Picture optimization
7. Picture optimization
The easiest way to obtain an optimal display from an analog (D-Sub) input is to use the
i
key
function. Press the
i
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 (1680 x 1050) when you use the
i
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
i
key on the monitor.
3. Press the MENU key to access the monitor On-Screen Display (OSD) menu.
4. Use the
t
or
u
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
t
or
u
keys to select Pixel Clock and press the ENTER key. Then press the
t
or
u
keys to
adjust the monitor until the noise disappears.
6. If you notice a horizontal noise, press the
t
or
u
keys to select Phase and press the ENTER
key. Then press the
t
or
u
keys adjust the monitor until the noise disappears.
