A:Answer The receiver can output to ONE TV via EARC HDMI. You can plug up to FOUR devices into the receiver (game systems, DVD players, etc.) via HDMI and switch input on the receiver rather than your TV.
BUUUUTTT - Unless your TV is capable of receiving an EARC HDMI signal, you won't be able to take advantage of the receivers HDMI inputs. Check your TV and see if one of your HDMI inputs is labeled "EARC." And double BUUUUTTTT - unless you have an HDMI 2.1 compatible TV, you won't be able get video at 4k 120hz / 120 fps.
