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 left 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.

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.

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.

When you connect a digital input signal 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.
