Getting the most from your BenQ monitor  
To gain the most benefit from your new BenQ LCD 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 recognize 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 either an automatic (new) or  
upgrade (existing) installation, 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.  
To check the name of the purchased model, refer to the specification label on the back of the monitor.

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 Getting the most from your BenQ monitor on page 23.  
When Windows starts, it will automatically detect the new monitor and launch the Found New  
Hardware 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.  
To find the suitable driver files for the purchased model, refer to the following table.

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 8, Windows 7, 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.

Picture optimization  
The default picture mode is RTS, which is designed for RTS games. If you prefer other picture modes, go to  
Picture Advanced and change setting in Picture Mode.  
The easiest way to obtain an optimal display from an analog (D-Sub) input is to use the Auto  
Adjustment function. Go to Display and Auto Adjustment to optimize the currently displayed  
image to the screen.  
When you connect a digital video output using a digital (DVI or HDMI) cable to your monitor, 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 Adjustment 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 any of the control keys to bring up the hot key menu. Select Menu to enter the main  
menu.  
3. Go to Display and Auto Adjustment.  
4. If you notice a vertical noise (like a curtain effect-shimmering of vertical lines), select Pixel  
Clock and adjust the monitor until the noise disappears.  
5. If you notice a horizontal noise, select Phase and adjust the monitor until the noise  
disappears.  
Customizing the hot keys  
The top 3 control keys (also called custom keys) perform as hot keys to provide direct access  
to pre-defined functions. You can change the default setting and designate different functions for  
these keys.  
1. Press any of the control keys to bring up the hot key menu, and press Menu to access the  
main menu.  
2. Go to System.  
3. Select the custom key you want to change.  
4. In the sub menu, select a function that can be accessed by this key. A pop-up message will  
appear, showing that the setup is complete.  
Setting up your own game mode  
There are several preset picture modes on your monitor that are suitable for games. To better  
suit your needs, you can change and save the related display settings, and switch to your own  
game mode easily.

Troubleshooting  
Frequently asked questions (FAQ)  
The image has a faulty coloration.  
• The default Picture Mode is RTS, which is designed for RTS games. If you prefer other  
picture modes, go to Picture Advanced and change setting in Picture Mode.  
• If the image has a yellow, blue or pink appearance, go to Picture and Reset Color, and then  
choose YES 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.  
The image is blurred.  
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.  
How do you use a VGA extension cable?  
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.  
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".  
Troubleshooting  
47  
   
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.  
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 supply mains socket, the external power supply and the mains 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  
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 it is preset to be locked, press and hold any key for 10  
seconds.  
No sound can be heard from the built-in speakers (for models with speakers only):  
• Check whether Line In is properly connected.  
• Increase the volume (volume may be muted or too low).  
• Remove your headphone and/or external speakers. (If they are connected to the monitor,  
the built-in speakers are automatically muted.)  
48  
Troubleshooting  
No sound can be heard from the connected external speakers.  
• Remove your headphone (if the headphone is connected to the monitor).  
• Check whether the headphone jack is properly connected.  
• If the external speakers are USB-powered, check whether the USB connection is OK.  
• Increase the volume (volume may be muted or too low) on the external speakers.
