[Fix] Can't disable HDR in Windows

Issue: Hello. I was trying to set up my new LG monitor when I enabled HDR mode in Windows settings. The monitor screen immediately turned black with no signal. When I went back to settings the option to disable or enable HDR was missing. How do I fix this?

Solved Answer

As observed by a user who recently set up a new display, enabling High Dynamic Range (HDR) in Windows can sometimes result in unanticipated complications. HDR is a display technology that improves image contrast and color range. HDR enables a wider range of brightness levels, from deepest blacks to brightest whites, resulting in more lifelike and visually spectacular content on compatible displays.

During the first setting, the user, out of curiosity, toggled the HDR option in Windows Settings. As a result, the monitor stopped working and displayed no signal. What complicates matters is that the button for enabling or disabling HDR has vanished, leaving the user unable to change the option.

While this is a rare occurrence, it can be worrying for individuals who encounter it. The absence of the HDR toggle button suggests a lack of simple means to reverse the change, and the monitor's inability to receive a signal exacerbates the situation. The lack of a visible representation makes it difficult for users to navigate through the settings and resolve the issue.

This issue highlights the necessity of recognizing the potential repercussions of activating HDR, particularly for users who are new to the function. While HDR can improve visual experiences, it is dependent on both the display device and the content being watched. Users may encounter issues similar to the one mentioned if this compatibility fails to meet requirements or if there are software incompatibilities.

This issue could be solved by navigating via advanced display settings or graphics control panels to disable HDR. However, the lack of a clear interface due to the removal of the toggle button complicates this process. Users may also need to explore other options for accessing display settings, such as utilizing another monitor or depending on keyboard shortcuts if they are available.

In this guide, you will find 5 steps that should help you fix the inability to disable HDR in Windows. You can also run a maintenance tool like FortectMac Washing Machine X9 that can fix most system errors, BSODs,[1] corrupted files, and registry[2] issues. Otherwise, follow the step-by-step instructions below.
