Hi I have just purchased a PS4 pro and my TV has 4K but not HDR. When I switch my TV to HDCP 1.4 mode In resolution settings all options are available however when I switch it to 2.2 mode it will only go as far as 2160p (YUV420). 2160p - RGB is greyed out. I'm not sure which one to use as I have heard 2.2 is newer and better but without the RGB option is it worth changing it to that?
