Wow, you people are... First you say you don't need it, 720p and 4k looks the same. To these people, please get eye surgery, your eyes are failures.
I just got a used iPad Air for 100usd, and i want to watch 4k video. Seems to be limited to 1080p so i googled and here i am.
There has to be a way, I'm still searching. But if there are visually-impaired sheep who are saying "you don't need it" obviously neither Apple or Google are going to do anything about it. Wake up humans.
Ps it's my first time seeing a discussion where users are saying they rather not or don't want a better feature. The world of Apple....
