How to fix the issue of Windows 10 Not Detecting Your Second Monitor? – Guide
There are many different factors that can prevent Windows 10 from identifying a second monitor, but it’s an easy solution when you know the basics.
Windows 10 makes it easy to connect a secondary monitor to your setup to increase productivity. However, sometimes your system may fail to detect the second monitor due to hardware or software reasons.
Fortunately, solving this problem is easy. Let’s explore the various ways to help you troubleshoot external monitor connection issues in Windows 10.
Basic troubleshooting Tips to fix when secondary monitor is not detected
Most of the time, it’s the basic elements that keep your PC from detecting a secondary monitor. So, before we delve into the more technical aspects of troubleshooting this guide, follow these tips to see if you did the basics right.
If you have followed all the steps and the secondary display is still not working, please follow the additional steps outlined below.
1. Configure multiple monitor settings in Windows 10
Windows 10 can automatically detect all monitors connected to your system. However, you must enable the displays manually in the settings.
As discussed in the basic troubleshooting part, click Project in the action center and select the Extend or Duplicate option to activate your secondary video.
Alternatively, go to Settings > System > Display. Scroll down to the multiple monitors section, click the drop-down menu and select the Duplicate or Extend option.
If it’s already set to Extend or Duplicate, change the settings to something else and then reverse the changes to see if that helps.
2. Force detection of older monitors
Older monitors aren’t always good with auto detection feature. Fortunately, Microsoft offers a force detection feature in Windows 10 to help you find and activate connected monitors.
To force detection of multiple monitors:
Once detected, make sure the Multiple Monitors drop-down list is set to Extend these monitors or Duplicate these monitors. If you set it to Show only on 2 or Show only on 1, only one of your monitors will be active.
If you see a message that says “Another monitor was not detected”, go to the next step.
3. Check Device Manager for hardware changes
Windows 10 usually automatically detects and installs drivers for a newly installed device. However, if for some reason the detection fails, you can manually scan the installed devices in Device Manager.
In Device Manager, click Action and select Scan for hardware changes.
Windows will check your system for connected devices and install the necessary drivers. Once this is done, your secondary monitor will detect and function without problems.
4. Update the video adapter driver
Your system may fail to detect the second monitor if you run an outdated version of the video adapter drivers.
New computers with an updated operating system come with a generic video adapter. This is a temporary setting to allow you to install pending driver updates after setup up your PC.
To get the necessary updates, go to Settings > Updates & security > Windows Update. Download and install all pending Windows and third-party updates. You can also update video drivers in Device Manager.
To update your video adapter driver:
If Windows has not found any updates through Device Manager, there are other ways to update your graphics driver/video adapter in Windows 10. Make sure you follow the guide and install the latest graphics drivers available for your system.
How to Reinstall video adapter drivers in Windows 10
If updating your graphics drivers does not help, you can reinstall your video adapter to fix the problem. Here it is how to Knife.
- Open Device Manager and expand the Display Adapters section.
- Right-click your video adapter and select Uninstall Device.
- Click Uninstall. Click Yes to confirm the action if prompted by UAC.
- Restart your computer and check if Windows automatically detects the monitor.
Otherwise, open Device Manager, click Action, and select Scan for hardware changes. Then follow the onscreen instructions to complete the installation, if applicable.
How to Rollback Graphics Driver in Windows 10
