  1. Awesome guide I always come back to. New problem just cropped up, i just uninstalled everything and reinstalled fresh and while mpc-hc and mediaplayer work fine, I’m getting audio only in Potplayer and a black screen for video. When I select automatic video rendered instead of madashi i get video but that kinda defeats the purpose right? 960 GTX using DXVA2

  2. Hello Ranpha
    Didn’t update to the lastest compile (31th August) yet, but i will

    Just to add up something
    If i use “Tonemapping” for the HDR setting , but without the “Output video in HDR” checked so that my display stays in SDR (like this i mean https://ibb.co/6RcW5Lc) – i get a very very dark image, meaning in SDR , it’s not how it should be

    When it’s checked, it looks pretty cool, but is this really better then “Passthrough HDR to display” option?

    Did i miss anything or?
    Thanks a lot, much appreciated

      • Ok, i will test like that in multiple scenarios :)

        I don’t know
        I didn’t measure it, just took the value from a calibration setup from a forum, someone that measured the nits in SDR / HDR
        That’s the max SDR value achieved

          • HDR mode sets it automatically to 100%

            Ranpha, is it possible to create a guide for => madVR Tool: MadmeasureHDR Optimizer
            Read about it briefly, seems really cool and raises the bar in terms of HDR displaying

            Thoughts on that?

  3. Hey Ranpha

    A lenghty post, please bear with me, as this might surely interest other readers of your blog as well
    It’s HDR enablement related
    As you surely know , HDR is about brightness / contract / making the picture come alive
    Any TV that supports HDR enters a HDR-mode, when such enabled content is available.
    The picture-presets on the TV Set are also HDR related or SDR related (i mean the picture presets / custom presets that one decides to calibrate on)

    My questions are
    -For example in Windows, you’ve mentioned we shouldn’t really enable HDR in Windows (Windows HD Color, i think it’s called) in order to be able to watch HDR in PotPlayer
    But if we don’t enable it, then the TV doesn’t switch to HDR mode when you play a movie
    What should be done when playing an HDR movie in PotPlayer? Just switch the TV on HDR-picture preset and play the movie as you would an SDR movie in Potplayer?

    -I’ve tried enabling HDR in Windows and playing an HDR enabled MKV movie. First enabled the Windows HD Color mode.
    Well, Potplayer or MadVR switched my TV resolution back to 4K SDR
    What causes this, please?
    or better said
    What are you suggestions on this, can you please shed some light, i find it really important to have a perfect working HDR enviroment in PotPlayer / MadVR

    Many many thanks

    • Assuming you have the GPU hardware (GTX1070 or higher), just use the tonemapping option. If you choose to use that option, the 4K TV will stay at SDR mode. And so is Windows. No need to manually turn on HDR color in Windows at all.
      Only when you use the passthrough option, then the TV will go to HDR mode, usually without need ing to turn on HDR color in Windows.

      • Hey Ranpha
        Thanks a lot, yes, 1080 Ti here, GPU
        Ok, so Tonemapping (being better than passthrough) => leaving it SELECTED & configuring it PLUS switching to the HDR picture preset on the TV set manually myself, am i right? Would that be the same?
        Appreciated

        PS :
        Thanks a lot, i would really need to google & read more about each config in madVR explained

        • Later edit after tryout of passthrough method just to check if it works : it does the same. when playback starts, TV goes to “HDR” mode, but when going full-screen it switches back to SDR settings / preset

          What could be wrong, please? Attaching you a set of screenshots here, let me know what else might be wrong…

          Nvidia driver installed is => 431.60

          Many thanks, hope i can sort this out somehow :)

          • So, in windowed mode the TV goes to HDR mode but the TV went to SDR mode in fullscreen mode? If that’s te case it is either Windows’s bug or nVidia drivers bugs. Try older drivers?

            • Ranpha
              Two mentions, good news included :)

              I’ve updated driver of the GPU to latest (436.02) version
              Right now, i can use the passthrough method error free, yet the tone map using pixel shaders does the same error
              When fullscreen it just switches the TV back to SDR

              My 2nd topic, please, i’ve never quite figured it, but I should ask
              I’ve noticed that 90% of movies / tv shows have 23.976 (24 frames per second) , yet PotPlayer always displays that number there, much bigger than 24p, like a conversion to match the Refresh Rate perhaps?
              What kind of option is enabled so this happens now ?
              Is there any way to play these at exactly 24p ? Is there any benefit from it or?
              Any suggestions / comments welcome

                • Ok, so Tonemapping without checking the “Output video in HDR format” => leaving it SELECTED & configuring it PLUS switching to the HDR picture preset on the TV set manually myself, am i right? Would that be the same?

                  My display is set to 60Hz in 4K resolution

                  • I need your advice on the tonemapping, still.
                    Question is
                    -SDR TV Preset + Tonemapping or
                    -HDR TV Preset (custom made, i’ll have to manually select it) + Tonemapping ?

                    Thanks

                    • Hey Ranpha
                      Thanks a lot
                      Well, right now => after the driver update, i don’t get any of the previous errors
                      Tonemapping works even with “Output video in HDR format” checked, without erros

                      Thanks for your help & advice
