    NUC6i5 video decoder display mosaic

    JohnTse

      Hello,

       

      My NUC6i5 with graphics driver V15.45.2.4481 displays 64x64 pixels mosaic when all the following conditions are matched:

      1.  Use hardware video decoder (DXVA), and,

      2.  The video file is H.265 8-bit encoded format, and,

      3.  The width of the video is 1920.

       

      The issue is also found in previous driver versions.

      The issue is not found for H.264 format, nor 10-bit H.265, nor 720p, nor 4K video.

       

      Here is a example video: http://video.h265files.com/video-h265.mkv

      and the screen shoot of upper left corner:

          Hi JohnTse,

           

          Could you please attach the result of the Intel® System Support Utility and the Graphics Report?

          https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility

          Intel® Graphics Report:

          http://www.intel.com/content/www/us/en/support/graphics-drivers/000005848.html

           

          Is it straight connection HDMI to HDMI, DP to DP, etc?

          What is your Monitor’s model?

           

          Regards,

          Hellen.

            I have tried both HDMI and DP, 4K and FHD monitors and a 720P projector. All have this issue.

            My monitor is Viewsonic VX2475Smhl-4K.

             

            I have another NUC D34010, which does not have this issue.

              You are using Windows* Server 2008 R2 (6.1.7601) on your Intel® NUC6i5SY, I suggest you to use one of the supported OS on this Intel® NUC; since Windows* Server 2008 R2 is not on the OS compatible list there are not drivers for it.

                  Please try installing all windows updates, and then I recommend you to uninstalling current driver version installed, using this method;

                  • Open the Device Manager.
                  • Find the Intel Graphics Driver.
                  • Right click Intel Graphics Driver and select Uninstall.
                  • Select the check box
                  • Delete the driver software for this device.
                  • Reboot the computer after the uninstalling process has finished.
                  • Try installing the driver manually.

                      This problem is still the same with updated graphics driver version 4501.

                       

                      And I also found the same thing in many Intel 6th CPU desktop or notebook systems.

                       

                      Is this a watermark 'feature' for trial of Intel HEVC decoder? But why it works well for 4K resolution?
