I could get another box to plug into the other HDMI input and switch over to it when I want to watch HDR, but that seems silly to need to do since I don't know when Netflix content will be HDR and when it won't be
I'm able to get HDR to work on all of my connected devices. With the Xbox One X, there's a specific set up in order for HDR to work which requires a different wiring set up for HDMI and Audio Return from the TV. With the Shield and Oppo 203, all audio is routed to my AVR first.
The issue I was having is being able to set my Display to a specific video mode. I wanted my Xbox One to be set to "Game Mode", while my Shield/Oppo 203 set to "Custom". Using just one HDMI Output on my AVR directly to the TV would not accomplish this unless I created some time-consuming configurations with my Harmony Remote for each device.
By using the separate HDMI Outputs on my AVR, I can connect one cable to HDMI 2 for my Shield and Oppo, and one connection to HDMI 3/Arc on the display for the Xbox. This will allow for separate Video modes on the TV.
Also, in my case, with CEC enabled, whenever I would turn on the Shield or Oppo 203, the display would automatically change from HDMI 2 to HDMI 3/Arc, and I would have to manually set the TV back to HDMI 2. Also, with the connection moving to HDMI 3/ARC, the video settings for my Shield and Oppo 203 were not correct and over-saturated.
With CEC disabled, the display connects to the correct HDMI Connection, and thus the proper video settings for each device are now displayed.
