I realize this is probably a nob question and I am missing something here, but I haven't been able to find any answer to this problem, even though I was digging really hard. Whenever a streaming app allows you to see screen resolution in the settings, in my case it always shows 1080p even though all of my TVs are 4k. Same goes for Kodi, Cpuz also shows 1080p only. It is my 3rd Chinese Rockchp Box (this time HK1 RK 3528), and it has allways been the same, the prevoius ones even stuttered when playing 4k. Am I doing something wrong, or is it just jet another Chinese scam?
