Troubleshooting
This LCD monitor comes pre-adjusted with standard VGA timing. Due to output
timing differences among various VGA cards, you may initially experience an
unstable or unclear display when a new display mode or new VGA card is
selected.
Before applying any of the following troubleshooting procedures, you should first
apply the Auto Adjust option in the OSD menu.
Problem Possible
solutions
Display is unclear
and unstable
To stabilize and clarify your display, open the OSD and adjust
the clock and phase to obtain a clear display or change the
resolution to the display’s optimal setting 1920 x 1080 at 60hz.
Make sure you use auto adjust function after changing the
resolution.
There is no LCD
display
If there is no display on the LCD, refer to the following:
1. Make sure that the power indicator on the LCD monitor is
lit, that all connections are secure, and that the system is
running on the correct timing. Refer to Appendix B for
information on timing.
2. Turn off the LCD monitor and then turn it back on again.
Press the OSD Menu button (refer to OSD Menu page 9)
once and then press one of the Adjustment Control buttons
several times. If there is still no display, press the other
Adjustment Control button several times.
3. If step 2 does not work, connect your PC system to another
external CRT. If your PC system functions properly with
a CRT monitor but it does not function with the LCD
monitor, and the LCD monitor’s power LED is blinking,
the output timing of the PC’s VGA card may be out of the
LCD’s synchronous range. Change to one of the alternate
modes listed in Appendix B, or replace the VGA card and
repeat steps 1 and 2.
4. If the power LED is not lit, check that the AC power
connector is securely connected, and verify that the AC
adapter LED is lit. If the AC adapter LED is not lit, please
contact your dealer for assistance.
