Hi.
I've open this new thread because i don't find any other related with this problem.
I've tested last nightly build of LibreElec with Kodi 18 in Minix U9 S912 and I found some problem with HDR, 4:4:4, 10bits samples. I've tested HDR 4K 4:4:4, 10bits, 59,96Hz and it didn't play it correctly. I've added resolution in whitelist option in Kodi, but i get dark screen. (i've commented this issue in kodi forum).
However, in wrxtasy build 8.2.4.2 switching is automatic from 1080p, 4:2:0, 8bits GUI --> 4K, 4:4:4, 10bits HDR.
I’m not an expert in this field but if your required some logs or test, tell me.
Thanks.
