Windows 10: Second monitor not detected

Split from this thread. I have problem after Windows 11 installation [with second monitor not being detected]. I noticed this after the 22H2 update. I have tried all options above.The same laptop, same hdmi port, same cable works with a brand new ASUS monitor we purchased. But doesn't work with older monitors like the DELL E2211H monitor.To make the issue even more interesting if I close the DELL laptop monitor and reboot with the external monitor connected the DELL logo appears on the external monitor DELL E2211H then after the spinner comes on the external monitor the screen goes black

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 It could be due to your video driver being outdated, incorrect or faulty.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.
