I have a Vero 4K (media connected via a USB disk), a Samsung UE65KS8000 (EU model name, in the US it’s called UN65KS9000) TV and a Denon AVR-X3300W AVR. Connection: Vero > AVR > TV
Before the October update I could play back everything almost just fine. The one issue I had was the well known banding issue. I enabled the auto HDR switch in the menu but that didn’t worked for me Vero just crashed when I tried to play a 4k file. So I turned it off and installed this “[deprecated]” hotfix. Sadly the hotfix did nothing for me, banding still remained, but at least I was able to play back everything but ofc only in 8 bit with banding.
AFTER I installed the October update the AVR OSD finally says 10 bit but and the playback starts but stops after a few sec later and I get no audio and no video then i comes back for a few sec later and goes black and mute after a few sec again. So now it makes all my 4k files completely unwatchable… (1080p and SD works fine)
Can someone help me?
From the TV’s manual:
When you connect the TV to the external device that supports only UHD 24 or 30 Hz frequency or any FHD frequency, the HDMI UHD Color function may not be available. In this case, set HDMI UHD Color to Off.
The HDMI connector with HDMI UHD Color set to Off supports up to UHD 50P/60P 4:2:0 input signals, while the HDMI connector with HDMI UHD Color set to On supports up to UHD 50P/60P 4:4:4 and 4:2:2 input signals.
Ok, hopefully I did it right. Here’s the log> http://paste.osmc.tv/asahekemor
I enabled debug logging and then i tried to play two 4K HDR file that played “well” before October uptade. With “well” I mean the output was only 8bit hence with banding but at least they played back, now most of the time I see black screen and no audio and then for a few sec I get picture + audio, then black again, furthermore I noticed several tiny white dots on the screen during I got image and audio.
