Troubleshooting

This monitor has been pre-adjusted using factory standard VGA

timings. Due to the output timing differences among various

VGA cards in the market, users may initially experience an

unstable or unclear display whenever a new display mode or new

VGA card is selected.

Note: This monitor supports multiple VGA modes. Refer to the

Preset Display Modes Table for a listing of modes supported by

this monitor.

PROBLEM: Picture is unclear and unstable.

The picture is unclear and unstable, please perform the following

steps :

1. Enter PC to "Shut Down Windows" status while you're in

MS-Windows environment.

2. Check the screen to see if there's any black vertical stripes

appear. If there are, take advantage of the "Clock" function

in OSD menu and adjust (by increment or decrement

numbers) until those bars disappear.

3. Move to "Phase" function in OSD menu again and adjust the

monitor screen to its most clear display.

4. Click "No" on "Shut Down Windows" and back to the

normal PC operating environment.
