Is there a setting to enable it I missed?
Back in feb / March I ripped my own UHD discs of ‘transformers’ and ‘Thor Ragnarok’ both as full mkv rips using make mkv
Both resulted in files that where noticeably flat in colour and washed out blacks - I ended up ripping the 1080p Blu ray and comparing them
Before deleting the uhd rips as the results where so dissapointing
I have moved this to a new thread as it was off-topic where it was.
This is a bit vague. Are you watching a UHD rip?
Have you enabled HDR?
Hi,
Try echo 1 > /sys/module/am_vecm/parameters/hdr_mode to force HDR -> SDR conversion, regardless of detection.

Waited to reply until i had time to ‘re rip’ one of my UHD’s.
Should ‘Enable HDR Autoswitching’ be turned on or off
I have a 1080p non HDR projector so i assumed off?
I assumed the above command is for ssh, thats not something im comfortable doing.
If you don’t have an HDR set it should be off.

There is definitely a difference between the native Rec 709 1080p colours and the colour from the UHD file - it does look more washed out ;
Blu Ray
UHD
As explained before, there is no standard for converting Rec 2020 to Rev 709, so it is guess work.
There will be options to select tone mappings in future
