Hi. I've banged my head against this one for a few days and I'm about to give up. Any help greatly appreciated.
Fedora 17. Nvidia geforce 210 which has VGA, DVI and HDMI outputs in a Dell Optiplex 755. Using latest nvidia driver (310.19). The VGA port works fine. I can connect the DVI port to a TV and nvidia-settings will show that the TV is detected. When I try to connect to the same TV using the HDMI port, the TV isn't detected. It isn't a bad cable because I can use the same cable to drive the TV from a Windows laptop.
xrandr would seem to indicate that the system knows that there is an HDMI port. There seems to be a driver loaded for the audio over HDMI too. I've tried about everything I can find on the net but any and all suggestions appreciated. I'll try them all.
