When I enabled Dolby Vision in the shield display settings the default then changes to:
"3840x2160 59.940Hz YUV 422 12-bit Rec.2020 Dolby Vision and HDR10 Ready"
So I tried picking a custom resolution that is rec.709, specifically I tried:
"3840x2160 59.940Hz YUV 422 12-bit Rec.709 Dolby Vision and HDR10 Ready"
With that selected the CX does see rec.709. With the "Match Content Color Space" setting enabled, I then tried hdr content on netflix and disney+ and it did auto switch to BT.2020. So the match content setting seems to work when your default is set to rec.709 via custom display mode and you play BT.2020 content. So I'd say the CX is working correctly and you should be able to get the shield to work by using the custom display setting.
Maybe you can help me figure out my HDMI issue with the shield and the CX since you are on a roll?
My issue is, if I set power control to IR (LG TV), whenever I switch inputs from the shield to something else (ps4, cable) the shield sleeps, but the TV shuts off. If I uncheck the IR control, the issue doesnt happen, and the shield sleeps, and I am able to switch inputs...but, then i cant use the shield remote to shut the tv off when I am done. It only sleeps the shield, but doesnt power the TV off.
Can you tell me if you see the same issue? And what your power settings are set to? I attached my power settings below
In a perfect world id like to be able to switch input from the shield to something else, and the shield sleeps when i do that, but the tv doesnt shut off. Id also like to be able to hit the power button on the shield remote, and both the tv and shield shut off. This worked fine on my qled, not sure if its an hdmi glitch on the cx?
Thank you again, hopefully you can help me here as well.
