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 -

Direct3D® Version -

OpenGL® Version -

OpenCL™ Version - 22.19.685.0

AMD Mantle Version -

AMD Mantle API Version - 102400

AMD Audio Driver Version -

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
