GF3 Ti200 DVI / LCD Problems

[Fuzzb3k]

Aloha...im having a real problem with my new Ti200 card and lcd flatpanel using the DVI interface. The lcd is the Dell 2000FP (20" 1600x1200 native). Apparently the Silicon Image TDMS chip on my Ti200 (Sparkle branded) is capable of UXGA (1600x1200) res. Thats fine in 16-bit mode...but when i increase the colour depth to 32-bit in Windows i get strange artifacts to the left of the screen whenever i move windows around, or to a lesser extent the mouse pointer itself.

Im using the regular Dell DVI cable so its not attenuation of any form i dont think.

The artifacts look something like:

_____________
|.. |
|.... |
|. |
|.. |
|_____________|

(Edit: the diagram above didnt come out right...the |'s should bo in line on the right to form the right hand edge..but you get the idea...)

The (.'s) are the interference/artifact lines which appear along the left edge of the screen whenever a window is dragged about the screen. This ONLY occurs at 1600x1200 @ 32-bit.

Im just wondering if anyone had heard of this problem before, and if so do you have any possible work rounds?

Thanks in advance,

Lee

Hi are you sure that the ti200 can support 1600x1200 via the dvi port? What if you drop to a lower res, do the artifacts go away? I recall reading somewhere that the dvi out of the gf3's only go up to 1280

DVI only supports resolutions up to 1280x1024. see:
