Troubleshooting

CAUTION: This product supports multiple VGA modes. This flat-panel monitor is pre-adjusted

in the factory with standard VGA timings. Due to output timing difference among various VGA

cards in the market, you may initially experience an unstable or unclear display when a new display

mode or new VGA card is selected.

CAUTION: Display optimization can not be assured if the mode chosen is not supported in the

list.

CAUTION: If the video signal passes through an interface device when the signal is sent to the

monitor, that device may limit the available video modes.

If the display is unclear or unstable, use the following procedure to achieve the best flat panel

performance for systems running a Microsoft® Windows® operating system:

1Enter the initial step to shutdown the operating system by clicking the Start button and then clicking

Shut Down.

2If any "black noise" vertical stripes appear, use the Clock function in the OSD menu to adjust

display until those bars disappear.

3Use the Phase function to adjust the monitor screen.

4Click No on Shut Down Windows to return to the normal operating system environment.

You can also use the Auto Adjustment function to adjust the flat panel monitor. Reference "Adjusting the

Monitor Display" section on page 1-10.

If there is no display on the flat-panel monitor, use the following procedure:

1Make sure the power indicator is illuminated, all connections are secured, and the system is

operating on a supported timing. See "Specifications" section for more information.

2Turn off the flat-panel monitor and then turn it on again. Press the or function button

and then press either or adjustment button several times.

3If step 2 does not work, connect your system with another external monitor (either CRT or flat-

panel monitor). If your system is operating and functioning properly with the external monitor, the

output timing of the VGA card may be out of flat-panel monitor’s synchronous range. Try to

change to a supported timing listed in "Specifications" section or replace the VGA card and then

repeat steps 1 and 2.

4If the above steps do not correct the issue, please contact the manufacturer for assistance.

If you choose an output timing that is outside the synchronous range of the flat panel monitor, the OSD

displays an "Input Signal Out of Range" message. Choose another mode that is supported by the flat

panel monitor. See the "Specifications" section for information on timing.

Please check the video cable connection to the host system.
