troubles with SLI

I am sure other people are having this problem and have read about it on other forums, but I was wondering if any of you guys here had any ideas.

I have 2 XFX Geforce 6800GTs. I am currently playing Far Cry with latest patch I think 1.31, UT2004 with latest patch, and Doom 3. Far Cry is great at my native res of 1680x1050 but Doom 3 won't even load with that res and in UT2004, the screen shakes around 10-20 pixels lines vertically. I have tried all sorts of drivers including the newer betas. The one conclusion I have come to is that it has something to do with the DVI interface of my lcd monitor. When using analog, I don't receive the shaking of the screen but it constantly does an "auto adjust" every time I do anything graphically intensive.

Here is the forum over at nvidia: Screen Shakes SLI

If any of you are having similar issues, have you resolved anything or found ways around it? One other miscellaneous thing if anyone can help with is creating custom resolutions in doom3 or ut2004, the possible resolutions jumps from 1280x1024 to 1680x1024. in benchmarks 1600x1200 runs great and utilizing SLI works wonders on rendering but I don't have 1600x1200 as an option in the games.

Any help with resolving my screen shaking problem is greatly appreciated.
 
Have you tried the latest 71.84 betas? Not sure if they help but worth a shot if you have not tried them yet.
 
I am having a problem too with wobbly / shaky video. I have 2 BFG 6600GT OC cards on the Asus a8n sli dlx. I only have a CRT ViewSonic A90f+ monitor right now which has no DVI input but my video cards each have 2 DVI out ports only. So i had to use the little DVI -> VGA adapter plug. Whenever I jack the resolution above 11x8@75Hz, the screen wobbles and shakes back and forth. Doesn't matter if I'm in a game or just on my windows desktop. Reducing the refresh rate diminishes the wobbling but it does not go away totally. I can't stand looking at a monitor below 75Hz because I definitely see the flicker and it drives me nuts. I was hoping I could buy a new LCD monitor with DVI in and get rid of this problem so i can use higher resolution but looks like my monitor might not be the problem after all after reading those other posts from your link.
 
This seems to be an issue with widescreen resolutions + DVI + LCD combonations as I have a CRT running at 16:10 res's and all is good. You could try the new drivers released today and/or use the analog connection on your monitor.
