damn , I loved my nice bios with 1,01V 160/450Mhz and 1,36V 850/1200Mhz...
So i have to take Rivatuner with the 8.11 .

my last 8800GTS was quite easier to handle =/- but i must say, with original bios the 4850 works really fine with the TV.

Thanks 4 help, let me know if there is a solution, please.
