I tried it, but it doesn't work when you add more than 1 resolution, if I add 1024x768 and 800x600, for example, the only available resolution will be 800x600. There must be a way to do it properly...
i added the 1024,768 on all of the folders from 0000 to 0011 because it wouldn't work on 0000, i dunno which one it worked on so i added it on all of them and then i was able to get the 75Hz but then the sound kept messin up, everything was in slow mo, so i deleted it on back to 60Hz again :-(
If I use rivatuner, I don't know why but the dualview (clone) of my GF4 doesn't work anymore, probably because the TV-out needs the 60hz, but it's disabled. ReForce works fine.
Please choose better words next time.
