the way I have it setup:
the monitor is connected to the geforce via dvi cable
the TV=samsung is connected to the geforce via hdmi
I use the nvidia control panel, it recognizes the samsung, I enable it, hit apply, the samsung reads no signal
I take out the dvi cable, leave only the hdmi to tv connected, power comp on it boots up just fine, im able to get a display. I connect the monitor, the screen goes black on the tv, the monitor reads no signal.
I tested with two different hdmi cords both does not work. the hdmi cords I tested works on different devices (xbox,ps3)
I rolled back the device driver update for the graphic card same issue occurs, tv reads no signal with both hdmi and dvi connected
