The video is distorted.
Probable Cause Solution
The monitor’s controls
are not properly
adjusted.
Adjust the monitor controls until the text
becomes clear. (See your monitor

Check the connector and cable for bent or
damaged pins.
The surge protector or
UPS is damaged.
Disconnect the monitor power cable and
connect it directly to the power source.
The monitor is too
close to a source of
electrical interference.
Move the monitor away from sources of
electrical interference, such as televisions,
unshielded speakers, microwaves, fluorescent
lights, and metal beams or shelves.
The monitor needs to
be degaussed.
Turn off the computer and monitor and leave
them off for at least a half hour, and then
restart the system.
