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 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.
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.

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.

Initial setup for playing games
You can optimize the monitor to enhance your gaming experience. You might want to start
with the following settings.
1. Set the screen refresh rate to 120 Hertz (120 Hz).
a. Right-click the desktop and select Screen resolution. Click Advanced settings. Under
the Monitor tab, change the screen refresh rate to 120 Hertz. And then click Apply and
Yes to confirm the change.
Depending on the operating system on your PC, different procedures should be followed to adjust the screen
refresh rate. Refer to the Help document of your operating system for details.

b. Go to the setup menu in your game, and change the frame rate or screen refresh rate to
120 Hz. Refer to the Help document that came with your game for details.
To check if the screen refresh rate has been changed, select Menu from the hotkey menu
on your monitor, and go to System and Information. The refresh rate in both Current
Resolution and Optimum Resolution should be 120 Hz.
If 120 Hz is not available in your menus, check the following:
• make sure the DVI-D Dual Link cable is properly connected to your computer and the monitor
• make sure your GPU supports 120 Hz
• make sure your game supports 120 Hz.
4. Select an appropriate game mode for your game. FPS is for FPS games, while RTS is for
RTS games. For more game modes, please download by Game Mode Loader. See

Picture optimization
The default picture mode is FPS1, which is designed for FPS 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, HDMI, or DP) 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, or the wheel, or the return button on the S Switch 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, or the wheel, or the return button on the S Switch to bring
up the hot key menu.
2. Select Menu to access the main menu.
3. Go to System.
4. Select the custom key you want to change.
5. 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.
1. Adjust the related display settings in different OSD menus. Settings that can be customized
for game mode are:

How to adjust your monitor
Download from Www.Somanuals.com. All Manuals Search And Download.
2. After all settings are done, go to Save Settings and save as one of the game modes.
Alternatively, press and hold one of the game mode buttons (labeled 1~3) on S Switch to
save as one of the game modes.
3. If you want to switch to your game mode at any time, go to Picture Advanced and
Picture Mode, and select the game mode you saved in Step 2. Your preferred display
settings will be applied all at once.
Alternatively, press one of the game mode buttons (depending on your settings in Step 2)
on S Switch to switch to the desired game mode quickly.
BenQ offers more optimized game modes on the website. If you prefer to use these settings, refer to
Downloading more game modes using Game Mode Loader
Instead of customizing your own display settings, you can download the game modes available
on the BenQ website and apply the settings directly.
2. Download and install the game mode loader.
3. Follow the on-screen instructions to complete the setup.
4. Go to Picture Advanced and Picture Mode on your monitor, and select the game mode
you just downloaded to apply the settings directly.
Internet connection is required for this operation.
Adjusting display mode
To display images of aspect ratios other than your monitor aspect ratio and sizes other than
your display size, you can adjust the display mode on the monitor. For the aspect ratio and
display size of your monitor, see the specifications on the CD.

Troubleshooting
Frequently asked questions (FAQ)
The image has a faulty coloration.
• The default Picture Mode is FPS1, which is designed for FPS 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.
