Thanks for the response. The plasma TV is about 7 years old and 780p (I think) while the projector is 1080p and 4 years old. I assume because of their age hdmi outputs on both are 2.0 or older. I don't have to have both on at the same time. I would have to buy the 976 to see if it resolves my hdmi switching problems and if it doesn't, send it back.
