I have a MI TV 4 and i tried playing 4k videos using the Youtube App provided on the TV however it doesn`t play in 4K resolution. The maximum resolution it shows is 1080p. I sideloaded Google Chrome and opened Youtube as Desktop Site , tried playing 4k but it stucks a lot .. I am having 200 mbps connection which is good enough for 4k content.. What's the reason for it ? Please advice.
