nicko84 37 Posted May 31, 2023 Share Posted May 31, 2023 Hello, Do you now why refresh rate (60;23) with gpu-net and Auto is very bad with a lot of juddering (23,976 hz 4K video and Windows 10 with HDR) ? Link to comment Share on other sites More sharing options...
Luke 37148 Posted June 4, 2023 Share Posted June 4, 2023 HI, do you use an mpv.conf file? Link to comment Share on other sites More sharing options...

nicko84 37 Posted June 10, 2023 Author Share Posted June 10, 2023 Hello After several tests this issue seems to happen ONLY with AAC sound track (5.1 or 7.1 or else) and never with other sound track format like EAC3, TRUE-HD, AC3 ... ET video settings : Audio : All formats selected Stats for nerds with Video and AAC sound track : i've a lot of drop frames so a lot of judders Stats for nerds with Video and TRUE-HD (ATMOS) sound track : i've no drop frames so no judders 1 Link to comment Share on other sites More sharing options...
generiq 113 Posted June 11, 2023 Share Posted June 11, 2023 You're using nvdec for hardware decoding, don't use that. Use d3d11 or leave it on auto. Link to comment Share on other sites More sharing options...
nicko84 37 Posted June 11, 2023 Author Share Posted June 11, 2023 (edited) I'm using auto... The thirst and second screenshots in my post are the same (mistake). This is the fist and right one : I've also tried with d3d and d3d copy back and all others hardware acceleration settings et no way...always judders.

generiq 113 Posted June 12, 2023 Share Posted June 12, 2023 Do you see it? It's still using nvdec. I've never seen mpv fall back to nvdec. So you're doing something to affect this. Link to comment Share on other sites More sharing options...
generiq 113 Posted June 12, 2023 Share Posted June 12, 2023 Try testing with an mpv.conf. In the settings set hardware acceleration to unset. And add hwdec=auto in the mpv.conf Link to comment Share on other sites More sharing options...
generiq 113 Posted June 13, 2023 Share Posted June 13, 2023 (edited) Does your motherboard have an on-board gpu, an Intel or Radeon maybe? If yes, have you disabled it? Edited June 13, 2023 by generiq Link to comment Share on other sites More sharing options...
nicko84 37 Posted June 13, 2023 Author Share Posted June 13, 2023 I will remove the mpv.conf, maybe confusing for ET and try again (?) I've disabled on-board Intel GPU for a long time and using Nvidia 1050ti Link to comment Share on other sites More sharing options...
nicko84 37 Posted June 13, 2023 Author Share Posted June 13, 2023 Yes it was an mpv.conf file ! But i thought the mpv.conf was not read with graphic acceleration on Auto (?)...and i was wrong obviously... Sorry for this misunderstanding ! Link to comment Share on other sites More sharing options...

When Windows boots, it loads the drivers required for the hardware it detects during boot. You need the d3d11 windows driver. If you disable the on-board gpu, Windows will probably not load that driver. YOU NEED THAT DRIVER, for optimized hardware usage. You also need it for HDR pass-through and several other functions. If you can only use nvdec, HDR will always be tonemapped and require more processing, which is probably why your gpu is struggling and dropping frames. FOR EVERYONE! DO NOT DISABLE YOUR INTEGRATED GPU! 1 Link to comment Share on other sites More sharing options...
nicko84 37 Posted June 18, 2023 Author Share Posted June 18, 2023 Hello, Thanks generiq ! Without mpv.conf and IGP activated all is allright now with Nvidia 1050ti, no more dropping frames and judders, d3d11 is ok with or without refresh rate activated. 1 1 Link to comment Share on other sites More sharing options...
generiq 113 Posted June 20, 2023 Share Posted June 20, 2023 Something else to consider, if you're using Windows 11, under the display settings, you can specify which gpu each app uses. Link to comment Share on other sites More sharing options...
nicko84 37 Posted July 1, 2023 Author Share Posted July 1, 2023 Hello, On Windows 10 and HDR all is allright know with GPU Next and d3d11 but i have some pumping brightness effects with HR10 or DV. Picture on the same scene become suddenly brighter, and goes back to "normal" on the next scene... I've not these effects with ET on Shield Link to comment Share on other sites More sharing options...

Thanks If you aren't aware, your HDR is being tone-mapped. If your display supports HDR, you should enable HDR in Windows. Then then the metadata will pass to the display for HDR10.

SteveFintel 26 Posted July 10, 2023 Share Posted July 10, 2023 When I enable HDR in Windows 11, the display always is in HDR mode whether the content is HDR or not. Kodi forces the display to SDR when showing SDR content. Playing HDR content in the Windows 11 client looks dull. When I play the same content from a Fire Stick 4K, the display switches to HDR when playing HDR content. Is this expected behavior? Link to comment Share on other sites More sharing options...

That's more complicated than I want to explain, but don't compare different players. They all function differently and there is no general 'expected behavior'. Referring specifically to the player that Theater uses. It defaults to d3d11. This is Microsoft, and the behavior you see is how Microsoft has designed it. Color management is performed at the window and not by the display. There are different APIs that can change this behavior. vulkan would be the main alternative. If the vulkan api is used, then the display should be switched between SDR and HDR, and not color managed at the window. Link to comment Share on other sites More sharing options...
