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. The utility is available on the
BenQ website. Follow Step 1 to Step 5 in
Downloading the LCD Monitor driver files from the
Internet on page 9
, and then download the test program auto.exe from
Drivers
to your computer.
1. Run the test program auto.exe. 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.
