Hello.
4k is working. There is my benchmark and proof of concept utility. You should test "Alpha" LibreELEC (on 4.4 kernel) or use Android.
Problems:

Problems:
- 4.4 kernel + MPP library - HDR 4k@60 with high bitrate does not work due to memory bandwidth problems (must be faster memory) (but standard 4k@60 should work) and MPP API problems (unresolvable problematic code that slowing/boosting decoder clocks). Developers (rockchip,kodi,libelec) stops developing on old kernel and waiting for new kernel (roll to Rockchip section)...
- 5.* kernel + video accel - Everybody waits for implementation VPU/GPU acceleration in new kernel :-)
I left this community in Aug 2019 due to PINE64 refusal to produce/deliver ROCK64-1G version 3 after more than one year of changing statuses to "planning", "evaluating", "releasing", "availability", "estimated availability" and finally "no schedule" 
. ROCK64 is dead platform without any advantage. Buy Raspberry PI 4 !
