve the desired balance between the
active and cropped regions of the frame.
Displaying 4K Source Video
Though it only has a native resolution of 2560 × 1440, the Z27x can receive and display a 4096 ×
2160 or 3840 × 2160 input signal. Multiple scaling and display options are provided. To provide the
highest quality display of 4K source video on the Z27x the scaling algorithm has been specifically
tuned to provide a naturalistic scaling without any sharpness or edge enhancement.
When a 4096 × 2160 or 3840 × 2160 signal is input into the monitor, the following scaling options are
available via the 4K Sources section of the Digital Cinema Options page. If DCI aspect ratio cropping
has been selecting, these options are applied after the image is cropped.
Obey Aspect Ratio Display Option
This default option will display the image according to the selected “Fill to” Aspect Ratio Display
these options.
Scale and Show Center Extraction
If selected, the center 16×9 region of the frame will be displayed with the areas outside of this center
region cropped, similar to the Fill to Screen Height option discussed previously. The amount of the
image shown in the center extraction is dependent on whether the entire container or an aspect ratio
is displayed.
Scale and Show Left Side of Frame
If selected, the left-most 16×9 region of the frame will be displayed with the areas outside of this left
side region cropped, similar to the Fill to Screen Height option discussed previously. The amount of
the image shown in the left extraction is dependent on whether the entire container or an aspect ratio
is displayed.
Scale and Show Right Side of Frame
If selected, the right-most 16×9 region of the frame will be displayed with the areas outside of this
right side region cropped, similar to the Fill to Screen Height option discussed previously. The amount
of the image shown in the right extraction is dependent on whether the entire container or an aspect
ratio is displayed.
Working with 2K and 4K Digital Cinema Image Formats 37
Show 4K Source Video Pixel-for-Pixel
If the Aspect Ratio Display is set to Pixel-for-Pixel and the 4K Source option is set to Obey Aspect
Ration Display Option, 4096 × 2160 and 3840 × 2160 source video can be displayed pixel-for-pixel.
Two different display options are available, Show 4K Corner and Scroll 4K Region. Accessing these
two options require that a specific function be mapped to one of the four bezel function buttons. Refer
buttons. The following sections describe the usage of these two options.

The image will continue to switch between the five positions for each button press until Pixel-for-Pixel
display is disabled.
Scroll 4K Region
When viewing a 4K source as pixel-for-pixel, press the Scroll 4K Region button to display navigation
arrows, allowing you to move around the frame to the desired area. When this option is enabled, a
pop-up window will appear in lower right region of the monitor that shows the entire 4K image and
indicates the area of interest being show full-screen. Use the directional bezel buttons to shift the
area of interest. When this option is turned off the pop-up will vanish, but the area of interest will
continue to be displayed.
Using Picture-in-Picture (PIP) and Picture-beside-Picture
(PBP)
The monitor supports both PIP, where one source is overlaid over another, and PBP, where one
source is positioned adjacent to one another either horizontally (for landscape orientation) or vertically
(for portrait orientation).
To use PIP or PBP:
1. Connect a secondary input source to the monitor.
2. Press one of the five front bezel buttons to activate the buttons, and then press the bottom Open
Menu button to open the OSD.
3. In the OSD, select PIP Control > PIP On/Off and then select either Picture-in-Picture or Picture-
beside-Picture.
4. The monitor will scan the secondary inputs for a valid input and use that input for the PIP/PBP
picture. If you want to change the PIP/PBP input, select PIP Input in the OSD and select the
desired input (DisplayPort 1, DisplayPort 2, or HDMI).
5. If you want to change the size of the PIP, select PIP Size in the OSD then select either Enlarge,
Reduce, Set to Maximum Size, Set to Minimum Size, or Reset to Default Size. At maximum size,
the PIP will display pixel-for-pixel all input formats up to 2048 × 1080. This is to facilitate using
38 Chapter 4 Operating the Monitor
the PIP as a confidence monitor. Please refer to the following section for more information on
this usage.
6. If you want to adjust the position of the PIP, select PIP Position in the OSD, then select either
Top Left, Top Right, Bottom Left, Bottom Right, or Fine Tune Position.
Using PIP as a Confidence Monitor
As the PIP is primarily designed to be used at as a confidence monitor – at 100% size for 1080- or
720-line content, including DCI 2K content – many of the Image Adjustments available for the main
input are also available for use within the PIP. Refer to Understanding the Z27x Image Adjustment
further information on these adjustments.
The following adjustments are available within the PIP. None are enabled by default.
Use Video Levels (16–235)
If monitoring a video signal output from a video capture card such as an AJA Kona or Blackmagic
Design Decklink, this option should usually be enabled as video levels are typically used in video
post-production workflows.
Overscan Within PIP
Use this option if you wish to see how your video output will be displayed on a consumer television.
This is especially useful when ensuring that the margins for lower third graphics are correct and
nothing will be cut off on a consumer television.
Digital Cinema Options
If you display a 2048 × 1080 signal as a PIP, you can instruct the monitor to display either the full DCI
container or crop the PIP to either the 1.85:1 or 2.39:1 aspect ratio. If cropping to an aspect ratio, the
shape of the PIP will change to the chosen aspect ratio. Black bars will not be visible at the edges of
the PIP.
Changing the Bezel Button Functions
You can change the top-level front bezel button functions from their default values so that when the
buttons are activated you can quickly access commonly used commands.
The following commands can be mapped:
Color Space Select – displays a list of available color space presets. Use to quickly switch from
one color space preset to another. This command is mapped to Function Button One by default.

Introduction to Color Calibration
The Z27x includes an internal color calibration and color management engine and does not require
software to be installed on a host computer in order to be calibrated. The following section discusses
the fundamentals of user calibration on the Z27x. A detailed discussion of calibration is covered in the
HP DreamColor Z27x Advanced User Guide.
The Z27x has been pre-calibrated at the factory to accurately display six of the most-frequently used
industry standard color spaces. In addition, all color spaces presets can be recalibrated by the user.
The following table lists the out-of-the box calibrated color space presets and provides information on
their calibrated configuration.

As a display is used, the backlight ages and the light output changes. As a result, a color-critical
display must be recalibrated from time to time to ensure color accuracy. HP recommends that the
Z27x be recalibrated every one thousand hours of use. The number of hours since calibration can be
displayed via the Display Information option in the Main Menu of the OSD or via the Show Display
Information command.
HP supports a variety of color measurement instruments, from inexpensive solutions that sell for a
few hundred dollars to colorimeters and spectroradiometers costing tens of thousands of dollars. The
following measurement instruments are supported:

Photo Research PR-740/745 SpectraScan spectroradiometer
Konica Minolta CA-310 Display Color Analyzer colorimeter
Please refer to the HP DreamColor Z27x Advanced User Guide or the Calibration Best Practices
white paper for the recommended configuration of these instruments.
The HP DreamColor Calibration solution is available directly from HP.com and HP resellers. Contact
the manufacturers of the other supported instruments for pricing and availability.
NOTE: As the connection to the Z27x is made via USB, the Photo Research and Konica Minolta
units must have USB connection, which is optional on some models.
Two different calibration workflows are supported:
Onscreen menu-driven calibration
HP StudioCal XML-driven calibration
●
●
This user guide only covers the onscreen menu-driven calibration option. Please refer to the HP
DreamColor Z27x Advanced User Guide or the Calibration Best Practices white paper for information
on the XML-driven option.
Preparing to Calibrate
In order to calibrate, the Z27x internal processor must be enabled. To meet the energy savings
requirements of Energy Star 6.0, the internal processor is disabled at the factory.
To enable the Z27x internal processor:
1. Press one of the five front bezel buttons to display the button labels and then press the bottom
Open Menu button to open the OSD.
2. In the OSD, select Management > Manage Internal Processor.
3. Choose Enable then press Select to turn the processor on.
4. Press Exit to exit the OSD.
Once enabled, wait approximately one minute for the processor to fully boot before beginning
calibration.
CAUTION: It is strongly recommended that calibration be performed in a darkened room. Stray light
bouncing off the monitor will negatively impact calibration accuracy.
Calibrating the Z27x Using the Onscreen Menus
Once the internal processor has booted, connect the measurement instrument to one of the
DreamColor USB ports on the bottom of the Z27x.
Introduction to Color Calibration 53
After 15–60 seconds, depending on the measurement instrument, the Z27x will display a message
asking you how you wish to calibrate the monitor.
Recalibrate the Current Preset
This option will recalibrate the active color space using its current configuration. This is the
recommended procedure for recalibrating a color space that is configured the way you need it to be.
After choosing this option the display will show an instrument alignment target. Align your instrument
with the center of the crosshairs then press the Start Calibration bezel button.
NOTE: If using the HP DreamColor Calibration Solution, be sure to rotate the ambient light filter out
of the way before using the instrument. For other instruments be sure to remove the lens cap prior to
calibration.
Depending on the instrument used, calibration may take between a few minutes and half an hour.
The screen will display a variety of colors during the calibration process then display a calibration
complete message at the end of calibration.
Select and Modify a Preset
This option allows you to choose the color space to calibrate and change the gamut, white point,
gamma, and luminance targets. This is the recommended procedure if you want to modify a color
space preset from its factory configuration
When this option is selected you will be presented with a series of screens from which you can
choose the desired calibration targets. Each screen allows you to select from a set of standard
options, as documented below. If you wish to create a custom set of calibration targets use the
StudioCal XML option, documented in the Z27x Advanced User Guide.
The following standard options are provided for you to select from:

values for the Native color space.
You can enable or disable Auto EDID Update in the OSD:
Auto EDID Update 55
1. Press any of the five front bezel buttons on the right side of the front bezel to activate the

C LCD Monitor Quality and Pixel Policy
The TFT monitor uses high-precision technology, manufactured according to HP standards, to
guarantee trouble-free performance. Nevertheless, the display may have cosmetic imperfections that
appear as small bright or dark spots. This is common to all LCD displays used in products supplied by
all vendors and is not specific to the HP LCD. These imperfections are caused by one or more
defective pixels or sub-pixels.
A pixel consists of one red, one green, and one blue sub-pixel.
●
●
A defective whole pixel is always turned on (a bright spot on a dark background), or it is always
off (a dark spot on a bright background). The first is the more visible of the two.
A defective sub-pixel (dot defect) is less visible than a defective whole pixel and is small and
only visible on a specific background.
●
To locate defective pixels, the monitor should be viewed under normal operating conditions, in normal
operating mode at a supported resolution and refresh rate, from a distance of approximately 50 cm
(20 in).
HP expects that, over time, the industry will continue to improve its ability to produce LCDs with fewer
cosmetic imperfections and HP will adjust guidelines as improvements are made.
