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 and the power indicator is blinking, run the monitor self-test by
performing the following steps:
Turn off both your computer and the monitor.
Unplug the video cable from the back of the computer.
Turn on the monitor.
If the monitor is functioning properly, you will see a white box
with a red border and inside as shown in the following illustration:
The three boxes inside the border are red, green and blue. Failure
of any of the boxes to appear indicates a problem with your
monitor. This box also appears during normal operation if the
video cable becomes disconnected or damaged.
Turn off your monitor and reconnect the video cable; then turn on
both your computer and the monitor.
If your monitor screen remains blank after using the previous
procedure, check your video controller and computer system;
your monitor is functioning properly.

Warm-up Time

All monitors need time to become thermally stable the first time you
turn them on each day. Therefore, to achieve more accurate
adjustments for parameters, allow the monitor to warm (be on) for at
least 30 minutes before making any screen adjustments.
