Hdr Sr12 Software Decoding OnHardware support Currently macOS supports software decoding on Macs with 6th gen Skylake processors, and hardware decoding on Macs with 7th gen Kabylake processors and above.Macs with Skylake processors are able to play 4K videos encoded with the Rec 709 color profile, but are not capable of smooth playback of videos using the HDR standard Rec 2020 color profile. Decoding on GPU is not currently fully supported on any Mac, but the graphics card does help with scaling. Windows does support HEVC decoding on GPU for Nvidia and AMD cards. However, Nvidia only outputs 8 bit video signals on GeForce cards. Any HDR videos using a wider gamut than P3 will have their color space squeezed down. Under Windows, users must enable HDR mode in the control panel in order to display the content correctly. ![]() If you enable HDR mode the Windows desktop environment will appear washed out. Currently, Windows cant automatically enable HDR mode solely when videos play. Streaming video support Neither operating system currently support streaming HDR content from popular video sources. Under macOS, HDR videos streamed from Netflix or Prime will be squeezed into the P3 color profile. This isnt an issue unless the content uses an extremely wide gamut. Under Windows with HDR mode on, HDR videos streamed from Netflix or Prime night attempt re-enable HDR mode and freeze. Currently iTunes only streams HDR content to Apple TV, so neither macOS or Windows can playback HDR content. Not sure about the iMac Pro but I might guess it works on Vega there since it doesnt have an Intel iGPU. The biggest difference for streaming services is that Windows supports 4K DRM but macOS does not. You currently cant play 4K iTunes, 4K Netflix, or 4K Amazon Prime etc. Not quite correct. Hardware GPU based decoding of 4K HDR is fully supported on Kaby Lake or later, but this is on the Intel iGPU. You did not specify discreet or not so it can be a bit confusing to some. Also, its confirmed that the RX580 (the same GPU as in the Apple eGPU developer kit) also able to perform HEVC hardware decoding in the current 10.14 beta. I have this GPU in my Mac Pro now. I have done the test by myself (as per the following screenshot). K HDR HEVC BT.2020 video can be play back smoothly in QuickTime Player on my Samsung CHG 90 with just the RX580.
