OK, so it's technically more of an audio question, but it's my first time using ARC, HDMI-CEC and a receiver. I just bought a Samsung Q70R and a Onkyo-NR868. My original plan was to wall mount the TV and just run one HDMI cable through the wall from the ARC HDMI port into the receiver and do all of my input switching via the receiver. However, now that I have it set up that way, I'm not liking the fact that since everything goes into one HDMI port on the TV, I have to adjust picture settings/game mode depending on what I'm playing/watching. So... would I be missing out on anything if I put my most used devices on HDMI 1, 2, and 3 on the TV, and just left the HDMI 4 solely for the audio via ARC and not actually carrying any video? Or is there a simpler way to save different image settings for different devices using just the ARC input on my TV? Before I call a friend to help me remove my TV from the wall mount I want to make sure I have the right plan in place to get the perfect picture settings for each device and still be able to use my receiver for the audio. Sorry if it is a dumb question or explained poorly, I figured I would try to learn as I go with setting up my first receiver and slowly build up from a 2.1 setup, but I think I'm in over my head at the moment.
