Sparkling 2D pixels (NVidia)

[Cat]

Has anyone ever had pixels in a picture start to exhibit Christmas light behavior? Turning off, kinda crawling, etc. It was happening last night on some large pictures, and it seemed to be localized to darker colors. Using both IE and Opera would generate the same behaviour, but these were jpegs.. Set my GF4 to default speeds, and had the same result. I'm not too concerned, because it's not happening right now, but I haven't found the pics that were causing the problem again. I'll look sometime tonight.

Anyway, if someone has seen something like this before, please tell me. Thanks.

Try changing the resolution and refresh rate and make sure your VGA cable is plugged in tightly.

Also you might've fried the card from overclocking.

It's strange though; if I scroll the picture up and down, the affected pixels scroll with it..

hmm, i don't know but from the sound of it, maybe you have some type of overlay type thing going on. for expample, winamp has visualizations and you have an option to use overlays that substitute a cetain color to the visualization, a use for this would be you can set it to your desktop color and have a fullscreen visualization background. maybe your have a dvd decoder card? those use that type of feature... sounds really odd... i would try lowering your speeds of your gpu and or memory and see what happens. good luck

I get this same problem ( red and blue sparkles in videos, etc.) when I overclock my memory past the "motherboard rated" 266 speed (3:4 ratio @ 133FSB, = 356) , sparkles go away when I reset to 1:1 ratio (266).

El Norm wins! 😉 It was DScaler (TV tuner software) using the overlay. I almost always have it open, even if I'm not watching TV. I guess I just forgot about it.
