Greetings, if you recall I had a previous post about my 7.1 catalyst drivers. This is just a follow-up. The problem, I have found, is that most new games/programs which I have set at high resolutions, and automatically adjust their refresh rate accordingly, have a black screen upon booting them up, and that continues until I forcefully go back to the desktop. The maximum amount refresh rate I can go to is 60 Hz. My monitor is not the problem, as this was not happening beforehand. I do not know if it is truly a refresh rate problem, or something else in the programming, but I do need assistance. I am very confident that the problem is software, not hardware, for I was using 6.2 drivers a while back, and they functioned perfectly at 75 Hz, and had no real problems. Please help. I don't know what to do, other than roll back my drivers to Catalyst 6.2, but my rig seems to function faster under 7.1, and I want to see if I can keep it at that level. My card is a X850XT 256MB AGP.
