OSD Warning Messages

A warning message may appear on the screen indicating that the monitor is out of sync.

Cannot Display This Video Mode

This means that the monitor cannot synchronize with the signal that it is receiving from the computer. Either the
signal is too high or too low for the monitor to use. See Specifications for the Horizontal and Vertical frequency
ranges addressable by this monitor. Recommended mode is 1280 X 1024 @ 60Hz.

NOTE: The floating 'Dell - self-test Feature Check' dialog will appear on-screen if the monitor cannot sense a
video signal.

Occasionally , no warning messag e appears, but the screen is blank. This could al so indicate that the monitor is not
synchronizing with the computer. See Troubleshooting for more information.
