I just bought a 4K tv, using a high speed 2.0 hdmi cable connected to our MyGica ATV 495, with display settings on 4k 60hz but I can't seem to find a way to get the youtube app to show 4k in the quality settings, it always only goes up to 1080p. My tv shows that the screen is currently 4k resolution, just can't seem to get any 4k content playing from youtube. your help is appreciated.
Sadly, it doesn't run the Android TV branch of Android, so it will not be discussed here. Go to /r/androidtvboxes
