No HDR in Windows 10 Color settings

[PD102]

My Windows HD Color Settings show my Display abilities for HDR Stream, Play games and WCG apps all reading no. My monitor is a HP23xw. My graphics card is a nVidia 960. What must I do to get HD quality?

External displays

To play streaming high dynamic range (HDR) video in Windows 10, your external display and Windows 10 PC needs to support HDR. To find the specifications for a specific PC or external display, visit the device manufacturer’s website. Here are the requirements:

• The HDR display or TV must support HDR10, and DisplayPort 1.4 or HDMI 2.0 or higher. We recommend displays that are DisplayHDR certified.
• The Windows 10 PC needs to have a graphics card that supports PlayReady 3.0 hardware digital rights management (for protected HDR content). This could be any of the following graphics cards: NVIDIA GeForce 1000 series or higher, AMD Radeon RX 400 series or higher, or Intel UHD Graphics 600 series or higher. We recommend a graphics card that supports hardware-accelerated 10-bit video decoding for HDR video codecs.
• The Windows 10 PC must have the required codecs installed for 10-bit video decoding (for example, HEVC or VP9 codecs).
• We recommend that you have the latest WDDM 2.4 drivers installed on your Windows 10 PC. To get the latest drivers, go to Windows Update in Settings, or check your PC manufacturer's website.
