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. 
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 
 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 
 keys to select Pixel Clock and press the ENTER key. Then press the 
 keys to 
adjust the monitor until the noise disappears.
6. If you notice a horizontal noise, press the 
 keys to select Phase and press the ENTER 
key. Then press the 
 keys to adjust the monitor until the noise disappears.
