Windows 10: Why does Windows 11 sometimes not recognize external monitors after updates?

Hi Microsoft Community,After updating to the latest version of Window 11, my laptop sometimes fails to detect my external monitors using HDMI and USB-C connections. it worked perfectly before the update. I tried restarting, replugging, and updating display drivers, but the problem keeps happening randomly after sleep mode or restart.Is this a known issue with Windows 11 updates?Are there any permanent solutions or settings tweaks I should apply?Any help would be appreciated. Thanks!

• The connection is via a cable where one end is a DVI port connected to monitor and the other end is a HDMI port connected to laptop
  
• My other laptop, Dell XPS 15 with Ubuntu 20 - recognizes the external monitor.

Laptop suddenly stopped recognizing the external monitor

Hi,

Thank you for posting your query in Microsoft Community.

To assist you better, I would like to ask if the laptop is unable to recognize only the external monitor or other external devices also.

I suggest you to run the Hardware and Devices troubleshooter by following the steps below:

• Click on the Start button, and type “Troubleshooting” on the search bar.
• Click on “Hardware and Devices”.
• A pop-up will appear, click on the “Next” button and your hardware troubleshooting will start.
  

Hope the information is helpful. Keep us posted on the status for further assistance.

 

Windows 11 update gives problems: stopcode + failure to recognize external monitor + driver problems

My laptop automatically downloaded and installed Windows11, but this resulted in continuous computer crashes, a stopcode all the time, failure to recognize my external monitor and driver problems with at least the display drivers.

Starting up properly is not possible. This continuously results in the stopcode.

The one time I managed to actually get started up, I noticed my external monitor wasn't recognized anymore.

So, I went to Device Manager - display adapters and noticed a 'warning sign' at one of the drivers. The display driver for NVIDIA Gefore RTX 2070 was disappeared in the list, seemingly not recognized. I updated the (basic) display driver, and as a result Windows 11 was totally not working anymore, failed to start up, keeps giving a stop code and red screen. And I couldn't manage to get passed this error, besides downgrading to Windows 10.

So, I reversed the upgrade back to Windows 10 and everything is working just fine. The external monitor is seen, all display drivers are there as normal.

It is possible to get the Windows 11 update without getting into serious computer trouble?

I also don't want to spend hours figuring out what to do. I think an update should just work.

For now, I have blocked Windows 11 from installing, because I don't want to spend my time on fixing unneccessary computer crashes on a normally perfectly fine working high quality laptop.

But maybe Microsoft has ways to (future) Windows 11 updated that work just like they are supposed to do?

My system:

• Processor: Intel Core i7 Octa Core (8) 10875H 2.3GHz (5.1GHz) 16MB Cache
  
• Graphics cards: Nvidia GeForce RTX 2070 with 8GB GDDR6
  
• Intel(R) UHD Graphics
