Another question, on another PC Dell Optiplex 5070 micro, there are only two displayport but no HDMI port integrated. So I bought an additional HDMI 2.0b port on the official DELL website. This additional HDMI port works well at 4K60hz. But here's the problem:
- With Windows 10/11, Kodi activates HDR very well with very nice colors and brightness!!! Perfect.
- With LibreElec 12 final, HDR doesn't activate. Yet in the settings it detects that my TV supports HDR and HLG. I can activate Hable tonal mapping but true HDR is still the best in my opinion.
I use a Sony Bravia 55AG8 4k/60hz/HDR/DolbyVision TV and an LG 27GP750-b 1080/240hz/HDR10 certified monitor which is also HDR compatible. Both have the same problem.
I also tested with my Gamer PC: intel i5-12400, UHD 730 Graphics, 32GB Ram, Asus B660M Pro CSM motherboard with its integrated HDMI 2.1 port. And HDR works very well with the Sony TV and LG monitor!
So:
I don't think the additional HDMI card is faulty because HDR works well with kodi in Windows 10/11. Do you think there's some parameter or setting that needs to be changed in LE to enable HDR with the additional HDMI card ?
Thanks in advance
