Do you see the “Check Signal Cable”
message on screen?
Check the video connection from
the monitor to the computer.
If running Windows and the computer
power is on, reboot the computer and
watch for the initial boot and windows
screen.
If you see the initial screens, then
the image goes dark, the computer
may be set to an incompatible reso-
lution. Reboot the computer in safe
mode and set the resolution and
refresh rate of the graphics card to
a compatible resolution
Do you see the “Not Optimum Mode,
Recommended Mode 1280 x 1024
60 Hz” message?
This message displays when the
signal from the computer exceeds
the maximum resolution and fre-
quency that the monitor can handle.
(> 1280 x 1024 resolution or > 75
Hz refresh rate)
Adjust the computer to a compatible
resolution and refresh rate.
