After minimizing a game, my monitor went dark and the color looks
weird. I have restarted my computer - I also did a system restore to
the day before. I went into the display properties and i changed the
contrast / brightness / gamma and got it to look decent on the desktop,
but the game still looks so dark, and the games display settings have
never been changed before. They did not change, but i did mess with
them, and the game still looked like ****. I don't know what to do now.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
Disconnected Data cable from the monitor to the back of the CPU. Do a self test on monitor if u get colors on the monitor it is working fine.
check for loose cables. Try to do factory reset on monitor using buttons on monitor.
hello! it would be good if you will inform the company wherein you had puirchase that gadget right away. there might be some technical problem with it. companies always provide a warranty, you consult it to them right away..thanks! feel free to contact me for more inquiry.
We have about 20 of these at work. Four of them went dark, to varying degrees, in the two years they were covered by warrantee, and were sent back to the factory for repairs. Since then, eleven more have gone dark. I finally got around to looking at them a few days ago. I have repaired five so far, and in every case it has been the same cause. The capacitors on the inverter board are burning out. There are two 470uF, two 1500uF and a 1000uF that are not holding up. Costs about 4 bucks for replacement parts at digikey; qtys and Part numbers are: 2 PN #493-1561-ND 1 PN #565-1664-ND 2 PN #P13124-ND It takes about an hour, and minimal skill with a soldering iron to fix.
have you checked your PC output?
check it with another screen (whichever)
and see if the output signal is good
if soo check the cable and connections to your LCD
check your PC for software configuraitions:
1) TV output
2) good resoulotion
3) media borad is strong enough to handle this LCD
if all is good then maybe the TV borad is sending a low voltage/current then the LCD can see
