sporadic black screen flicker on new U2711
My new U2711 arrived from dell yesterday. I unpacked it, and hooked it up to my Dell E4310 (w/ the docking station) using the DP cable. The image is perfect, but the monitor sporadically flickers to a black screen for about 1 second (every 10 minutes or so). I've checked the cables and latest graphics drivers; all of these look fine.
Any ideas? Is there something else that i need to configure on the monitor/computer to prevent this flicker?
In another setup, the exact same laptop drives dual dell 24" monitors (using two DP cables /docking station) w/o any problems.
Is this a monitor fault/failure?
Thanks,

Same Problem here, every 10-15 min for 2 Sec. black screen :-(
E4310 / U2711 I cannot use the Monitor without a Dockingstation, because no Digital Output on the Laptop only VGA

So your laptop has Windows 7 using the onboard Mobile Intel GMA X4500 Graphics Controller?

What resolution is the laptop sending through the Dock Display Port? When the monitor is connected, press the monitor OSD Menu button. The bottom of that screen should state what resolution the monitor is getting from the laptop. 2560x1440 is the monitor DP (Display Port) default.

Yes Windows 7 / x64 with Intel HD Graphics (there is no other option on the E4310)

Same Problem with two other dockingstations (E-Port & Advanced E-Port), a Eizo 23" Display works well.

I'm having the same issue as well. Here's what's interesting though: I have one monitor hooked up via a VGA cable to a Samsung Syncmaster 204B, and a second monitor hooked up via DVI to another of the same monitor.
The VGA-connected monitor works just fine. However, the DVI monitor only when I reduce the resolution from 1600x1200 to 1280x1024. So there seems to be an issue with the DVI connection and/or Intel drivers at that resolution.
The monitors themselves are just fine. I also used this setup with my ThinkPad T60 for 3 years with no issue.

Please test the monitor without the dock.
