        You are welcome. Thank you very much for providing those updates. We are glad to hear there was an improvement on the video quality when using Windows® Media Player.
         
        Yes, if you have the option to test an HEVC x.265 file running in 1080p with both players, please try that just to confirm how it works.
         
        Any questions, please let me know.

          Well, the good news is that HEVC x.265 running at 1080p runs well on all three video players.

           

          Windows Media Player still seems to have the best resolution, but all three look and sound quite good.

           

          That just leaves HEVC x.264 (which I haven't tried) and
                                     HEVC x.265
          trying to play at a resolution higher than 1080p.

           

          Windows Media Player will play the video, with a rapid chop, but without audio.
          VLC                               will play the audio, intermittently, but with frozen video..

           

           

           

          Argh,

           

          I'm still waiting for the day I can play UHD video on this screen.

           

          :-)

           

          Thanks for all the help, and please keep me updated.

              I just received an update on this matter, Skylake and newer generation graphics controllers have HEVC and AVC hardware decoding capabilities. Could you please provide samples of the videos for us to test them?

              Did you installed a codec pack like CCCP or Klite? If so, please test the videos without the codec pack and instead rely on the codecs provided by the video playback application itself.

              Just to let you know, we have been testing HEVC HW decoding on SKL and it works correctly on Kodi 17.6 and to a lesser degree MPC-HC.

              Any questions, please let me know.

                  Apologize for the delay,

                   

                  I have not installed any codec pack.

                   

                  I'll send a video clip.  Please let me know the maximum file size that I can attach here.

                   

                  Thanks again,

                  Dugen

                   

                  PS - By the way, even UHD 4k videos from YouTube don't play perfectly.  Even when I pause the video to let it load all the way, the playback is sometimes choppy, and other times stops completely for half a second or so before resuming.

                      Here is a random video clip that I downloaded from YouTube.  It was saved as a 4k .mkv file.

                       

                      https://ufile.io/rarbt

                       

                       

                      With Windows Media Player - Only Video, No audio, and the video is choppy (a consistent maybe 3 stops per second).

                      With VLC                              - Only audio, no video.  Occasionally tries to render something, but it just comes out at large light gray squares.

                       

                      This is consistent across numerous video clips.  This being only just one of them.

                       

                       

                      Thanks so much,

                            On my pc i have difficulties playing uhd videos too.

                             

                            Dell precisiontower 3620, intel hd graphics 630 (C236 chipset with 7700k):

                            Movies & TV, media player, vlc player: cannot play video

                            Custom pc with asus prime B250M-K, intel hd graphics 630 (B250 chipset with 7700):

                            Movies & TV, media player, vlc player: video plays ok

                             

                            Now I tried media player classic (https://mpc-hc.org/) and surprisingly the video plays ok,

                            with a cpu load of 3% and a gpu load of 55%.

                             

                            Perhaps you could try this player too, and if it works, what is different to the Movies & TV application?
