Windows 10: Windows 11 will not detect second monitor

I have 2 Lenovo laptops that were upgraded to Windows 11. External monitors worked for a couple of months. In late 2022, both stopped detecting the monitor. I have had all drivers up to date. In one of them Lenovo replaced the motherboard and ports with still no luck. I have tried different cables, HDMI-USB C adapters and monitors. Has anyone found resolution to this?

Second monitor not detected

Hello,

May we know if you've already tried the suggestion provided by Robert Aldwinckle on forums on this

thread?

If Windows can't detect your second monitor, it's usually a driver problem. It could be due to your video driver being outdated, incorrect or faulty. It's also possible that your monitor driver is causing the problem.

Since the issue occurred after the latest update, it's possible that the video or monitor drivers require an update. Try looking for the updated version of the drivers on the device manufacturer's website and follow their instructions.

If the issue persists, try to roll back the drivers to the last good configuration. To do that, you may follow these steps:

• Right-click the Start button and select Device Manager.
• Right-click your device driver, select Properties, and browse to the
  Driver tab.
• Press the Roll Back Driver option if available, and Windows 10 will begin the process.

Let us know how it turns out.
