This article describes why HDR option may not appear after successfully updating to Windows 10 version 1709 or newer.
The option to enable HDR is not appearing under the "Display Settings" section.
- Your processor must be a 7th generation (or newer) Intel® Core™ Processor (Intel® Celeron® Processor and Intel® Pentium® Processor do not support HDR)
- Verify the revision number of the HDMI port of the motherboard.
- The HDMI port must be HDMI revision 2.0a to support HDR
- The DisplayPort must be DP 1.3 to support HDR.
- Using USB Type-C to HDMI or DP adapters will not work unless they are specifically rated to support HDR.
If the issue still occurs, check with your computer manufacturer and use the driver software provided by them. Computer manufacturers might have changed the features, incorporated customizations, or made other changes to the graphics driver software or software packaging. Intel supplies generic versions of graphics drivers for general purposes.
