I have a started an informal poll of users with the Radeon HD 5000 series graphics card installed on their system here in our forums to help me diagnose a potential issue.  The area we are focusing on is monitor/display noise in both 3D and Windows mode of the graphics card with varying monitors, etc.

This example is something we saw in our recent Radeon HD 5670 testing – this was by far the worst it ever got and it ranged from being perfect to this at random instances.  I have also seen this happen on my system at home with the Radeon HD 5870 installed, but to a lesser degree.  Both systems were using a dual-link DVI output on a 30″ monitor (one from Apple, one from Dell) and it occurred at both resolutions of 1920×1200 and 2560×1600. 

If you have seen anything like this, or have NOT seen anything for that matter, please stop by this thread in our forums to discuss and leave your input.  Thanks!
