Fix Windows 10 Not Detecting Second Monitor [Solved]

To get more work space or better game experience, some users choose to use dual or more monitors. But how if your Windows 10 not detecting second monitor? No worry! If you are facing such issue, this guide is quite for you. 

Commonly , Windows 10 cannot detect the second monitor is due to the incompatible display driver. Follow the ways below to get the correct display driver on your Windows 10.

Note: If Method 1 didn’t help you, try method 2 then.


Method 1: Roll back to previously installed display driver

Sometimes the new drivers don’t work on Windows 10. Thus you can try to roll it back to the previously version.

Open quick-access menu by pressing Windows key + key at the same time.
Then click Device Manager.

Find and expand Display adapters dialog.
Right-click on your display device software to choose Properties.

Click Roll Back Driver under Driver pane.

Go on to follow the on-screen instructions.
When it’s done, reboot your Windows 10 to see if it can detect your second monitor.

Method 2: Update your display driver

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.

1) Download and install Driver Easy.

2) Run Driver Easy and click 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).

After update your display driver, restart your computer and check if your Windows 10 can detect the second monitor.

That’s all there is to it.

    Alright so my 2nd monitor(previously a tv) was working just fine. I unplugged it for something, and then when I put it back in, it won’t detect it at all. Got the No Signal on it. The rollback method did not work at all. Any suggestions on if Driver Easy still does not fix my problem? The TV works but for some reason it’s not getting a signal anymore. If D.E. fixes it, then I’ll update this comment. But suggestions would be welcome!

    THANK YOU! THANK YOU! THANK YOU! I have been struggling my computer randomly ceasing to detect my second monitor for months. Until yesterday, simply deleting my driver software and rebooting did the trick. But after two days of multiple attempts and copious swearing, I finally found your fix in a desperate Google search. It worked like a charm. Color me happy!

    Hello! Roll back is not showing up for me,

    And when I go to update the driver, it’s telling me that it is updated. Any advice?

      Hi, Barb. To get the previous version or the latest version of your driver, you can choose to download from your display adapter manufacturer’s website as we mentioned in the article. For some reasons, Microsoft might not detect the update for you, thus you need to update the driver manually.If you want to save time, you can take a try on Driver Easy.
