LG 49UB850T can't play 4k videos DL from youtube

[Brian Tracy San Andres 0]

Isn't it just me, that I can play downloaded 4k videos from youtube to test the 4k capability of our TV?

I found it weird because I can play 1080p with MKV files smoothly but when I play 4k video files it say unrecognized format.

are you asking two problems? on the telly's browser, youtube can only to go 720 (not sure why).  the youtube app is much better and higher resolution (though i do not know what). 

as for .MKVs i know that 1080 almost always works, but a 4k .mkv for whatever the reason, does not. i am wondering if it would play well off of a computer to the telly
