People prefer using the multi-screen setup with two or more monitors. With Windows 11, many users are facing problems like the second monitor not detected. Well, this issue can sometimes occur due to some random bug or some issue with the monitor or within the settings of your PC. If your Windows 11 is Not Detecting the Second Monitor, then you need not worry about it.
This problem can disrupt your multitasking flow and hinder productivity. In this guide, we’ll be getting into the reasons behind this issue and provide you with comprehensive solutions to get your dual monitor setup up and running seamlessly once again on Windows 11.
Why Windows 11 Can’t Detect Second Display?
There could be several reasons behind Windows 11 failing to detect a second monitor. Compatibility issues, outdated drivers, or even faulty cables can all contribute to this problem. The sophisticated architecture of Windows 11 may require a specific setup to function optimally, and any deviation from these requirements could result in the system’s inability to recognize an additional monitor.
Before diving into detailed solutions, it’s important to perform some initial checks:
- Check Cables and Connections: Ensure that all cables connecting your monitors to the computer are securely plugged in. A loose or damaged HDMI cable can often lead to connectivity issues.
- Monitor Power and Input: Confirm that your second monitor is powered on and set to the correct input source. Sometimes, the simplest oversights can cause major complications.
- Driver Updates: Make sure your graphics card drivers are up to date. Outdated or incompatible drivers can prevent Windows 11 from recognizing your second monitor.
- Restart Your System: Sometimes, a simple system restart can resolve minor glitches and allow Windows 11 to detect your second monitor.
Fix Second Monitor Not Detected on Windows 11
In this article, we’ll look at the possible ways on how to fix Windows 11 second monitor not being detected as a problem.
Many times this problem can occur due to some temporary or random bug within Windows 11. This issue can easily be fixed by restarting your PC. You can try restarting your PC and then check whether the problem is fixed or not. Restarting the PC should probably fix the issue for you, and if it did not, you could move to the next step.
Check The Monitor
The very next step to begin is to check the second monitor you are connecting to. You should check whether the monitor is connected to a power source or not. If your monitor is not connected to a power source, then you may experience this issue.
The next thing that you can check for is the cable connecting the monitor and your PC. If you connect your monitor to your PC using an HDMI cable, VGA cable, USB Type-C cable, or any other, you should check whether the cable is working fine. Also, check whether your PC and your monitors are correctly connected or not.
You can try changing the cable connecting your PC and your monitor and check if that works or not. Also, check if your monitor turns on or not. If you have connected it to the power source, there’s some problem with your monitor if it still doesn’t turn on.
If your monitor and PC have multiple ports for connectivity, then you must try changing the ports. For instance, if there are two HDMI ports on the CPU as well as 2 HDMI ports on the monitor, then you must try changing the ports and then check whether if it works or not.
If that doesn’t work for you, then you should check whether the monitor is working fine or not. If possible, try connecting your monitor to another PC. If the second monitor you are trying to use is faulty, you may face such issues. However, if it works fine on another PC, but not when you use it as a second monitor, you should move to the next method.
Switching Monitor Connections – Effective Fix 
For this method, you’ll need to have two monitors connected to your PC using HDMI cables. Make sure your PC is powered off before proceeding.
- Carefully unplug the HDMI cables from the back of your PC. Remember which HDMI port each cable was plugged into.
- Swap the positions of the HDMI cables. The cable that was connected to the first port should now be plugged into the second port and vice versa.
- Power on your PC and give it a few moments to identify the changes you’ve made.
- During the boot-up process, your PC might take a bit longer than usual to configure the new setup.
- As your Windows 11 desktop appears, you’ll hopefully see both monitors come to life. If all goes well, your extended display should run smoothly.
If the second monitor is still not detected, try restarting your PC once more to ensure the changes take effect. Additionally, you might want to double-check your display settings and make sure you’ve selected the “Extend” option under the “Multiple displays” section.
