It seems my Apple TV 4k is insisting that I use the 4k Dolby Vision video setting, at least to get started. I say this because yesterday I set it to 1080p SDR because I was watching content that is encoded in that format. Today, when I turned it on, it gave me the screen that asks if you want to try Dolby Vision. The only problem is that none of the remote buttons would work. I tried both the original Apple remote as well as my Harmony remote and nothing would work. I had to unplug the unit in order to get back to the Home screen. I guess I'll have to leave the setting at 4k Dolby Vision in order that it will work the next time I want to watch anything on it? Anyone else run into this issue? I have a Vizio "P" series display along with a Denon X6400H and the Apple TV 4k is connected to AVR via HDMI.
