							  37   How to adjust your monitor

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.
2.  Select a desired display mode. See Adjusting display mode on page 39. 
3.  Resize your display by 
Smart Scaling. See Using Smart Scaling on page 40.
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 
Downloading more game modes using Game Mode Loader on page 39.

Picture optimization
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.
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:
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.
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.
