I am long time user of Odroid C2 and Samsung Q90R.
I’m using the TV in PC mode to disable all the processing as I’m very sensitive to the soap opera effect. Everything works great.
Today I purchased Odroid N2+ and installed coreelec.
Same setup of the TV (PC mode), tried many many settings on kodi, was playing with the TV settings and had to completely reset the TV settings, but the result is the same. N2+(coreelec) produces noticeably darker picture compared to C2(libreelec).
Both devices are setup 4k@60HZ.
The difference is that when I check the source on the tv, C2 says UHD, but N2+ says UHD and HDR.
Tried N2 with the stable build, and with the nightly (matrix) it’s always the same, noticeably and annoyingly darker.
Reinstalled C2 from scratch, and N2+ from scratch couple of times, always the same result, N2+ noticeably darker picture. Tried a lot of different video files, low res, hiugh res, 1080p, 4k etc.etc.
So the only obvious difference I see is that when I play from N2+ the tv always says UHD HDR.
Is there some way to disable HDR on N2+ or coreelec or kodi…or it’s something completely different that I’m missing.
If I switch the tv mode to BD player or Media center etc, the brightness returns to great, but then all the internal picture processing activates and for me it looks disgusting.
