Issue: Color at sides of screen and "Ripples" on right side of screen.
This is the monitor self test. The monitor is isolated from the PC and shows a green tinge on the left side, and magenta tinge on the right. The right side also shows horizontal "Ripples" moving downwards that the camera could not capture, and is extremely susceptible to screen burn ins. The middle is neutral gray.
This problem appears randomly. It comes and goes randomly, persisting from anywhere from a week to months. If left unplugged for a week or so, the problem seems to go away, but then comes back after a week of being plugged in. An adjacent monitor has been problem free.
Upon closer inspection, every second row of pixels is miscolored, with the ones in between the neutral gray. 
on the right side some of the burn in from an address bar is visible. The rate at which images get burned-in is very fast.
Previously only the right side showed weird color. The left side was completely normal until today. This problem has been occuring since February.
