I have a Wetek Play 2 (S905) which until now has been connected to a Sony Bravia Full HD (1080p) Smart TV (2015 model) and I've run various "flavours" of LibreELEC (and CoreELEC), both Krypton and Leia Alpha with no problems - it really is a good, responsive box.
I've now upgraded to a Sony KD-55XE596 4K Smart TV, which is capable of displaying full 4K HDR 60fps/HDR10 signals and will auto-switch to HDR10 if it detects this (works great on Netflix). The Wetek Play 2 is connected with a 4k compliant HDMI 2.0 cable.
Of course, I am now wishing to watch 4K HDR10 media/movies via LibreELEC.
If I watch HEVC/x265 4K HDR contentt with LibreELEC on Wetek Play 2, then the media plays OK (smooth with no stutter) but the TV does not auto-switch to HDR10 and colours are "washed out". If I manually select HDR on TV, then the image is glorious. If I watch the same content via the TV's built-in Android Kodi/SPMC via a USB HDD (all my media is on 2 5Tb powered USB HDD - the Play 2 has no issues with this), then the media plays perfectly and the TV auto-switches to HDR10 mode.
The box will not play full 4K HDR 60fps media (like these demos -Sony: Mont Blanc HDR & Sony Bravia OLED HDR10) the image stutters and the TV reports the fps is only around 13-15fps and there is no HDR auto-switching. Again, playing this same media directly via the TV's built-in Android Kodi/SPMC via a USB HDD, then the media plays perfectly and the TV auto-switches to HDR10 mode.
I was under the impression that S905 boxes with LibreELEC can play/output HDR content via conversion, so why is the TV not detecting the HDR signal?
As the box cannot play full 4K HDR 60fps media without stuttering, then would it be worth me investing in a S912 box (Minix neo u9-h, MECOOL M8S PRO, Beelink GT1 Ultimate, H96 Pro +) and if I did, what LibreELEC would you recommend; official or kszaq ??
Many thanks and apologies for the long post!
