The discoloration indicates you are missing one of the three color bands (magenta, cyan and yellow). Likely the display cable from your computer to monitor has a slight break in one of the interior wires.
Slowly move the cable around near the connectors and observe the picture. If you see it change, replace the cable. You can get one from any computer store for about $10-$15.
