generiq 113 Posted December 31, 2022 Share Posted December 31, 2022 You really didn't understand. It isn't being 'processed'. The colorspace is being respected. Your projector is just showing the generic flag that Windows is attaching. sRGB will remain sRGB etc. Color management is being done at the window and not at the display/projector. The old way of doing this was to take control of the display and physically switch between colorspaces. Windows has a better way of doing this, now. DVDfab might be using Vulkan to do it the old way or possibly you have a GPU driver that's old enough to be exploited for this purpose. Either way, just turn HDR on and leave it on. I wish everyone would understand that HDR and color are separate entities. One is light and the other is color. Link to comment Share on other sites More sharing options...

Mopar_Mudder 14 Posted January 2, 2023 Author Share Posted January 2, 2023 I haven't had time to mess with it anymore.

Videos are too light and brightness fluctuates unless you turn off hdr-compute-peak. For me this is sign that some form video processing is happening in background. Also you need to activate windows HDR on/off (windows+alt+b shortcut works). My solution has been to use Kodi Matrix + EmbyCon for 4k HDR content and Emby Theater for all SDR content. MPC and madvr combination also works, but you need to edit external player settings in order to activate correct player and you lose resume ability for HDR.

Mopar_Mudder 14 Posted January 7, 2023 Author Share Posted January 7, 2023 Did some testing tonight. Turning on HDR in windows definitely make the picture get washed out. Blacks look more dark grey. Link to comment Share on other sites More sharing options...

I have also tried suggestions found from mpv GitHub thread (vo=gpu_next HDR passthrough settings · Issue #10158 · mpv-player/mpv · GitHub) without success in ET or standalone mpv. In the latter info screen suggest that gpu is used to color decoding, peak detection, colourspace conversion, tone mapping and color encoding.

jokunen 1 Posted January 13, 2023 Share Posted January 13, 2023 It appears that reason in my case was debanding parameters in mpv.conf. After deactivation, HDR video looks correct. 1 Link to comment Share on other sites More sharing options...

Are you making changes in the Nvidia consol? Are you altering anything from default in Windows? etc.... Link to comment Share on other sites More sharing options...
Mopar_Mudder 14 Posted January 23, 2023 Author Share Posted January 23, 2023 Just turning it on. There is a slider bar in windows to adjust brightness but I didn't mess with it, maybe I need to? Link to comment Share on other sites More sharing options...

Movies are ripped with DVD Fab So, when you play any HDR video, do you always get the same result? If you have an HDR movie that wasn't ripped with DVDfab, and is in an mkv container, same result?

generiq 113 Posted February 5, 2023 Share Posted February 5, 2023 (edited) @Luke here's an idea for you. For 'old skool' people who still want to have the display switch in and out of HDR, you could provide an 'advanced' option to use --gpu-api=vulkan Quote This does not seem to affect other graphics APIs, such as Vulkan, though. MS seems to have much less say on what the driver vendors can or cannot do on that side. So if you do the same, but with --gpu-api=vulkan - at least on nvidia you will get the display configuration switching to HDR with HDR content.
