444 won't work for HDR. Other than that, it's fine.
For PC, 444, For games, you can try 10-bit 422 w or w/o HDR.
Oh shit lol, didn't realize that about the HDR thing. Cheers!
Edit - I can screen cast just fine, but the photo sharing plus app just doesn't work for me. When I try to connect to the tv wifi it fails, so the IP that you're supposed to visit won't work either. The Bravia signal goes from full to zero as it tries to connect, then back to full again.
Maybe I'll test it later with other phones.
I haven't had to time to play xv either to test my HDR settings.
