OK guys this one is a real stumper. OK ever since I reflashed my bios to "Turbo", I cannot change my resolution past 1280x1024. Anything below "XX" x 1024 works fine, i.e. 1680x1050 and 1920 x 1080 will leave in a black screen. Whereas 1440x900 and 1776x1000 work fine. I am forced to restart my PC once I receive that black screen, almost like it freezes and fails to initialize. I have 8.10 cats installed and tried 2 other known Turbo bios' but they leave my card in nasty vpu recovers, one every 5 mins idling at desktop. I have underclocked the core to see if that could possibly be an issue, did not help. Any ideas? Card games fine @ 850/1150. Idle 37C load 58C with a VF900.
