And difference LE and CE
LibreELEC is focused mainly on x86 and RPi.
Most of the CoreELEC team is focused on Amlogic, we also collaborate with the OSMC developers who are also focused on Amlogic because of their Vero4K device.
this is for me important part to switch over, If im satisfied im stick to CE
Don't know yet witch one is better but first impression is that CE running fast(er) on interface.
builds consist of the OSMC kernel and numerous patches which fix a number of problems related to running Kodi on Amlogic hardware along with the very latest and bleeding edge version of Kodi.
wrxtasy builds are Krypton (17.6) where as CoreELEC is Leia (18).
First quick test of 4k with and without HDR and 1080p are good just test 5 min. yet.. , will watch complete movie tonight)
When set to 4k 4096x2160 max 24fps or 3840x2160 max 60fps other movies 720p, 1080p works fine. But the output is where you put the setting on
There is a option whitelist screen resolutions (from 720 to 4k ) also, did not play with that yet or see what that is doing.
I can put my TV HDMI settings on version 2 without having a black screen. On LE need to have this on HDMI version 1. Maybe it's a TV thing but this is different for me.
My setup by the way
Panasonic viera CX800 65" 4k (with hdr)
