You should do the thorough test and leave it on for a while on your brother's computer. If it exhibits the same symptoms, then it's the monitor for sure. If it's new, it should still be under warranty.

Browse All TopicsAfter a good boot full of color and I use my PC for a little while, lately my monitor just starts to fade to a kinda of dull lose of color, kind of purple type of shade. I definitely cant view any greens. It's pretty random when it decides to do this. I will give it a rest and turn the PC off for about an hour. Come back to turn it on and within a half hour its back to the shade of purple. Its not to a point where i cant see anything, just my something wrong with my settings or monitor. I have done these steps...
1. Replaced video card with an equivalent extra I have results in same problem.
2. Plugged in monitor into bros computer, looked great for 5 mins, never tested it for a long duration.
You would think its an internal problem, but my "new" video card responds the same after a while? Must it be a setting? Or even the monitor, which is a fairly new Dell? Thanks for any help.

You said that rebooting the comptuer fixes the problem temporarily, but how about it you just turn off the monitor and turn it back on after a few seconds? If that also fixes it, it's gotta be the monitor. I'm pretty positive it's the monitor, I don't see any way it could be the PC.
But, try this and see what happens to be sure.
This problem will most likely be caused by your monitor heating up. When it gets warm enough the screen will turn different colors. This normally happens if a computer has been on for a very long time (more then a week). Especially when set on the same screen. This is called montior burn. You will have to see if your warrentee is still good or you'll need to get a new monitor. Your monitor will still work but it will have a poor display.

It's almost certainly the monitor. Your troubleshooting eliminated the video card because you changed that out. One other thing to try is after it has been on for a while and goes dull, without unplugging anything, wiggle the data cable (not the power) in back of the monitor and the PC, and see if it has any effect. If it does that's a faulty connection. Also check the data cable pins and make sure none are bent. Although I doubt that's the problem, it never hurts to check.
Either way it sounds like the monitor to me. If it's a fairly new Dell, is it perhaps under warranty?
