How to Flip or Flip Your Computer’s Display Horizontally


You’re probably familiar with rotating your desktop if you’re using a multi-monitor setup. To match your screen layout, you can easily rotate your screens 90, 180 or even 270 degrees. However, what if you need to flip or invert your screen?

Even though there is no option to do it in Mac and Windows systems, there are still several ways to do it. So, let’s explore and see how you can flip (not rotate!) your monitor.

Why would you want to invert your display?

The main reason users want to invert or flip their screen is to use it as a teleprompter. With the growing popularity of working from home, more and more interactions in the office are happening via teleconference.

However, you cannot look directly at the camera while using your computer simultaneously. This is because of the usual placement of the webcam above the monitor. You also cannot place the webcam in front of your monitor, as this will block your view. This predicament leads users to look off camera during meetings.

You can create a configured teleprompter to solve this problem, with your screen stretched out under a one-way mirror in front of your camera. This way you can look at your camera while looking at your screen simultaneously.

But to do that, you need to flip your display horizontally, and here’s how to do it.

What do you need

Unfortunately, there is no built-in way to flip your screen on both Mac and Windows. This means that you will have to rely on third-party apps. Also, since an inverted monitor is confusing to use, you’ll probably need a secondary display.

Your main monitor will show the computer while you’re working on it, while the second will show what you see on your main screen but mirrored. Alternatively, you can choose to use a single screen with one side dedicated to your non-reversed app and the other section showing your reversed view.

Invert your screen using UltraMon

Made by Realtime Soft, UltraMon is a multi-screen management software. Although you can try the app for 30 days, you will need to purchase a license to use it after that. It costs $39.95 for a lifetime license, so it’s a one-time purchase.

You will also need a secondary monitor to receive the reverse feed from your primary display. Still, it’s a good option if you plan to use its other features.

To download: UltraMon for the Windows ($39.95, comes with a 30-day free trial)

Once you have installed the UltraMon application, right click on its icon in the taskbar notification area. Then go to Mirroring > Settings… A new UltraMon mirroring window will then appear. From there you can choose what you want to mirror. You can choose one of the following options:

  • One or more monitors: reflects a specific monitor. This is a great option if you plan to use different apps while using your teleprompter.
  • Only one application: reflects a single application. This is the best option if you only want to use one application (like Notepad for a script). You can avoid distractions if you open other apps on your primary screen, as they won’t be reflected on your secondary screen.
  • Part of the office: reflects a specific section of your desktop only. This is a great option if your desktop is static and you want to avoid seeing distractions, like toolbars.
  • The area around the mouse pointer: reflects the area around your mouse. This mode is not recommended because the mirrored screen follows your mouse, making it confusing to watch.

Once you have chosen your preferred mode, click Next > and follow the instructions.

If you chose one or more monitors, you must choose which monitor will display your mirror view from the drop-down list, then you must choose the source display from the menu below. To help you find the right view, you’ll see a diagram showing your views and their location above the drop-down menu. When you’re done, click Next >.

If you chose one requestselect the open application you want to mirror, then click Next >. In the next window, choose the window in which you want your mirror view to appear, then check the box use for mirroring. When finished, click Next >.

After making your choices, you will see a final window. Make sure the option Retractable mirror image to fit the monitor is checked. This ensures that you will see your entire application/monitor in your teleprompter’s view. Also, put a tick on flip the mirror image horizontally.

When finished, press Begin. You will then see your main screen or chosen application appear mirrored on the assigned monitor.

When you are done mirroring your main screen, right click on the UltraMon icon in the taskbar notification area, then navigate to Mirroring > Stop. If you want to use the same previous settings you used, just select Mirroring > Start. Alternatively, if you want to pause your mirroring for a while without deleting the mirrored screen, you click Mirror > Pause.

It’s the perfect solution if you’re not tech-savvy and want something easy to install and remove every time you use it. However, you will have to pay for the app after 30 days. Moreover, it only works with Windows PCs.

But, if you don’t want to pay for an app, use a Mac, or only have one screen, you can use OBS Studio instead.

Use OBS Studio to Invert/Flip Your Screen

Another solution is to capture your screen, mirror it in a screen capture app, and preview the mirrored output. OBS Studio is one such screenshot application. It is free to download and works for Windows, Mac and Linux.

To download: O.B.S. Studio (Free)

Once OBS Studio is installed and open on your computer, go to Sources sub-window. Click on the + sign to add the app or monitor your urge to reverse.

If you want to mirror your entire screen, choose Display capture. If you use this option, you need a secondary monitor to output your display to avoid infinity display. If you only have one monitor, choose window capture to reverse a specific application instead.

After clicking on your choice, select the Create a new radio button in the Create/Select Source the window. Ensure the Make Source Visible checkmark is selected, then press OKAY.

If you chose Display Capture, select the monitor you want to see mirrored in the Show drop-down menu in the Properties of ‘Show Capture’ the window. Don’t forget to put a tick on Snap Cursor option if you want to see where your mouse is. Once you have made your choices, click on OKAY.

But if you selected Window Capture, choose the app you want to view upside down in the Window drop-down menu. Again, don’t forget to tick Snap Cursor to see where your mouse is when viewing it upside down. Once you see your app on the preview screen, click OKAY.

In the main OBS Studio window, you should see your app or screen on the main preview screen. If you can’t see it completely, resize the window by clicking on the little boxes on the colored border. Once the size is set, right click above and choose Transform > Flip Horizontal. Your preview will then be inverted.

To display the inverted screen on another screen, right click on the OBS preview screen, then choose Full Screen Projector (Preview) > [the monitor you want to see the inverted display]. Once done, you will see your main display as mirrored on the screen you have chosen.

But if you only have one screen, click Windowed Projection (Preview). To avoid large black areas in your preview, you should set the output settings to half the resolution of your current monitor. So if you are using a Full HD monitor at 1920×1080, the base resolution of OBS Studio should be 960×1080.

To change the OBS resolution, click on the Settings button in the Controls sub-window. In the Settings windowclick on Video. Then, in the Video menu, type the desired resolution in Base resolution (canvas)then press OKAY.

Resize your preview in OBS to ensure you can fully see your chosen app in the windowed projected preview.

Build Your DIY Teleprompter Screen

You can make your homemade teleprompter now that you know how to invert your display. You can look directly at your camera while using your computer. Your audience will see you looking directly at them in meetings, presentations, and lectures, dramatically increasing your impact.
