5. Picture optimization

The easiest way to obtain an optimal display from an analog (D-Sub) input is to use the 

AUTO

 key 

function. Press the 

AUTO

 key to optimize the currently displayed image to the screen. 

When you connect a digital video output using a digital (DVI) cable to your monitor, the 

AUTO

 

key and 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 key 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 the 

AUTO

 key on the monitor.

3. Press the 

MENU

 key to access the monitor On-Screen Display (OSD) menu.

4. Use the 

 or 

 keys to select 

DISPLAY

 and press the 

ENTER

 key to enter the menu.

5. If you notice a vertical noise (like a curtain effect-shimmering of vertical lines), press the 

 

or 

 keys to select 

Pixel Clock

 and press the 

ENTER

 key. Then press the 

 or 

 keys to 

adjust the monitor until the noise disappears.

6. If you notice a horizontal noise, press the 

 or 

 keys to select 

Phase

 and press the 

ENTER

 key. Then press the 

 or 

 keys to adjust the monitor until the noise disappears.
