LCD Color Corrector?

colorContrast asks: " I've currently got a Viewsonic VG700b, and as of recent, it has been giving me some trouble. Instead of showing real black, i'm now getting a red hue for black, and the pixels on the screen have become more pronounced than they used to be. The odd thing is that when I brought my monitor home over vacation, the problem was fixed for a short while, but now it appears to be broken again. Does anyone have any suggestions on if its time to get a new LCD, or if they know of a fix for this problem? (I have attempted to manually correct it by changing the colors but that did little.)"
