Cheers FB, I'd already sent him most of that,,,, he says he hasn't got any buttons on the monitor ! I was hoping that he could alter it at boot-up, but the screen dosn't stay on long enough to press ReSet Video.
It seems that the monitor declares its-self at 37khz when con to laptop,,, but when he cons to desk-top, it gives warning about 85khz. (Arn't both of these wrong ?)
It's difficult not seeing the thing and trying to put his words over to you guys.
As fruit bat and jimv7 suggest, if he boots up in safe mode this will load a very basic set of VGA drivers which will work with any screen unless its broken. From there he can reset the frequency lower. Changing the frequency doesnt change the screen it changes the frequency that the driver within Windows sends the data out to the screen.
