Re: URGENT! 7600CS (rev 02e1) stays black when screen via VGA extender
The steps you've outlined are only expected to work if the mode that the driver is being instructed to use for your display is valid for your display *AND* there is no signal lost. You cannot ignore the influence that your KVM, DISPLAYS; DVI/VGA etc have on the problem you're reporting.
As I stated earlier, the problem you're reporting sounds very much like a hardware limitation, especially since its specific to G7x based cards.
