Zenfone 6 is not able to show 4K content due to device specification, however, it supports HDR on youtube ...
Hmmm funny because zenfone 6 able to play 8k content but not able to run 4k content on youtube 😐

4K is defined by a higher number of pixels on your screen. Zenfone 6 is a 1080 x 2340 which is less than what 4K requires (2 times more).
Of course, zf6 can display 4K content, by they are compressed to fit on the resolution of the phone. So you end up with 1080p in reality ...
I understand now..so no matter 4k or 8k its useless to play in 1080p resolution?
Yeah but somewhat it will be sharp. but that is not noticable to our eyes
