LCD monitor screen blue

Either the VGA card or the monitor can not display the resolution correctly, so you need to get it back to where it was, this solution is for Windows users (not sure about other OSs), reboot your system and and get in the options start-up screen by pressing F8 at boot, choose safe-mode with VGA, if you see your desktop normally here then it's definately the screen resolution, set it back to a lower resolution (try 1024X768 and go downwards until it works fine), restart your system normally and you should be able to test new resolutions again, if it won't work using VGA mode then you might need to uninstall your VGA card but make sure that you have the correct driver for it before uninstalling, also please disable any onboard graphics card if you have one.

I hope this would solve your problem, please feel free to ask if you any further questions regarding this matter.

Thanks

I had posted my problem in 2006. Everything is fine now, thanks. The problem was with the connectors behind the monitor. I think they were not fixed properly. Strange that it was such a minor thing --- :) Thanks everyone for your help.

I got a KDS Visual Sensations 190is monitor hooked up to my computer with win 98 and Nvidia with latest driver...got the blue screen too. Reinstalling video made it clearer, but still no red or green color just all blue, so what did you do..........

Other than hardware problems, the shake u mentioned might be due to magnetic interference. make sure any adapters for speakers or modem are kept in a place not nearer to the monitor
