No HDMI Signal
I have a PC running win 7 64 with an Ati R7 260X through a JVC X70 projector...HDMI always worked fine but gamma and colors were way off so I started messing with some settings one of which was Virtual Super Resolution checkbox...Input signal went blank and would not come back. I plugged in a normal LCD monitor and worked fine...Decided to switch to my old nvidia gt460..installed newest drivers and now I have a signal on the projector up until the windows logo finishes then it goes blank and all i see is a vertical colored bar..the color changes after each boot. Again the pc works fine through my lcd monitor but not the projector. I have tried resetting the projector, switching from RGB to 4:2:2, reinstalling drivers, replacing HDMI no luck. Any ideas?
