3. How to assemble your monitor hardware  
If the computer is turned on you must turn it off before continuing.  
Do not plug-in or turn-on the power to the monitor until instructed to do so.  
1. Attach the monitor base.  
Please be careful to prevent damage to the monitor.  
Placing the screen surface on an object like a stapler or a  
mouse will crack the glass or damage the LCD substrate  
voiding your warranty. Sliding or scraping the monitor  
around on your desk will scratch or damage the monitor  
surround and controls.  
Protect the monitor and screen by clearing a flat open area  
on your desk and placing a soft item like the monitor  
packaging bag on the desk for padding.  
Gently lay the screen face down on a flat clean padded  
surface.  
While holding the monitor firmly against the desk, pull  
the monitor stand arm upwards clear of the monitor.  
Orient and align the stand base socket with the end of the  
stand arm, then push them together until they click and  
lock into place.  
Gently attempt to pull them back apart to check that they  
have properly engaged.  
Carefully lift the monitor, turn it over and place it upright  
on its stand on a flat even surface.  
You should position the monitor and angle the screen to  
minimize unwanted reflections from other light sources.

2. Connect the PC video cable.  
Either  
Do not use both DVI-D cable and D-Sub cable on the  
same PC. The only case in which both cables can be  
used is if they are connected to two different PCs with  
appropriate video systems.  
Connect one end of the DVI-D cable to the monitor  
DVI-D jack and the other end to the DVI-D port on your  
computer. (optional)  
The DVI-D format is used for direct digital connection  
between source video and digital LCD monitors or  
projectors. The digital video signals produce a superior  
quality picture than analog video signals.  
Or  
Connect the plug of the D-Sub cable (at the end without  
the ferrite filter) to the monitor D-Sub jack. Connect the  
other plug of the D-Sub cable (at the end with the ferrite  
filter) to the computer video D-Sub jack.  
Tighten all finger screws to prevent the plugs from acci-  
dently falling out during use.  
3. Connect the power cable to the monitor.  
Plug one end of the power cord into the jack labelled  
‘POWER IN’ on the rear of the monitor. Do not connect  
the other end to a power outlet just yet.

4. Route the cables via the cable clip.  
Release the cable retaining clip by squeezing the clip  
inwards as illustrated. Position the cables together and  
reinsert the clip over them to retain the cables neatly in  
place behind the monitor stand.  
5. Connect-to and turn-on the power.

1. Prepare the monitor and area.  
Turn off the monitor and the power before unplugging the  
power cable. Turn off the computer before unplugging the  
monitor signal cable.  
Please be careful to prevent damage to the monitor.  
Placing the screen surface on an object like a stapler or a  
mouse will crack the glass or damage the LCD substrate  
voiding your warranty. Sliding or scraping the monitor  
around on your desk will scratch or damage the monitor  
surround and controls.  
Protect the monitor and screen by clearing a flat open area  
on your desk and placing a soft item like a towel on the  
desk for padding, before laying the screen face down on a  
flat clean padded surface.

4. Getting the most from your BenQ monitor  
To gain the most benefit from your new BenQ color LCD flat screen monitor, you should install  
the custom BenQ LCD Monitor driver software as provided on the BenQ LCD Monitor CD-ROM.  
The circumstances under which you connect and install your BenQ LCD Monitor will determine  
which process you need to follow to successfully install the BenQ LCD Monitor driver software.  
These circumstances relate to which version of Microsoft Windows you are using, and whether  
you are connecting the monitor and installing the software onto a new computer (without existing  
monitor driver software), or whether you are upgrading an existing installation (which already has  
existing monitor driver software) with a newer monitor.  
In either case however, the very next time you turn on your computer (after connecting the  
monitor to your computer), Windows will automatically recognise the new (or different)  
hardware, and will launch its Found New Hardware wizard.  
Follow the wizard instructions until it asks you to select a monitor model. At that point, click the  
Have Disk button, insert the BenQ LCD Monitor CD-ROM and select the appropriate monitor  
model. Further details and step-by-step instructions for both an automatic (new) or upgrade  
(existing) installation follow. See:  
If you require a User Name and Password to login to your Windows computer, you must be logged on as  
an Administrator or as a member of the Administrators group in order to install the monitor driver software.  
Furthermore, if your computer is connected to a network which has security access requirements, network  
policy settings may prevent you from installing software on your computer.

How to install the monitor on a new computer  
This instruction details the procedure for selecting and installing the BenQ LCD Monitor driver  
software on a new computer which has never had a monitor driver installed before. This  
instruction is only suitable for a computer which has never been used before, and for which the  
BenQ LCD Monitor is the first ever monitor to be connected to it.  
If you are adding the BenQ LCD Monitor to an existing computer that has already had another monitor  
connected to it (and has monitor driver software installed), you should not be following these instructions.  
You should instead be following the instructions for How to upgrade the monitor on an existing computer.  
1. Follow the instructions in How to assemble your monitor hardware on page 7.  
When Windows starts, it will automatically detect the new monitor and launch the Found New Hard-  
ware Wizard. Follow the prompts until it displays the option to Install Hardware Device drivers.  
2. Insert the BenQ LCD Monitor CD-ROM into a CD drive on the computer.  
3. Check Search for a suitable driver for my device option, and click Next.  
4. Check the option for CD-ROM drives (uncheck all others) and click Next.  
5. Look to confirm that the wizard has selected the correct name of your monitor and click  
Next.  
6. Click Finish.  
7. Restart the computer.

How to upgrade the monitor on an existing computer  
This instruction details the procedure for manually updating the existing monitor driver software  
on your Microsoft Windows computer. It is currently tested as compatible for Windows XP and  
Windows Vista Operating System (OS).  
The BenQ LCD Monitor driver for your model may well function perfectly with other versions of Windows,  
however, as at the time of writing, BenQ has done no testing of this driver on other versions of Windows  
and cannot guarantee its operation on those systems.  
Installing monitor driver software involves selecting an appropriate information file (.inf) on the  
BenQ LCD Monitor CD-ROM for the particular model monitor you have connected, and letting  
Windows install the corresponding driver files from the CD. You need only steer it in the right  
direction. Windows has an Upgrade Device Driver Wizard to automate the task and guide you  
through the file selection and installation process.

5. Picture optimization  
The easiest way to obtain an optimal display from an analog (D-Sub) input is to use the AUTO key  
function. Press the AUTO key to optimize the currently displayed image to the screen.  
When you connect a digital video output using a digital (DVI) cable to your monitor, the AUTO key and the  
Auto Adjustment function will be disabled, because the monitor will automatically display the best image.  
Please ensure that the connected graphic card on your computer is set to the native resolution of the  
monitor when you use the AUTO key function.  
If you wish, you can always adjust the screen geometric settings manually using geometry menu  
items. To assist you in this endeavour, BenQ has provided a screen test image utility which you can  
use to check for screen color, grayscale and line gradient display.  
1. Run the test program auto.exe from CD-ROM. You could also use any other image, such as  
the desktop of your operating system. However, we recommend that you use auto.exe. As you  
run auto.exe, a test pattern displays.  
2. Press the AUTO key on the monitor.  
3. Press the MENU key to access the monitor On-Screen Display (OSD) menu.  
4. Use the W or X keys to select DISPLAY and press the ENTER key to enter the menu.  
5. If you notice a vertical noise (like a curtain effect-shimmering of vertical lines), press the W  
or X keys to select Pixel Clock and press the ENTER key. Then press the W or X keys to  
adjust the monitor until the noise disappears.  
6. If you notice a horizontal noise, press the W or X keys to select Phase and press the ENTER  
key. Then press the W or X keys to adjust the monitor until the noise disappears.

Remove the extension cable for the test. Is the image now in focus? If not, optimize the image by  
working through the instructions in the "Adjusting the refresh rate" section on the link  
"Adjusting the Screen Resolution". It is normal for blurring to occur due to conduction losses  
in extension cables. You can minimize these losses by using an extension cable with better  
conduction quality or with a built-in booster.  
Does the blurring only occur at resolutions lower than the native (maximum) resolution?  
Read the instructions on the link "Adjusting the Screen Resolution" on the CD. Select the  
native resolution.  
Pixel errors can be seen:  
One of several pixels is permanently black, one or more pixels are permanently white, one or  
more pixels are permanently red, green, blue or another color.  
Clean the LCD screen.  
Cycle power on-off.  
These are pixels that are permanently on or off and is a natural defect that occurs in LCD  
technology.  
The image has a faulty coloration:  
It has a yellow, blue or pink appearance.  
Select MENU > PICTURE > Color > Reset Color, and then choose “YES” in the “Caution”  
message box to reset the color settings to the factory defaults.  
If the image is still not correct and the OSD also has faulty coloration, this means one of the three  
primary colors is missing in the signal input. Now check the signal cable connectors. If any pin is  
bent or broken off, please contact your dealer to get necessary support.  
No image can be seen:  
Is the prompt on the display illuminated in green?  
If the LED is illuminated in green and there is a message “Out of Range” on the screen, this means  
you are using a display mode that this monitor does not support, please change the setting to one  
of the supported mode. Please read the “Preset display modes” section from the link  
"Adjusting the Screen Resolution".  
Faint shadow from the static image displayed is visible on the screen:  
Activate the power management function to let your computer and monitor go into a low  
power "sleep" mode when not actively in use.  
Use a screensaver to prevent the occurrence of image retention.

Troubleshooting  
Is the prompt on the display illuminated in orange?  
If the LED is illuminated in orange, the power management mode is active. Press any button on  
the computer keyboard or move the mouse. If that does not help, check the signal cable  
connectors. If any pin is bent or broken off, please contact your dealer to get necessary support.  
Is the prompt on the display not illuminated at all?  
Check the power input jack, the external power adapter and the mains power switch.  
The image is distorted, flashes or flickers:  
Read the instructions on the link "Adjusting the Screen Resolution" on the CD, and then select  
the correct resolution, refresh rate and make adjustments based on these instructions.  
You are running the monitor at its native resolution, but the image is still distorted.  
Images from different input sources may appear distorted or stretched on the monitor running at  
its native resolution. To have the optimal display performance of each type of input sources, you  
can use the "Display Mode" function to set a proper aspect ratio for the input sources. See Display  
Mode on page 25 for details.  
The image is displaced in one direction:  
Read the instructions on the link "Adjusting the Screen Resolution" on the CD, and then  
select the correct resolution, refresh rate and make adjustments based on these instructions.  
The OSD controls are inaccessible:  
To unlock the OSD controls when the OSD is preset to be locked, press and hold the “MENU”  
key for 15 seconds to enter the “OSD Lock” option and make changes.  
Alternatively, you may use the W or X keys to select “NO” in the “OSD Lock” submenu from  
the “OSD Settings” menu (under SYSTEM), and all OSD controls will be accessible.
