Hi
I bought two DELL U2711. But i got the same problems as shown here:
Sometimes it disappears for minutes - but when it flickers - also the OSD flickers 
I used the shipped DELL cables - are they of bad quality? Or is the display broken?
The next problem is, that i cant use both with my PNY Quadro FX370. 1 monitor works - the second claims to get wrong signals :-/ But if one works - the other should also do right?
Thanks a lot!!!!
Michael
