I bought x2301 about 4 months ago and since day one, it flickers whenever there's a chunk of light grey color displayed on screen. It gets even more obvious when I go from grey background to white background.
It's connected via DVI to NVIDIA GeForce 7300 LE and have the latest driver for both monitor and graphic card on Win7 SP1 x64. The same config works fine with my other Dell monitor. The monitor is on factory setting, running 1920x1080 @ 60Hz on 32-bit color. It's a single monitor setup. I would have tried other resolutions but the monitor doesn't seem to support any lower resolutions (and I wouldn't call it a solution to my problem anyway).
Any idea? I'm seriously considering RMA now. Thank you.
