i have an asus z77 sabretooth with msi gtx 760 nf 2gb / oc graphics card.
my monitor is a sceptre naga x42 - kinda old but still a good hd unit.
i use the hdmi port coming from the grapics card to the hdmi port of the monitor - using
just a straight hdmi cable.
this has been working great. until i updated the nvidia drivers to 331.65.
now, the monitor works only when posting, and i can also see "starting widows",
but after that just a black screen.
so i attached a different monitor to the dvi port and i can see windows.
i tried then hooking up the hdmi cable, and the sceptre just won't show up in nvidia control panel or device manager.
i also have a dvi-to-hdmi cable and tried that out of the dvi port from the graphics card - same thing.
i can confirm that the straight hdmi cable and dvi-hdmi cable are in sound working order.
i's love to uninstall / re-install the old nvidia drivers that were working, but i
neglected to take note of which versino they were! i thought maybe it was the ones on the
install disk that came with the graphics card, nothing.
I am having the exact same problem. Only thing is i cannot revert back to an older driver because it i do. Most of my games no longer work. I have a DVI to HDMI cable but that has never really worked at all. So I am stuck with one monitor currently with no fix avail.
