I have the same problem, where it seems like the monitors won't quit trying to
re-sync so the screen just keeps going black, then back to the desktop, then
black, etc. etc. every few seconds.

This has been happening on my system since Beta 2 and I have an Nvidia
7800GTX card (so not just an ati problem) and my monitors are both Viewsonic
G220fb's.

If I unplug my Viewsonic monitors and plug in a different monitor (an old
Cybervision) things work fine.

I tried contacting Viewsonic to see if maybe they had some sort of updated
driver info for these monitors to run under Vista but was told that it was
Microsoft's responsibility.

So far I have been unable to find a solution anywhere for this problem.

after installing vista 5384 and installing the vista drivers from ATI for the
radeon 9600 the monitor screen flickers every 2-3 seconds, I have tried all
the various refresh rates and resolution settings but the flicker persists, I
have it set up on a dual boot system with XP and everything else seems to
work incredibly well just the screen problem in vista, when I boot to XP the
flicker goes. viewsonic dont seem to have any vista drivers available, anyone
got any ideas on a fix for this?

thanks
