I read something similar somewhere, I did google my problem before posting.
Unfortunately I have a clean install of win 7 and the only drivers I ever had on this comp are the 275.33. Even so, my TV got here a bit late, so I did have only my vga monitor at first.
So I uninstall the drivers and followed the advice I found there- connect dvi monitor only, install the drivers, reconect vga monitor= profit. I say unfortunately as I'm still in phase 2=?...
Thank you for a probable solution. I guess my luck had to run out eventually, as I did get a full hd dirt cheap new 42" that has so good picture it can actually sub my main monitor
