Windows 11 has that handy feature where you can run dual monitors, perfect for multitasking and getting stuff done. But sometimes they just mirror each other – a bit of a pain if you want to extend your desktop. Fixing this isn’t complicated, but it’s not always obvious where to look either. So here’s a quick rundown that might help, especially if your screens are stuck showing the same thing.
How to Stop Dual Monitors from Mirroring in Windows 11
If you want your second monitor to actually extend your desktop instead of copying the first, here’s what usually does the trick. Often, Windows defaults to mirroring if it’s not sure what to do or if the settings got a bit mixed up. Changing it involves diving into display settings and flicking a switch.
Step 1: Open Display Settings
Hit Start or the search bar, then type Display settings — or just right-click the desktop and choose Display settings. Easy as, even if Windows sometimes throws in some random options.
Step 2: Select System
In the Settings window, make sure you’re in the System section — usually the first tab. This is where all the hardware and display stuff lives.
Step 3: Go to Display
Click on Display if it’s not already selected. Here, you’ll see a diagram of your monitors. This helps you figure out which screen is which — sometimes Windows can get a bit mixed up.
Step 4: Identify Monitors
Hit Identify (the button with a number on each screen). Sometimes Windows numbers them, other times you have to guess based on size or position. Because of course, Windows can make it a bit tricky.
Step 5: Change the Display Mode
Look for the dropdown under Multiple displays. It’s usually set to Duplicate these displays by default. Change it to Extend these displays. That’s all you need — it’ll turn off mirroring and give each monitor its own space.
In some setups, it might say something like “Extend desktop,” but the idea’s the same. Selecting this means you can move your mouse across screens and drag windows around, not just see the same thing on both.
And honestly, if that doesn’t do the trick, a quick restart of your PC can help Windows pick up the new setup. Also, make sure both monitors are plugged in properly and recognised — sometimes a loose cable or driver hiccup causes this.
Tips for Stopping Dual Monitors from Mirroring in Windows 11
- Check Connections: Are both monitors plugged in securely? Sometimes a loose HDMI or DisplayPort causes Windows to revert to default or not see the second display properly.
- Update Drivers: Graphics drivers can be the culprit. Try updating your GPU driver through Device Manager or directly from the manufacturer’s site (like NVIDIA or AMD). Sometimes a quick driver update sorts out display issues.
- Monitor Settings: Some monitors have their own mirror or input settings. Check the on-screen menu — you might need to disable mirror mode there.
- Resolution Settings: If the resolutions are off, Windows might default to mirroring. Adjust the resolution for each monitor in display settings.
- Reboot if Needed: Sounds simple, but a quick restart after changing settings can get Windows to recognise your monitors properly.
Frequently Asked Questions
Why are my monitors mirroring by default?
Usually because Windows isn’t sure what your monitors are or defaulted to a safe setting. Sometimes it’s a driver glitch or a hardware detection hiccup. Resetting the display mode usually sorts this out.
Can I switch back to mirroring if I want?
Absolutely. Just head back to display settings and select Duplicate these displays. Easy to toggle depending on what you’re after.
Will this affect performance?
Extending your displays is generally fine performance-wise. But if you’re gaming or doing graphics-heavy work, running multiple monitors can put a bit more load on the system. Nothing too crazy, but it’s worth keeping an eye on system resources if you notice lag.
What if I don’t see the option to extend displays?
Double-check your connections, update your drivers, and reboot. Sometimes Windows just needs a nudge — especially if it’s not recognising your second monitor properly.
How do I set a primary monitor?
You can drag the monitor icons within display settings to reposition which one’s primary, or select a monitor and click Make this my main display. That’s where your taskbar and start menu will appear by default.

Hopefully that saves someone a headache or two. Windows can be a bit weird, but once you get the hang of it, managing dual monitors is a doddle. Good luck, and may your workspace stay tidy and productive.
