I have a problem playing 4K content on my nVidia Shield / LG tv
The Shield and Emby app run in 4K resolution. I have 'Enable refresh rate switching' and 'Prefer exact refresh rate' both enabled in Emby.
Whenever I play 4K content, the refresh rate is changed as expected, but the resolution is changed from 2016p to 1080p. There is a 4K display mode available at the same refresh rate.
When I turn off 'Enable refresh rate switching', the content is displayed at 4K resolution, however the video becomes kind of choppy. When I turn it back on, the video is smooth as butter, but the resolution goes back to 1080p. The 'Prefer exact refresh rate' option is irrelevant here.
I've tried to change the resolution back to 4K at playtime in the display mode menu, but that seems to break HDR.
Anything I can do to have both smooth video AND 4k resolution?
