The bug prevents users from enabling streaming HDR video after upgrading to Windows 10 1903 or later if they previously disabled the setting.
In a new support bulletin for educational versions of Windows, Microsoft says that users who disabled the “Stream HDR video” option on Windows 10 1809 and then upgraded to Windows 10 1903 or later may not be able to re-enable it.
This problem may occur if you recently upgraded to the latest version of Windows 10. When you try to enable HDR stream settings, the HRD option is not enabled.
In this article, we will cover quick steps to help you solve the “Windows 10 HDR not turning on” problem.
What is the cause of the “Can’t enable HDR video streaming” problem after the Windows 10 update
If you are connecting multiple HDR-compatible displays to your computer, make sure that the multiple monitor setup is not the cause of the problem. If you’re using a monitor plus a TV, enable HDR streaming when only the TV is connected to the computer.
In other cases, an incompatible HDMI cable can also cause problems with HDR on Windows 10. An HDMI 2.0b cable is required to stream the HDR signal. If you are using an HDMI 1.4v cable, replace it with an HDMI 2.0b cable.
If the HDR streaming option is not available for your display, it’s probably because your monitor or TV does not support HDR technology. The “Windows 10 HDR can’t turn on” problem is usually due to an improper upgrade or an incompatible HDMI connection.
