Hey there, I was following another thread about black levels in the video frame vs the bars on top/bottom (2.35 content) for 4k via this thread and thought, hey I just noticed this!
So I decided to try once more to figure out what the proper settings should be and upgraded kodi via these instructions since the above thread said the newer version should have a fix:
I was using the buster 4.9 Leia and saw the note at the end of the discussion about matrix having a fix for this. This is something I’ve struggled with for a while getting the right settings, so it’s not just a v18 vs v19 issue for me (seeing same outputs unfortunately). I’ve also bypassed the AVR and getting the same black outputs as having it in-line.
I’m running a Denon X4400H to a Epson 5050UB. I have the Denon set to enhanced HDMI for 4k sources and all processing turned off. The only feature I have turned on is where it will show the volume on the screen but no other processing of the video. (though I have turned that off as well and it hasn’t changed anything).
It doesn’t matter if I set limited range on or off in kodi, it looks the same on the projector. I have EDID set to advanced on the projector, and I’m seeing a 4k 10bit 444 HDR signal according to the info, but the blacks are not as dark as they should be. I can change the color space on the proj to limited, and everything gets darker, close to where I would expect them to be. But the bars are still one or two levels higher than the content.
Setting it to auto or full on proj leaves greyish blacks everywhere. I was hoping the new devel version would show properly in auto or full. And again, I get the same output if I change kodi to limited or not (the screen blanks out while it changes, but visually no difference).
I’m just wondering if someone could please take a look at my logs and provide any hints as it seems I should be getting deeper blacks? I used to test with some NUC’s long ago and I remember changing to limited in kodi it would change the black levels on the projector (I always used full on both ends), but my testing NUC is no longer alive.
This is with the projector set to full or auto (same result): setting kodi to full or limited doesn’t affect the output at all.
This is with the projector set to limited, much darker (everywhere) but still a shade or two above the content.
