      Hi All

       

      I have recently reinstalled Windows 10 and the latest AMD graphics drivers, which are detailed below:

       

      Radeon Settings Version - 2017.1005.1719.29341

      Driver Packaging Version - 17.30.2822-171005a-318724E-CrimsonReLive

      Provider - Advanced Micro Devices, Inc.

      2D Driver Version - 8.1.1.1614

      Direct3D® Version - 9.14.10.01304

      OpenGL® Version - 6.14.10.13492

      OpenCL™ Version - 22.19.685.0

      AMD Mantle Version - 9.1.10.0220

      AMD Mantle API Version - 102400

      AMD Audio Driver Version - 10.0.1.1

      Vulkan™ Driver Version - 1.6.0

      Vulkan™ API Version - 1.0.51

       

      However, I am having issues with the Colour Depth and Pixel Format in the Radeon Settings application on my display (Hisense M3000 TV | Hisense UK) when displaying content at 4K@60Hz. Whenever I select '3840 by 2160, True Colour (32 bit), 60 Hertz' in the Display Mode in Windows Display Adapter Settings, I am only provided with a Colour Depth of 8 bpc and a Pixel Format of YCbCr 4:2:0. I have read through a number of other discussions highlighting issues similar to this on other Polaris graphics cards, however from what I understand (and I may be wrong) I should be able to output a Colour Depth of 8 bpc and Pixel Format of YCbCr of 4:4:4, as per the HDMI specification: HDMI :: Manufacturer :: HDMI 2.0 :: FAQ for HDMI 2.0. Any help with this issue would be much appreciated and please do not hesitate to let me know if you need any further information.

       

      Many Thanks
