Display corruption

[donsopp]

Hi

I have recently upgraded to an ABIT KT7a board with ATI Rage/Xprt2000 video card and Iiyama S900MT1 monitor. My problem is that the display onscreen keeps corrupting - a pattern of regular dots appears and makes screen unreadable. Is this a sync problem? I have downloaded the latest drivers from ATI

Does this happen at all resolutions or just certain resloutions/refresh rates?

You might be using a refresh/resolution combination that the monitor and/or vid card just don't like for some reason.

Have checked the technical data for the monitor and ATI card. Card is capable of 32 bit 3D graphics up to 1920 x 1200 (based on data at ATI site) and 2D graphics at 1600 x 1200 @ 85Hz. The monitor gives max resolution as 1600 x 1200 @ 75 Hz and operation at 1280 x 1024 @85 Hz. This morning I have set the parameters to be 1280 x 1024 and changed the refresh on the card from optimal to 85Hz. I will see if this makes any difference and I can say that the corruption has just occurred and again it is like a regular grid of spots more intense in some areas of the screen than on others and these more intense areas move about as I type (which is probably irrelevant). Wonder should I try a different graphics card?

Try 1024x768 @ 75 Hz for troubleshooting purposes - and try *different* ATI drivers - the newest aren't always the best. Have you installed the Via 4 in 1 motherboard drivers?
