Recently my screen started to vibrate at a high frequency, and at first I thought it had been on too long, and discovered that turning it off for a bit would usually fix the problem. It got more and more frequent over a few weeks, and today when I turned it on the screen had a greenish hue. The colors, after a few seconds, appeared to be going back to normal, but got brighter than they're supposed to be. I checked and saw that the brightness and contrast controls were on the normal setting. Then the screen blinked off and on once, and a few seconds later completely shut itself off for a few seconds before coming back on by itself. Perplexed, I turned it off manually for a few minutes. When I turned it back on, the screen had a magenta-like hue. I left for a minute and came back to a purplish screen, which upon typing this has gone to a bluish purple.
So... what type of monitor should I get to replace this one? I don't have enough money for a flatscreen, though I don't really want one anyway. My dad ssuggested getting a ViewSonic.
