That can be due to bad DC filter caps in the power supply, worst case will be the lamp assemblies.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), 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 SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Resolution and refresh rate


1280x1024 native and will go to 75hz x 81khz
I'd probably look more at what your video card supports.

OK, I've figured it out! There's something wrong with the control chip, so if you don't have it under warranty, here's what you can do:
1. Turn off the monitor
2. Unscrew the face of the monitor
3. Remove the bottom part of the face from the backside, so you can see the chip
(the control chip is located on the face of the monitor, under the buttons)
4. You will see a small white connector about 5mm wide, UNPLUGG it
5. Put the small cable that you've unconnected under the front, so you can close the monitor back
6. Close the monitor and plug it back in

That's it. You won't be able to change your settings (they autoadjust anyway), but you won't have to throw the monitor away!

Peace.
