Let’s begin with the topic Why Is My Second Monitor Only Mirroring? Mac and Windows computers have two display modes when connected to an external display: Mirror and Extend. The computer monitors duplicate the monitor on the external display in Mirror Mode, allowing you to see the same image on both the Desktop and the projector.

The external display is considered a separate screen in Extend Mode, allowing you to have multiple windows active on the projector and Desktop. It’s simple to flip between the two modes.

Why Is My Second Monitor Only Mirroring?

It’s usually because of the driver. If the monitor driver is outdated or malfunctioning, Windows 10 will be unable to recognize the second monitor. If the graphics driver and monitor driver have been updated, I recommend reverting to the earlier versions. Otherwise, make sure you’re up to date.

Second Monitor Only Mirroring

When the second monitor is not identified, we must determine whether the problem is with the monitor, the cable connecting the two monitors, or the port. I recommend removing your first monitor and replacing it with your second monitor. Connect the first monitor to the 2nd monitor after that. Drivers for graphics and monitors can be found in Device Manager. Follow the steps below to do so:

  1. In the Cortana search field, type Device Manager and hit Enter.
  2. When the Device Manager window pops up, go to Display adapters and right-click the device below.
  3. Choose Properties, the Driver tab, then Roll Back Driver, and follow the on-screen instructions.
  4. Expand Monitors, then right-click and select Properties on the second monitor.
  5. Click the Driver tab, then Roll Back Driver, and follow the on-screen directions.
  6. Update the drivers if the problem persists. You can manually update the driver by going to the websites of the makers of your graphics card and monitor to find fully suitable drivers for Windows 10. You can use the Find command and troubleshoot issues with devices and hardware to search for driver updates automatically. We’d also like to know what brand and model your graphics cards and monitor are.

Ensure That The Refresh Rates On Your Monitors Are Set To The Same

The monitor/display refresh rate is the number of times per second that the visuals on your screen are refreshed. When two monitors are connected to Windows 10 simultaneously, the refresh rate is quite important. Different refresh rates are not supported by all graphics cards simultaneously. If your two monitors’ screen refresh rates differ, your second monitor is unlikely to be recognized.

Update Your Video Driver

If reverting to a previous video driver doesn’t get Windows 10 to identify your second monitor, you’re probably using the wrong one. You can get the correct driver for your video card in two ways: manually or automatically.

Manual driver update: You can manually update your video driver by visiting the manufacturer’s website and looking for the most recent correct driver for your video card. Be careful to select the only driver compatible with your Windows 10 version.

Automatic driver update: Driver Easy can do it for you if you don’t have the time, patience, or PC skills to update your video driver manually. Driver Easy will automatically see your system and locate the correct driver for your specific video card and Windows 10 version, which it will then download and install correctly:

  1. Driver Easy can be downloaded and installed.
  2. Run Driver Easy and select Scan Now from the menu. After that, Driver Easy will check your computer for any problematic drivers.
  3. To automatically install and download the correct version of all missing or out-of-date drivers on your system, click Update All. (The Pro version is required for this, including full support and a 30-day money-back guarantee.) When you click Update All, you’ll be asked to upgrade.) 

Check to see if Windows 10 / Windows 7 can now detect your second monitor after restarting your computer.

Rollback To A Previously Installed Video Driver

On Windows 10, the most recent drivers don’t always work properly. Go back to a prior version of your video driver (also known as a “display driver”) to see if this is the problem.

  1. To open the Run box, hit the Windows logo key and R (simultaneously) on your keyboard.
  2. Press Enter after typing devmgmt. msc.
  3. Right-click on your display device software in the Display adapters section and select Properties.
  4. Click Roll Back Driver on the Driver tab, then follow the on-screen directions.

Note: Whether the Roll Back Driver option is grayed out, you can download a prior video driver for your video card from the manufacturer’s website and install it on your Windows 10 machine, or try Method 2.

  • Restart your computer and verify if Windows can now identify your second monitor.

How Do I Turn Off Mirror Mode?

  • Step 1: Click System after opening Settings.
  • Step 2: Locate Projecting to this PC on the left side and click it.
  • Step 3: Locate and select the Some Windows and Android Devices options.
  • Step 4: From the available options, select Always Off.

Why Is My 2nd Monitor Not Displaying?

To re-establish the connection, restart the computer. Choose the appropriate input port using the monitor’s built-in controls. Examine the signal cable connection between the graphics card and the monitor. The signal line should be cut off at both ends. After waiting 60 seconds, firmly reattach it.


That concludes Why Is My Second Monitor Only Mirroring? When utilizing a PC with numerous displays attached, Airtame will automatically reflect the first of the secondary desktops (i.e., the secondary monitor). Selecting which of the two monitors is the computer’s main display, you can alter which one is being reflected. This article explains how to set up the main display on the various operating systems that the Airtime app supports.

Frequently Asked Questions

Why is the display on my second monitor so large?

Changing the screen resolution on your computer can result in a large display, whether consciously or unknowingly. Click Display settings from the context menu of an empty spot on your Desktop. Ensure you’ve selected the recommended screen resolution from the drop-down box under Resolution.

What’s the deal with my two screens showing the same thing?

Select the Screen Resolution option from the right-click menu on the Desktop. Select ‘Extend these displays’ from the dialog box’s multiple displays drop-down selection. If it doesn’t work, go to the top of the screen and click the Detect button.

Why are both of my displays labeled as 1?

Both monitors must be linked directly to two independent ports; otherwise, if one of the ports is split, the computer will only recognize both monitors as one as both are essentially attached to the same port!

Why are my twin displays switching back and forth?

Check the orientation of your display: The issue could be the monitor’s orientation, which isn’t as prevalent. Look for Display Orientation in the Display section of Windows. To see if this helps, try altering the orientation to something like Portrait, then back to Landscape.
