Vista 64 Aero problem w/ 3 monitors and 2 video cards

So I just got my new Gateway 30" XHD3000 to go in the middle of my dual 20" Dell 2001FP's and everything is just gorgeous and wonderful, save for one little problem.


I am running Vista Ultimate 64 with a Q6600, 4Gig RAM and an 8800GT for the Gateway and 1 Dell and a 7900GT for the other Dell. Also, I'm using the 169.04 Nvidia driver (for both vid cards).

The monitors are set up like this:

#3(Dell in portrait on 7900GT)---#1 (Gateway on 8800GT port 1)---#2 (Dell in portrait on 8800GT port 2).

Now, before I got the Gateway tonight, I was running Aero w/o problem on both Dell's. But now that I throw a 3rd monitor in the mix on a 2nd video card, monitor in the #3 spot goes haywire. It's getting a signal from the computer, but it's diagonal and completely scrambled.

I have tried "updating my score" (which is 5.7), I have tried both DVI ports on the 7900GT, I have tried switching which monitor is hooked up to 7900GT. Nothing has fixed the problem and I'm beyond frustrated now.

If anyone has encountered the same problem and/or knows of a fix of this, PLEASE let me know.

TIA.

eta: I took a screenshot to try and show what I was talking about, but in the screenshot, the monitor appears just fine.

So I took a photograph of it. Please forgive the cables etc...just set it up to get it working. Not permanent like that ;)


One last edit here...

The 7900GT works fantastically running everything BUT the Aero Theme. Grrrrrrrrr.

This sounds like a driver bug.

Since I do not know of any fix, you should inform the driver team via the driver feedback link on this page.

EDIT:

Given the fact that Aero is being rendered correctly in the screenshot, your problem sounds like the driver is not setting the proper resolution and refresh rate for monitor #3.

Have you tried a different resolution?

I have not, but going to now.


eta:

Ok, native res is 1600x1200 and I tried 1280x800, 1280x768, and 1280x720. All have the same problem.

I should also add that tried using my new Gateway 30" on the 7900GT "slave" video card and the same problem happened.

Again, this is ONLY w/ Aero. All other themes/appearance settings work w/o problem.

I have even uninstalled/cleaned/reinstalled the 169.09 drivers.

I appreciate the input. Please, if you fellas have any other ideas/help, PLEASE lemme know.

I will follow that link and leave this as feedback.

And the hits just keep on coming...


Whenever the/a screensaver pops up, the same "diagonal scramble" pops up and it remains there, even after the other 2 monitors 'wake up' for about 30 seconds, then it pops up and clears itself and is then useable again.

Actually, it appears that anytime anything relating to the desktop changes (wallpaper, screen saver, theme, etc), it goes all haywire and then finally "finds" itself and fixes itself.

Except w/ Aero....
