Contour 2 / Pace XiD HDMI handshake issues?

When you boot your equipment, all connected devices perform a "handshake" via HDMI for a who's who. If Contour is connected to your AVR, Contour detects the AVR as an audio-only device. Disconnecting and reconnecting probably re-initiates the handshake. It works but after some finagling...sometimes.
It could be a glitch in the AVR, so I'd check for any updates to its firmware.
It appears HDMI-1 on the rear the Denon is only for cable/satellite TV.
If you have HDMI-CEC enabled on your setup for Contour, disable it because Contour...as far as I know...doesn't support it. LG calls HDMI-CEC SimpLink.
Why not just connect Contour to your TV? CATV signals are so heavily compressed, an AVR won't be able to improve it.
I've already updated firmware for the AVR and TV. The Contour box is also connected to the HDMI input on the AVR that is labelled "CBL/SAT".
I have the AVR in use as sort of a hub that all of my sources connect to so that only a single cable goes to the wall-mounted TV. It's one of Denon's 2020 HDMI 2.1 / 8K compatible models. I have all video and image processing in the AVR turned off because the TV does a better job of that anyway.
