JD,
We have Vsynch working correctly on an Alienware AW3210 LCD (a gaming monitor)
at full 1080Px120Hz. But are you using a DVI, VGA or HDMI cable drive from your
card? The biggest problem I'm having with several different computers has been
getting the driver to communicate with the display correctly through the dual-
link DVI cable that you need as a minimum. Apparently, the newer displayport
standard may fix these issues, but few cards have native support for it yet, and
most monitors don't either. I've no experience with driving a display via HDMI,
but that could be worth looking into.
