I have a 50PUS7303/12 4K android tv about a year now. Some videos on YouTube doesn’t play in 4K or 1080p and shows maximum resolution of 720p. I think it does it only in videos that are 60fps and above because the rest of them play normally in highest quality. On Netflix doesn’t show anything above 720p. Both apps and tv are updated. I have done factory settings multiple times but nothing is changing. Please help!
