Windows 10: Second monitor not found after Windows update

I am having issues connecting my second monitor to my laptop. On Thursday 7/15 it detected the monitor and was asked to update during shut down. Today 7/20 it will now not detect the monitor. Have followed all trouble shooting steps from restarting all the way to uninstalling the driver and reinstalling. Laptop: Acer Aspire A515-56Processor: 11th Gen Intel Core i7Display adapter: Intel Iris Xe Graphics Monitor: AOC 2762 27

Second monitor not detected after update

Hi Tom,

There are several reasons that could have caused the issue you are experiencing. One of these is the update you previously performed in Windows, either it was not configured properly by the system or the update components were corrupted. Kindly answer the
following questions for clarification:

• Have you tried updating the monitor and display drivers?
• Have you tried to use another user profile to check if the issue re-occurs?

Furthermore, we suggest that you add the other monitor manually. This is to ensure that the second monitor is still connected after the update. Here are the steps:

• Type connected devices and open Connected Devices on the
  Windows Search bar.
• Click Add devices.
• Select the Second screen.
• Pick one of the 3 options: Duplicate, Extend, and the Second screen only.
• The Duplicate option will duplicate the primary display to secondary display.
• The Extend option will unite two monitors so you can use them both as one.
• The Second screen only option will, obviously, disable primary and use only the secondary monitor.
• Once you’ve chosen the preferred mode, save changes.

We're looking forward to your response.

 

I accidentally hit the update button instead of postpone and now my second monitor does not work.

Hello,

I suggest you to unplug the cable from the monitor and connect to the second monitor, and check if it works.

Also, suggest you to follow the below steps, and check if it helps.
1. Press Windows + X, and select Device manager.
2. Check if the second monitor is listed under Monitor.

Also, recommend you to refer below link answered by
