    HDR WCG won't enable on Windows 10

    MSI 43GSVR 7Re laptop with 6gb Nvidia 1060

    Samsung 32hg70 monitor

    HDMI 2.0 connected to laptop using only Samsung monitor as display

    HDR WCG is an available option to turn on (SDR slider is greyed out for some reason) - once turned on, Windows 10 asks 'Do you want to keep these settings?" Choose Yes,
    but HDR WCG remains off.

    Both the 1060 and monitor are HDR capable. Both laptop and monitor are HDMI 2.0

    Any thoughts on why HDR won't turn on?

  4. HDR and WCG in Windows 10

    HDR and WCG are disabled but my Computer+TV are HDR/WCG capable

    The option HDR/WCG is not available under Windows 10 RS4 and disabled under Win10 RS5 build 17713.

    In here my equipment:

    Display TV:
    Samsung TV UHD HDR UE55MU7005TXXC (w/latest firmware: 1221.0). UHD Color function is active for HDMI.
    HDMI Cable:
    UGreen 4K HDR 60Hz Cable HDMI 2.0 Certified 18Gbps. No issues with this Cable under a PS4 Pro - HDR games.

    Computer:

    Zotac ci547-nano (Intel i5-7200u, Intel HD 620) --> I have been talking with their tech support to have a new BIOS and LSPCON Firmware update to be aligned with Intel HDR Whitepaper requirements. They already tested successfully the system (HDR compatibility)
    with two different Displays (none of them are TVs).

    Windows Version:

    Windows 10 x64 RS5 (latest build 17713)

    Also tested on Windows 10 x64 RS4 (final build)

    Intel Graphic Drivers:

    24.20.100.6194 (latest release). Same issue also under previous versions.

    In here an extract of my DxDiag report:

    Current Mode: 3840 x 2160 (32 bit) (60Hz)

    HDR Support: Not Supported

    Display Color Space: DXGI_COLOR_SPACE_RGB_FULL_G22_NONE_P709

    Color Primaries: Red(0.659180,0.339844), Green(0.244141,0.669922), Blue(0.129883,0.040039), White Point(0.312500,0.329102)

    Display Luminance: Min Luminance = 0.010000, Max Luminance = 1499.000000, MaxFullFrameLuminance = 799.000000

    Monitor Name: Generic PnP Monitor

    Monitor Model: SAMSUNG

    Monitor Id: SAM0DEF

    Native Mode: 3840 x 2160(p) (60.000Hz)

    Output Type: Displayport External

    Monitor Capabilities: HDR Supported (BT2020RGB BT2020YCC Eotf2084Supported )

    Display Pixel Format: DISPLAYCONFIG_PIXELFORMAT_32BPP

    Advanced Color: Not Supported

    I also tested different resolutions and frequencies. Same results.

    I have some doubts regarding that info reported. I have been checking where that data is coming from, and is supposed coming from here:

    IDXGIOutput6::GetDesc1

    DXGI_OUTPUT_DESC1

    DXGI_COLOR_SPACE_TYPE

    The point is, according to this guide:

    High Dynamic Range and Wide Color Gamut

    And also to this code example:

    Microsoft/DirectX-Graphics-Samples

    What determines if a Monitor/TV is HDR capable is if 'ColorSpace' is reported as 'DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020'

    My question is, where is that information coming from?

    As far as I could undertand that data is not an EDID information coming from TV. EDID information according DXGI_OUTPUT_DESC1 structure are only 'Color Primaries' and 'Display Luminance'... BUT and this is a big BUT, according to 'Monitor Capabilities' it
    is supporting G2084 and BT2020...

    Why 'ColorSpace' is not reported as 'DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020' on my system but as 'DXGI_COLOR_SPACE_RGB_FULL_G22_NONE_P709'??

    I think the issue is more or less located on how this ColorSpace is reported/calculated but I couldn´t find any more information on MS Docs about it.

    Thanks for your support in advance!
