Self-test

Your monitor provides a self-test feature that allows you to check whether your

monitor is functioning properly. If your monitor and computer are properly

connected but the monitor screen remains dark, run the monitor self-test by

performing the following steps:

Turn off both your computer and the monitor.

Disconnect the video cable from the back of the computer. To ensure

proper Self-Test operation, disconnect all cables from the computer.

Turn on the monitor.

NOTE: A dialog box with text should appear on the screen, indicating

that the monitor is working correctly and it is not receiving a video signal.

When Eco Mode is On

When Eco Mode is Off

NOTE: This dialogue box also appears during normal system operation, if

the video cable is disconnected or damaged.
