Re: 7600 GT problems with dual link 2560x1600
for the record, this one was/is a hardware problem. I replaced the cable, used a different port on the video card, and used a different port on the monitor. worked without a hitch. this means the problem was hardware, though I am not sure yet what is to blame.
sorry to have driven everyone up the wall with this one. and thanks a lot for your help.
