multiple monitors stopped working after upgrading to windows 11

Question

Laptop was connected to multiple monitors and running windows 10. After upgrade to windows 11 the laptop does not see the devices when trying to update in display. Error message is "we did not find another display"

Answer 1

After upgrading to Windows 11, if your laptop is not detecting multiple monitors, it could be due to several reasons related to display settings or driver compatibility. Here are some steps you can take to troubleshoot the issue:

1. Check Physical Connections: Ensure that all cables are securely connected to both the laptop and the monitors.
2. Display Settings: Press Windows + P to open the Project menu and select a display mode (e.g., Extend, Duplicate, or Second screen only). This can sometimes reinitialize the connection to the monitors.
3. Update Graphics Drivers: Ensure that your graphics drivers are up to date. You can do this through Device Manager:
   • Right-click on the Start button and select Device Manager.
   • Expand the Display adapters section, right-click on your graphics card, and select Update driver.
4. Check for Windows Updates: Sometimes, additional updates may be available that can resolve compatibility issues. Go to Settings > Update & Security > Windows Update and check for updates.
5. USB-Attached Monitors: If you are using USB-attached monitors, be aware that there may be issues with display configuration retention after rebooting. This is a known issue with Windows 10 and 11 when using USB video adapters, which may require specific drivers or settings adjustments to function correctly.

If these steps do not resolve the issue, you may need to consult the manufacturer's support for your laptop or the monitors for further assistance.
