View Full Version : 6800Ultra - DVI Monitor - Screen flickers, LCD monitor flickers on 1600x1200 on DVI

10-13-06, 02:12 PM
Hi all
I have a Samsung 204B 20'' LCD 1600x1200 (4:3 aspect) monitor and a Gainward geforce 6800 Ultra PCIe.

Any time I try to run 1600x1200 native resolution using a DVI cable, the monitor continually flickers ( blinking ) on and off.
- Using a VGA cable is ok
- Got monitor replaced - same issue
- Was using 21" CRT T- no problem
- Samsung say no known defects with monitor
- Tried beta and latest nVidia drivers

I am looking to see if;

1) anyone else has/has this issue - how they fixed it
2) how can I run my driver in debug mode to see if I can see any bad EDID, etc timings errors?
