How To Lock a Mouse to One Monitor

Many people choose to set up a dual monitor setting for several reasons. Typically, when there is a multi-display setup, the mouse can freely move from one monitor to another. But what if this feature is more cumbersome than helpful to you for your current task?

How To Lock a Mouse to One Monitor

If that’s the case, you may have wondered how to lock your mouse cursor to one monitor only. This article will cover the ways you can do that and help you control it.

How to Lock a Mouse to One Monitor on a Windows PC

Thankfully, there are pretty easy ways to lock your mouse on one screen. When it comes to PCs that have Windows 7 or newer versions, you have two main ways of achieving this.

Simplest Way: Operating System Settings

Among all other solutions, many forget the easiest and the simplest one – changing the settings in your operating system directly. If using third-party apps isn’t your thing, this solution is all you may have asked for.

The monitors are usually arranged to stand one by another, and that is why the cursor flows freely between the two along the entire border.

Changing system settings works for Windows 7, 10, and 11, but other Windows OS usually have similar settings. Here is how to do it:

  1. Right-click on your desktop and select “Display settings.”

  2. Go to screen resolution settings to see the alignment of your monitors.

  3. Choose where you want to lock the mouse.

  4. Click on the monitor you want to lock your mouse in and drag it higher or lower, so it stands diagonally.

This way, your cursor will still flow between screens, but only if you drag it diagonally from the edge. This solution fixes most issues caused by a freely floating mouse.

If this is not perfect for you and you want to achieve complete monitor locking, you’ll need to rely on third-party apps.

Lock the Mouse to One Screen Using Third-Party Apps

Most users who want to lock the mouse to one screen use Dual Monitor Tools or the Cursor Lock app. Both tools are free for download.

Lock the Mouse Using Dual Monitor Tools

Dual Monitor Tools is a software tool designed for easier management of multi-monitor setups. To lock your mouse to one screen using this tool, do the following steps:

  1. Launch the Dual Monitor Tools.

  2. In the notification bar, click on the app icon to open the app window.

  3. When you open the app, go to “General” on the menu on the left.

  4. Choose the option named “Lock cursor onto the screen.”

  5. Select “Change.”

  6. A new window will pop up, where you should select “Enable this hotkey.”

  7. Assign the hotkey to this option to a free button combination of your choice.

  8. Click on “OK” and save the settings.

How to Lock a Mouse to One Monitor on a Mac

Mac computers allow you to use almost all Apple devices as second screens. Apple offers many features, options, and ways to customize the multi-display experience on Mac. However, the issue with a floating mouse cursor is the same as for Windows users.

Mac does not have a system-based option to lock the mouse while using multiple screens. There is also a lack of free third-party apps that fix this issue.

For a solution that works, we’ve found EdgeCase on the App Store. It’s a small utility package that prevents moving the mouse between monitors. Unfortunately, it costs $14.99 to purchase.

Alternatively, by simply enlarging the cursor in the OS display settings, you will be able to see the motion of the cursor better. This option might not stop your cursor completely from going to the standing screen. But it certainly will help you control it more precisely and prevent it from floating randomly.

To do this, follow these steps:

  1. Go to the Apple menu and find “System Preferences.”

  2. Click “Accessibility”.

  3. Hit “Display” on the left tab.

  4. Go to the “Pointer” tab in the middle of the right side of the window.

  5. Move the slider to set the size of the Pointer.

There IS a way to lock or keep cursors on their separate displays – in display settings – “Allow your pointer and keyboard to move between any nearby Mac or iPad” can be turned off with a checkbox! This also disables “Push through the edge of a display to connect a nearby Mac or iPad”
Steve Larner says:
I’m not 100% sure, but I don’t think that you’re referring to dual or triple-monitor Mac setups, but are referring to Mac and iPad only features. I tried to find info related to mouse-locking to one monitor scenarios, and even GitHub had a comment in July 2023 referencing the lack of a mouse lock to one monitor feature. Apple website has nothing on locking mouse to one monitor in dual or triple setups besides third-party apps. Other articles that relate to your comment only reference turning it on so you can move the mouse across a Mac and an iPad device, which in turn, would be opposite when off like you state, but only for the iPad/Mac combination.
