Windows 10: Cannot turn on HDR mode in Windows 10 Pro N.

I don't know if that feature is missing from the N version or something else.

When I click the button both screens go black for a sec then I see that the option is still turned off. (Tried with regedit too)

From the 3 things that say your display supports HDR in the same menu the bottom 2 say yes and the first which is video, for some reason is no.

I connected my TV through HDMI 2.1 to my PC. I can stream HDR content through DLNA and it plays fine, with HDR.

My TV is a Philips 43PUS6504/12. Not really HDR capable in brightness but I would still like to enable it Windows if possible.

Guide 3: Reduce Frame Rate.

can not turn on 10-bit video decoding for enabiling HDR mode

Hi tahmid alam fahim,

To play streaming high dynamic range (HDR) video in Windows 10 (version 1803), the built-in display for your laptop, tablet, or 2-in-1 PC needs to support HDR. To find the specifications for a specific laptop or tablet, visit the device manufacturer’s website.

Here are the requirements:

• The built-in display needs to have a resolution of 1080p or more, and a recommended max brightness of 300 nits or more.
• The Windows 10 device needs to have an integrated graphics card that supports PlayReady hardware digital rights management (for protected HDR content), and it must have the required codecs installed for 10-bit video decoding. (For example, devices that
  have a 7th Generation Intel Core processor, code-named Kaby Lake, support this.)

To check if your Windows 10 PC has the required hardware to display HDR, and to find out if your display supports HDR10, yo ucan follow the steps below:

1. Press the Windows logo key + R, type
   dxdiag, and then select OK.
2. Select Yes at the prompt.
3. In the DirectX Diagnostic Tool, on the System
   tab, look in the System Information area.
4. To save the information to a file, select Save all
   information, and then name and save the text file.
5. Open the text file, and look at the value for HDR Support. If it says
   Supported, this indicates that your display supports HDR10.

Upon researching, I have checked that your device does not support HDR mode. You can check this

link for more information.

Should you have further queries, feel free to post it.
