in the HTPC forum in hopes someone can assist with my situation:
My setup in in my sig, but to recap my Shield TV runs into a Denon X2200W AVR with full HDCP 2.2 support on all jacks into a 2015 Vizio M60-C3 with HDCP 2.2 on HDMI1, 2 and 5 (IIRC), the last being 60Hz while the rest are 30Hz.
The Netflix app on the Shield militantly refuses to provide UltraHD 4K unless I connect the AVR to the Vizio's HDMI5 port and reboot the Shield. After returning the cable to HDMI1 - which I need to do to access the TV's Amazon and Vudu apps (why are there no Android TV versions of either?) and get ARC for OTA TV - I will still have access to 4K titles but after a couple of days it will degrade to having a 4K row in the menu, but every show's listening only offers HD, and then the row goes away. Running the test pattern loop (with little Asian girl and crayons in middle) never goes past 1080p.
I went and bought a new AVR (which led to new speakers) solely to save having to switch devices when I wanted to watch 4K Netflix and my old (because 2013 is old) Sony with 4K passthru was only HDCP 2.0, but this inability to get 4K unless I mess around with things is a PITA having to reach around behind the set.
In the HDMI Settings, it's set to 4K 30Hz, but it has Recommended next to the 1080p 60Hz. When plugged into HDMI5, it sets 4K 60Hz and says Recommended. I have HDMI 2.0 cables on this path, plenty of Internet speed and 4K package on Netflix.
Anyone experience this sort of shenanigans? If I was possible to connect my Xbone One's USB tuner to the Shield and there were Amazon and Vudu apps, I'd just run to HDMI5 and call it a day, but since it's not, it's a problem. TIA!
FWIW, when plugged into the Vizio's HDMI1 port, the receiver shows in the input list as "AV Receiver", the label I'd given to HDMI1. However, when in HDMI5 and running device discovery, that becomes "AVR-X2200W" on the list, the model # of that Denon.
