I agree with the person above me. If the resolution or refresh is set too high you can get "out of range" errors, and there will be no picture. If you can set the res to VGA then you should be able to see something. Are you using d-sub as your signal carrier?
thanks for the advice but I tried all resolutions the computer will not keep any res above 1240X10xx
If it is plug and play why doesn't it find the correct resolution?
I don't know what d-sub is so guessing no.
