Question about ASUS MW221U LCD Monitor
This is an 2 weeks old screen, couple of days after purchase it started
to freeze the picture and then the screen fills with a black color till
its completaly black and usaly some mins later its fine again :S (
sometimes longer hours )
Got dual monitors conected so its not a pc problem defenetly a motitor problem :(
Best thing to do, try a different known working monitor to hook up to the computer. If the screen works and doesn't change colors then you know its the original monitor that is bad.
If you hook up the known working monitor and the same problem happens then you know its the video card that is bad and the video card would have to be replaced.

I'm afraid this looks like an electronic fault. Some component, most likely a capacitor, has degraded, is overheating and going out of spec.
You just might be able to squeeze some more hours of work - but the monitor is still likely to drop dead any moment now - by rigging a computer fan on the backside to extract hot air from the inside.
Possibly, the problem might have a noise factor - try adding a ferrite shielding on the cable (unless one is already there, as it often is) and see whether the thirty minutes' grace period extend somewhat.
A probably unsatisfactory solution might be to drive it at a lower resolution, so that the more relaxed frequency constraints do not stress the component so much.
When the capacitor finally blows, you might be able to recognize it and have it replaced; it's likely a US $1 component and is probably in the LCD driver section. Perhaps, just perhaps, you could already be able to see it with the naked eye looking for a component that looks "wrong" - a small cylinder that looks bloated, with electrolyte leaking, whitish powder around the base, etc. But you would still need some solder work to get it replaced - and, if it's a SMD component, chances are it can't be done at home.
Sorry for the bad news...

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 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.

doremo, Try ATI 5700 card on old Win XP system with Acrobat 9.2 If problem ceases to occur, I would blame Win-7 for your problems!! 12fixlouie

Please check the resolution settings which should be at 1366><768 or 1920><1080. Also check that you have not slected 16:9 aspect ratio accidently. Samir

Try to trouble shoot your video card or unattached your video card from your board and clean the bronze part with a pencil eraser and re attach it again and try if it will work if doesn't the problem is in your video card why because you already used two different type of monitors but still the problem is there..
