							32  How to adjust your monitor  
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 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.
1.  Adjust the related display settings in different OSD menus. Settings that can be customized 
for game mode are:
• Brightness (see page 37)
• Contrast (see page 37)
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.
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.

settings will be applied all at once.
Adjusting display mode
To display images of aspect ratio other than 16:9 and size other than 24, you can adjust the 
display mode on the monitor.
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 
Picture Advanced and Display Mode.
3.  Select an appropriate display mode. The setting will take effect immediately.
Using Smart Scaling
You can resize your display by Smart Scaling.
1.  Go to 
Picture Advanced and Smart Scaling.
2.  Adjust the value.
Switch to the desired display mode first, and follow the instructions in Using Smart Scaling on page 33 to adjust 
the display size to precisely suit your needs.
• If one of the custom keys is preset for Smart Scaling, you can press the custom key and adjust the value 
directly.
• Your display may become unstable temporarily when being resized. This is a normal phenomenon and should 
not be considered as manufacturing defect.
• For more information on 
Smart Scaling, go to Smart Scaling on page 41.
