What could be causing this?

Hi, this is a problem I've been having for a long while with my video card. My screen randomly started turning red, and eventually my vid card died so I RMA'd it. I thought it was the video card, so after I got a new one back, maybe 1 month later the same thing started happening. The screen keeps going red randomly and I have to shift my desktop left or right for it to become clear again.

Any reason for this or a fix? I don't want to RMA another card 🙁

What kind of monitor do you have? If you have an LCD monitor, especially the old S-IPS types, those have been known to develop weird problems like the entire screen flashing purple or green after a couple of years.

Could be the cable.. is it wedged somewhere? No big speakers near the monitor or anything?

Its either the cable or the monitor itself. If you already replaced the video card and it still does it, you've eliminated that as a possibility.

Verify the VGA or DVI cable isn't wedged or crimped somewhere, or replace it with a new cable from Monoprice or a spare you have.

If you have a CRT monitor, its possible one of your electron guns is dying.

if everything has a red shift, then its the cable -- I bet you are using VGA instead of DVI, right?

Happened to me all the time back in the day -- cept green used to go out so I got a purple screen.

Could be a number of things. I've had a bad VGA cable that did this. I've also had a Princeton monitor that popped loudly and then everything turned purple/magenta regardless of which cable I used. I assume a component failed on one of the monitor's circuit boards.
