Experienced problems from the second day (owning it less than 2 months), like stuck pixels, which later disappeared on their own after a couple of weeks, and the main problem of sudden discoloration which manifested once 7 weeks ago, but now it's so strong that i'm going to return the monitor. Discoloration or sudden sponteneous switching to 256-color like gamma (despite that display properties show 32bits albeit with a row of tiled colors instead of smooth spectrum) occurs after a certain interval after power on and strongly correlates with the time off - the longer the monitor rests the longer it works properly. And IT IS monitor problem because i have second one at hand which works OK. BTW, same s... happened when the cable was disconnected...

1-Reset the TV by unplugging its power cord for 30 seconds and plugging it back in. This is an essential troubleshooting tool as a simple reset often will resolve the great majority of technical issues experienced by any kind of TV. Power the TV on after plugging it back in and check the picture for any improvement.
2-Unscrew the coaxial cable that attaches your wall cable outlet to either the coaxial cable input on the plasma TV or to any digital cable converters you may use at home. Check the copper needle in the middle of the cable for any bending or damage and screw the cable back on the coaxial input. Again, check the picture for any improvements.
3-Secure the audio/video connection cables that attach the source device you are trying to watch to the plasma TV. This is a particularly important step if you use component cables. Component cables separate a video signal into different colors, so a damaged or loose component cable can lead to noticeable discoloration on the screen. Once the cables are secure, both in the source device and the plasma TV, check the picture again to see if this may have resolved the issue.
4-Scan your channel lineup and check the other TVs in your home to determine the scope of the problem. If you see the discoloration only on one or a few channels, and the same channels are discolored on the other TVs in your home, you may be part of a cable service outage and you will need to report the issue to your cable provider. If all the channels on the one TV have the same discoloration, and the other TVs in the home look normal, the plasma TV likely will need to be serviced for a problem with its picture components.
The discoloration problem is due to the near by magnetic field appliances like speakers which are very near to monitors ... so what you have to do is just keep some distance to the monitor from the speakers and other magnetic appliances and then press menu button & just give degauss..

Your comp's video card refresh rate (in Hertz, abbreviated Hz) may not be totally compatible with the monitor. Check the properties of your video card, and change the refresh rate (you may have to look around for it) to 60 Hz. This is a pretty standard refresh rate that works with just about every monitor. If it's already there, I'm afraid someone else will have to try and help!
Hope this helps, and please rate my answer, good OR bad.
Dead or stuck pixels are not uncommon in LCD displays, and the less you pay, the more likely it is to happen (as a general rule) Most manufacturers will a dead pixel warranty, ranging from 7 days to lifetime.
Read your warranty carefully, and speak to the place where you bought your display.
