m15, lost HDR, please help
Hey everyone. I have a Alienware m15 laptop that is only 2 weeks old. I opted for the UHD display with eye tracking technology that is full HDR. When I first got the laptop. HDR was working fine. When I went to display settings, I had the ability to toggle HDR on and off without an issue.
I have a Samsung TV that I use as a second monitor as well as an Oculus Rift. Those are the only things that I have ever had connected via HDMI or DisplayPort.
About a week ago, I booted windows and noticed that I no longer have HDR support. In the display settings menu, the option is completely gone. Plus, now all of a sudden when I do a dxdiag it is telling me my display isn't HDR capable.
I have updated both my Intel integrated display adapter as well as my NVIDIA video adapter. I think my PC may have done an update between initial use and now, but that's the only thing I have done to the machine. I am extremely ticked about this situation, since I spent several hundred dollars for the very purpose of being able to play HDR video and games. I cannot find a driver for my display at all, my device manager is just using General PnP Monitor, which may be the issue, I don't know. I called alienware support and they said this is entirely a Microsoft Windows issue and they couldn't help me. Is there maybe a display adapter for my actual screen? I find it difficult to believe a Generic Monitor PnP driver will work with the eye tracking tech.
Has anyone had this issue? Basically I just need windows to detect my laptop screens capabilities correctly!
I'm having this issue as well. It just cropped up on my M15 shortly after purchasing and connecting a new HDR external monitor. Somehow this or a Windows Update must have broken something in the drivers. I tried the earlier available System Restore Points but that did not fix it.
Like you, my Device Manager now shows the internal monitor as Generic PnP, and it also shows Device Not Migrated error in the Driver Properties. I cannot find a color profile for the internal OLED 4k display. When I bring up Windows HDR settings, it shows Yes for Stream HDR Video but No for Use HDR and Use WCG Apps. It used to show Yes for all three.
Did you find a solution to this issue?
Hi @Henisey2342 welcome to this user to user forum.
Bad Window Updates are known to mess with computer settings. If System Restore has been enabled on your OS (C:) drive, go back in time to the restore point that everything was working. If System Restore is not enabled, go to This PC, right click on OS (C:) drive, to open Properties, Tools tab, and run error checking to correct Windows, if window appears saying check is not necessary, select check disk anyway. This may take an hour to complete. Hopefully, the Windows OS will be repaired and all system functions reinstated after Restart. Remember to create a restore point when system functions are all reinstated.

Try going to settings and check for updates. Then there should be a section for installed updates so you can uninstall it and fix the issue if its related to updates.
If there's any updates that are optional make sure to install them.
