I just bought a dell 3007 wfp-hc monitor to go along with a older dell 20" and am using them both with radeon x1950 pro pci-e card. The 30" is a refurb monitor and is having this weird flikering of many pixels, usually green, but sometimes red and blue on black backgrounds. So far there seems to be no issues in games, the only time it shows up is when i have a dark desktop background image. The pure black desktop with no image has no issues. Also the problem seems to go away after ive been using the computer for a while. Is this a monitor issue or a video card issue? I have had no problems using the card for the past 2 years running dual 20" screens, but i also think that these dell refurbs are checked to make sure they work.

Did you try the Refurb in both Monitor Ports on the video card? Are the Specs on both Monitors Compatible. Possibly an updated driver for card or Monitors? What happens if you run One Monitor at a time? There is nothing to learn from someone who already agrees with you.

If i run the 30" by itself it still has the problem. Also tried both dvi ports and it didnt change anything. I have all of the newest drivers. The vid card does support 2560x1600. When running at lower than max resolution the flickering goes away. And when i change it from 32 to 16 bit colors almost all of the flickering goes away except a few pixels.

I have the same problem with my 3007WFP (not HC). Did you managed to fix it ? It seems that my monitor have this issues with LCD itself, the problem is not with drivers, graphics card, cable etc. When i disconnect DVI cable from monitor, monitor starts standby procedure in which monitor turn colors from white, grey red, orange etc. up to black. And only in black there red, green pixels can be spotted.

I'm sure Dell checks the refurb gear to insure it works but, return it for a replacement or refund...they could have missed something. You gave all the clues that it's just not up to snuff. Skip
