How to Fix Windows 11 Not Detecting Second Monitor (5 Ways)

Many individuals prefer employing a multi-screen setup featuring two or more monitors. However, users of Windows 11 may encounter challenges such as the failure to detect the second monitor. This issue may arise due to random bugs, monitor-related problems, or settings discrepancies within the PC. If you’re experiencing the dilemma of Windows 11 not detecting the second monitor, there’s no need for concern.

This problem can disrupt the flow of multitasking and impede productivity. In this guide, we will delve into the reasons behind this issue and offer comprehensive solutions to ensure your dual monitor setup is seamlessly restored on Windows 11.

Why Windows 11 Can’t Detect Second Display?

The failure of Windows 11 to detect a second monitor may stem from various reasons. Compatibility issues, outdated drivers, or faulty cables could all contribute to this problem. The intricate architecture of Windows 11 may necessitate a specific setup for optimal functioning, and any deviation from these requirements might lead to the system’s inability to recognize an additional monitor. Before delving into detailed solutions, it’s crucial to perform some initial checks:

Check Cables and Connections: Ensure all cables connecting your monitors to the computer are securely plugged in. A loose or damaged HDMI cable can often cause connectivity issues.

Monitor Power and Input: Confirm that your second monitor is powered on and set to the correct input source. Simple oversights like this can lead to major complications.

Driver Updates: Ensure your graphics card drivers are up to date. Outdated or incompatible drivers can hinder Windows 11 from recognizing your second monitor.

Restart Your System: Sometimes, a simple system restart can resolve minor glitches and enable Windows 11 to detect your second monitor.

Fix Second Monitor Not Detected on Windows 11 

In this article, we will explore potential solutions to address the issue of Windows 11 not detecting the second monitor.

Restart PC

Frequently, this issue arises from temporary or random bugs within Windows 11. Resolving it is often as simple as restarting your PC. Give restarting a try and assess whether the problem persists. Typically, a PC restart should resolve the issue, but if it persists, you can proceed to the next step.

Check The Monitor

The immediate next step is to examine the second monitor to which you are attempting to connect. Verify if the monitor is properly connected to a power source, as the absence of power may lead to this issue. Additionally, scrutinize the cable linking the monitor to your PC, whether it’s an HDMI, VGA, USB Type-C, or any other type. Ensure the cable is in good condition. Check the correct connection between your PC and the monitors.

Consider changing the cable connecting your PC and monitor and observe if it resolves the issue. Verify whether your monitor is turning on. If it’s connected to a power source and still fails to turn on, there may be an issue with the monitor. If both your PC and monitor have multiple ports, attempt changing the ports. For instance, if there are two HDMI ports on the CPU and two HDMI ports on the monitor, try switching ports to see if that resolves the problem.

If these steps don’t yield results, assess the overall functionality of the monitor. Connect it to another PC if possible. If the second monitor exhibits issues on another PC, it may be faulty. However, if it functions correctly on another PC but not when used as a second monitor, proceed to the next method.

Switching Monitor Connections – Effective Fix [2023]

For this procedure, you’ll need two monitors connected to your PC using HDMI cables. Ensure your PC is powered off before proceeding.

  • Gently unplug the HDMI cables from the back of your PC, taking note of which port each cable was connected to.
  • Swap the positions of the HDMI cables. The cable originally connected to the first port should now be plugged into the second port, and vice versa.
  • Power on your PC and allow it a few moments to recognize the changes you’ve made.
  • During the boot-up process, your PC may take slightly longer than usual to configure the new setup.
  • Once your Windows 11 desktop appears, both monitors should ideally activate, and if all goes well, your extended display should function seamlessly.
  • If the second monitor is still not detected, try restarting your PC again to ensure the changes take effect. Additionally, double-check your display settings to confirm you’ve selected the “Extend” option under the “Multiple displays” section.

Update Graphics Driver

If the monitor is functioning properly, the likely issue lies with an outdated graphics driver. To resolve the problem of the second monitor not being detected in Windows 11, consider updating the graphics driver using the following steps:

  • Open the Start menu and search for “Device Manager,” then open it.
  • In the Device Manager, double-click on “Display adapters” to view the list of graphics cards installed on your PC.
  • Right-click on each graphics card listed and select “Update Driver.” Repeat this process for every individual display adapter.
  • Once the graphics drivers are updated, restart your PC.

Updating the graphics driver should effectively address the issue.

Reinstalling Graphics Driver

If updating the graphics driver did not resolve the issue, consider reinstalling the graphics driver with the following steps:

  • Click on the start icon to open the start menu, search for “Device Manager,” and open it.
  • In the Device Manager, double-click on “Display adapters” to view the list of graphics cards installed on your PC.
  • Right-click on each graphics card listed and select “Uninstall device.” Repeat this process for every graphics card to uninstall the graphics driver.
  • Restart your PC.
  • Return to the Device Manager, and click on “Scan for hardware changes” in the Action tab. This action will reinstall the graphics driver on your PC.

Reinstalling the graphics driver through these steps may help resolve the issue.
