Default Re: 1080i

Ok, I'm having the exact same issue. I had a 7600GS which I got working, primarily with NoVertRefreshCheck set. I put in an 8500GT and no matter what other options I set nor what mode I try using, my Sony 1080i Tv won't sync over DVI. Without NoVertRefreshCheck, nothing above 720p gets validated.

I've seen many people discussing this issue and I've seen a few driver versions come out since the original report but I haven't seen much response from NVidia on the issue. I'm getting a tad discouraged.

EDIT: Ok, I managed to get a working 1080i mode. My modeline:

ModeLine        "myATSC-1080-60i" 74.24 1920 1960 2016 2200 1080 1084 1094 1125 Interlace +hsync +vsync
And the options necessary:

        Option          "ModeValidation" "NoDFPNativeResolutionCheck"
        Option          "ExactModeTimingsDVI" "True"
