I have HDMI ports of both tv and pc and can watch movies from netflix on the tv after plugging in the HDMI cable to the pc and changing the input on the tv menu. Problem is, when I switch the TV back to TV input, the pc doesn't work properly. Do I or can I add the HDMI tv to my device list on the computer? If so, how do I do that? Is this possible to have them constantly connected and just switch back and forth or do I need to literally unplug the HDMI from the PC to use the computer? Thanks for any help you can provide. And do I need a TV tuner for PC? I don't want to watch movies on the PC but would rather have the ability to switch them automatically to the HDTV.
