Fix Second Monitor Not Detected on Windows 10 [Solved]
To get more work space or better game experience, you would connect dual or more monitors to your Windows 10. If your second monitor can’t be detected, don’t worry. You’re not alone. Many Windows users are reporting it. The good news is you can fix it.
Why my Windows 10 can’t detect the second monitor?
A compatible and updated display driver enables the successful contact between your Windows 10 and monitors. If the display driver is old or incorrect, your Windows 10 can’t detect the monitor.
How do I fix this error?
Here are 2 solutions you can try to fix this problem. You may not have to try both of them; try Method 2 if Method 1 did’t solve your problem.
Sometimes the new drivers don’t work on Windows 10. So you can try to roll it back to the previously version.
1) On your keyboard, press the Windows logo key and X to invoke the quick-access menu.
2) Click Device Manager.
3) In Display adapters section, right-click on your display device software to select Properties.
4) In Driver section, click Roll Back Driver.
5) Go on to follow the on-screen instructions.
6) When it’s done, reboot your Windows 10 to see if it can detect your second monitor.
If roll back display driver to previous version didn’t serve you, make sure to update your display driver to the latest one.
To update display driver, you can download the latest one from your monitor manufacturer’s website manually. If you are not a tech-savvy, we advise that you use such a 100% safe and helpful driver tool to update drivers automatically — Driver Easy. Under its help, you can say goodbye to driver headaches and delays forever.
You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):
1) Download and install Driver Easy.
2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
3) Click the Update button next to a flagged display driver to automatically download and install the correct version of this driver (you can do this with the FREE version).
Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
4) Restart your computer and check to see if your Windows 10 can detect the second monitor.
That’s all there is to it.
