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.)"
It could also be your VGA card. I have seen VGA boards go bad in such manners that the make darkened streaks across the screen, off color to complete wrong or missing colors and artifacting/flickering picture. Monitors sometimes go bad in the exact same way! I've been fooled into thinking a display was bad before.
Also, this is a very slight possibility, but your VGA cable might be bad. If the cable is crimpled or damaged, there may be cross talk among the signal wires. This usually leads to a ghosted image, but may cause color problems.
So, I'd check your display out on a different PC, with a new cable just to rule out those issues before buying a costly replacement. The case is probably going to be that your display is just bad. Viewsonic isn't a great name in monitors, but then again no one makes a good display anymore.
As a long shot, but Windows and Mac OS X support color profiles. You might be able to compensate with software depending on your video card. I'm pretty sure X.org has some sort of color profile support, though I may be wrong on that point.
