Another question since I'm new to the newer features and connections. With having a 1080p tv and later a getting a 4k...right now all my hdmi's (dtv, Blu Ray, fire TV) are connected to the HDMI input on the TV so signal goes to the tv and I have an optical out to the receiver for audio. With a new receiver, say Denon, do I connect all my hdmi's to the receiver instead of the tv and HDMI out from the receiver to the tvs ARC hdmi and the Denon will do all the video switching? Once upgraded to a 4k the same configuration?
