19 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
Adjust
function. Go to Auto Adjust 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. 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 13, 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 AUTO key on the monitor.
3. Press the ENTER key to access the monitor On-Screen Display (OSD) menu.
4. Go to Geometry.
5. 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.
6. If you notice a horizontal noise, select Phase and adjust the monitor until the noise
disappears.
Adjusting display mode
To display images of aspect ratio other than 16:9 and size other than the panel size of your
purchased model, you can adjust the display mode on the monitor.
1. Press the
ENTER key to access the monitor On-Screen Display (OSD) menu.
2. Go to
Miscellaneous 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) cable to your monitor, the Auto Adjust 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 Adjust function.
