From: Buck Turgidson on
I have an NVIDIA GE Force 6600 card with 128MB of memory. When I run WMC in
full-screen mode, I get dots and vertical lines in the screen. I wouldn't
call it pixelation, but it certainly looks like some kind of interference.

At first I thought it may have been heat-related. I re-arranged the video
card so that it has maximum ventilation.

Then I discovered that it works fine if I window-ize WMC.

Is there something about full-screen mode that changes the card
configuration?

Any idea, short of a new card, how to resolve it?

Thanks for any help.

If it doesn't happen in 2D desktop or 3D gaming tests, try a
different driver... especially if you are using a driver
included with the card instead of a recent one from nVidia's
website.

Are you using one of the preset resolutions that match your monitor's
preset resolutions?
