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.

a) Right-click on the setup file of the driver and select "Properties".

b) Select "Compatibility" Tab.

c) Place a check mark next to "Run this program in Compatibility mode" and select the

appropriate operating system from the drop down list.

d) Let the driver install and then check the functionality

  What happens when you try to connect the second monitor?

  Do you receive any error code/message?

  Have you tried to connect the second monitor on a different port?
  

I suggest you to connect second display using a different port available on your PC and check if the second display works. If second display works in other port, then the possible cause for this issue may be discrete video card driver.
