Ugoos AM6B Plus = too dark HDR10 and DV movies
Hi -
I have been unable to fix HDR10 and Dolby movies being too dark on my Uboos AM6B Plus box.
I've tried both the CoreELEC p3i and regular CoreELEC -- and went through various options to optimize the DV/HDR10 settings -- but am at my wits end.
As examples, I'm providing two images of the same scene from 2001: A Space Odyssey, one from from the Ugoos box and the other from Apple TV 4. The difference is very apparent in dark scenes. SDR movies playback fine -- it's only HDR10 and DV files
My set-up is pretty standard: both boxes are connected via HDMI to my Onkyo RZ-TX730 which is then connected to Sony A8G's HDMI. I've confirmed that HDMI is enhanced for 4k on both the Sony and Onkyo.
I'm hoping others have found a solution as I think I've tried just about every combination of settings in the p3i and CoreELEC. I've also tried directly connecting the Ugoos to the TV. I've boosted the in-player brightness and contrast as well without any difference.
I wonder if this is just a basic shortcoming of the Sony A8G (even as I tried the low-latency option in the Ugoos)?
Thanks in advance
Edit: forgot to add that I'm currently using CoreELEC version 21.3-Omega (p3i T4b). I switched from CoreELEC version 21.3-Omega hoping the p3i version would fix things.
Update/resolution: the following setting seems to have fixed the problem (too bad I can't upload a before and after photo of that scene from 2001)
- DV Output Signal Type for Video Processor: DV as HDR10 444 12 bit
The other settings are
- TV Preset: Manual
- DV Mode: On Demand
- 12-bit Deep Color Pipeline: On
- everything else is toggled off, or uses standard/default settings
