I think your AVR doesnt have the ability to passthrough HDR UHD files, but only SDR files.
Try to connect your beelink directly to your TV and not through your AVR and check the results.
If everything is fine, then you'll know your AVR is your issue.
connected to yamaha HTR-2067
You need another AVR to watch 4k
The yamahe HTR-2067 has no HDMI 2
Regarding hdmi 2, I think my avr has it:
*This model doesn't support HDCP2.2. HDCP2.2 compatible equipments are needed to see 4K contents which are encypted with HDCP2.2.
I believe it´s why TV doesn´t support HDR
Did You try to play HDR or SDR videos ?
I have the same issue on my Sony 65“ 4K with 4K Receiver … take a look, if you Play 4K HDR, if your TV says its really playing HDR. Cause thats happened with all my 912 boxes. I got 2160p but no HDR and than the picture looks crappy. On my 905 boxes my TV says HDR and the crap in Dark areas are gone... but on 905 boxes its the only 100mbit Lan thats make 4K with high bitrate unlookable. I got a lot of buffering...
I think that the video I tried to play is SDR
(I'm sorry... it is in italian)
Spazio colore: YUV
Croma subsampling : 4:2:0
Profondità bit : 8 bit
Bit/(pixel*frame) : 0.052I don't find the way to check it on my TV (Philips 55put6101). My tv doesn´t support HDR.
That your TV dont support HDR, could be the solution. Cause, like Kzaq writes in the first post, 4k and HDR is experimentel in the Kodi builds.
