In my bedroom I got a Blu-Ray Player, a HTPC, my Soundbar uses one with ARC my Playstation TV uses one, my PS3 uses one My cable box uses one my Xbox 360 uses one. My soundbar has 3 HDMI ports on it so the one it takes gives me 3 back so I have a total of 6 HDMI ports and I use the all.
2 HDMI ports is a joke. The only time I switch devices is if I move my PS4 or Xbox One in the bedroom then I unplug my PS3 or Xbox 360. Now in the living room I have a 8 HDMI in 2 HDMI out av system but out of my 3 main TVs none of them have don't have 4 ports on them.
