windows 10 not detecting second monitor

Hi GamingVexed -

Thank you for your response and I apologize that the methods did not work. Let's try to perform System Restore, if it won't work as well, let's try In-place Repair. Please follow the steps below.

Method 1: System Restore

• System restore is where it will take your computer settings back to an earlier point in time where everything is working fine.

1. Open the run box by pressing Windows Key + R and type rstrui.exe then press enter.
2. System restore windows will open. Normally it will suggest a restore point(Sometimes it doesn't), if it does, select the 2nd option to select more restore points.
3. Select your desired restore point date and time.
4. Once selected, hit next and finish.

Windows will restart itself to start system restore. System restore might take some time to complete and it is very important that system restore must not be interrupted during restore process as it might damaged the operating system. System restore will take at least 20 minutes or more depending on the content of the computer and the changes on the settings that was done prior to the date selected. System restore will also removed application , updates and drivers installed prior to the date selected.

DISCLAIMER:

System Restore is a recovery tool for Windows that allows you to reverse certain kinds of changes made to the operating system. System Restore is used to return important Windows files and settings—like drivers, registry keys, system files, installed programs, and more—back to previous versions and settings. Being said all applications and changes made prior to the date selected will be removed and needs to be re-installed if its needed.

Method 2: In-Place Repair

• In-place repair/upgrade or repair reinstall is a process of re-installing Windows without touching any of your applications or personal files. In this way if there's any data corruption, damaged system files or missing system files on your computer, this repair will fix or repair them.

To start we need to download an ISO file of Windows 10 and save it to your computer. Please follow the instruction on the link below to create an ISO file

After the ISO is created, follow the instructions on the link below created by PaulSey, Microsoft Agent, on how to perform repair install on your computer.

This process will take some time to complete so you need to be very patient in waiting until the process completes. Once done , restart your computer and check if the issue is resolved.

Did you made any changes on your computer before the issue occur? Is this the first time the issue occurs? Let's try the methods below and check if any of the resolves fixes the issue.

Method 1: Perform SFC Scan and Repair Windows Image

-This process will perform scan for any corrupted system files or integrity violation and will attempt to repair it along with the Windows Image.

* sfc /scannow

* DISM /Online /Cleanup-Image /CheckHealth

* DISM /Online /Cleanup-Image /ScanHealth

* DISM /Online /Cleanup-Image /RestoreHealth

Quick note: While the command is running, it's expected to see the process stuck at 20 or 40 percent. After a few minutes, the process will complete successfully.

Once you complete the steps, the Deployment Image Servicing and Management tool will connect to the Windows Update servers to download and replace any damaged files in the local image for Windows 10 as necessary.
