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:

• Press the Windows logo key + R, type
  dxdiag, and then select OK.
• Select Yes at the prompt.
• In the DirectX Diagnostic Tool, on the System
  tab, look in the System Information area.
• To save the information to a file, select Save all
  information, and then name and save the text file.
• 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.

 

Windows 10 HDR bug - Pink pixelation and Banding in bright areas of the video


Pink Pixelation and banding in HDR Videos on my HDR TV (Even the preview video included in recent insiders build). Facing this on stable build also. I'm on latest Insider build, still the HDR playback isn't fixed since the Fall creators stable update. I experience all types pink pixelation on ground, sky and water which are moderately bright areas in a HDR video. TV completely supports HDR and it's a 10 bit panel. There's a lot of banding in sky. Tried various custom settings in Nvidia panel too but that doesn't help. In Netflix, pink moving pixilation goes on the face of Actors. For gods sake, demo video inbuilt for HDR in windows 10 also looks awful with banding and pink moving pixels in sky. Attached some screenshots and a video for reference. ***I played the same files on TV natively and it looks gorgeous with true HDR.

Hardware Used -
Laptop- Acer Predator Helios 300
Processor - Intel 7700HQ
