Windows 10: monitor doesnt detect any signal from pc after turning on hdr

I’m using windows 11 and when i proceded to go to settings and turn on hdr my monitor went black and didnt turn back on, I tried turning my pc on and off, using different monitors, but nothing’s working…

:)

 

No option to turn off HDR!!!!!!

Thank you Bernard for your response. But this did not solve the problem. I followed the steps to reinstall the Nvidia Driver and the hdr setting in Windows is still missing (no option to turn it off) and the monitor is still black and not being able to receive a signal. I have tried multiple HDMI cables also. My MSI laptop doesnt have a DVI port so i can only use HDMI. Windows Display settings wont even let me Extend the Desktop due to the monitor not being recognized. The monitor is working because I use it for my Xbox. Now if i plug in the monitor using a HDMI to USB display adapter, Windows recognizes it but not at the monitors resolution, and there is still no HDR on/off button in the Windows Display Setting for that monitor. If i update to Windows 11 will it reset the HDMI display port settings? Will everything be lost data wise?

 

HDR cant be turned on with dual monitors. help please

I Recently bought a HDR capable monitor (electriQ 28" 4K UHD EIQ-284KMB-HDR). I had some difficulty with hdr, but in the end, downloaded VP9 Video Extension to get HDR to work. Since then, when i have HDR enabled on my monitor, my settings are forced to "show only on 1" where 1 is my new 4k monitor. when looking art display settings, my second monitor is tiny, like 1/4th the size of the 1. If i try to change to "extend these displays", either HDR gets turned off, or the 2nd monitor just doesnt turn on. When HDR is turned off and both monitors are on, i cant turn HDR on as it makes the screens flicker then turn back on with HDR still off and games and apps showing no support for HDR.

I have all my drivers up to date both through a 3rd party app and windows update. This is on windows 11

GPU: Rx 550

CPU: i7 9700k

mobo: z390 Gaming Plus

Ram: 3700 MHZ ddr4

I hope this is enough information to help me. I have searched all ovet the internet and it just the stupid things such as restart pc, update drivers, make sure im clicking the right thing etc.

 

Haunted by "HDR-ready display detected" Notifications (Win11)

Hello Sagie D

Welcome to Microsoft Community.

I am aware of the present situation is that you are constantly troubled by "HDR-ready display detected" Notifications. From the description, it seems that you have purchased a new monitor to connect to the computer, but in some cases such notifications will appear.

Can you provide some detailed information, which will help us to further explore this issue:

1. What is the brand and model of your Lenovo Laptop, and at the same time, what is the GPU model of your computer.
   
2. What is the model information of the new monitor? If it is convenient, please try to open the built-in screen control center of the monitor, and observe whether there is an option for HDR signal output, if there is a switch for HDR mode, please turn it off. If you are not familiar with this operation, please check the manual for clearer steps.
   
3. How do you currently connect your new monitor, USB-C / HDMI / DP, which versions of HDMI or DisplayPort does the cable support?
   

"HDR-ready display detected" Notifications generally means that Windows has detected an HDR signal. If the hardware does not support it, it may indeed cause this problem to some extent. If it is convenient, please try to clear the screen cache in the registry. The steps are as follows:

Clear screen cache : Windows key + R key to open the running window, enter regedit to open the registry, find the following directory:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control \GraphicsDrivers

• Right-click to delete the Configuration , Connectivity , ScaleFactors folders in this directory.
  
• After restarting the computer, these three folders will be regenerated, and then connect the external screen.
  

Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click here to view the article.

We always look forward to your information and updates, thank you.
