How to exit split screen on your computer

Split screen lets you see two windows side by side, but closing it depends on which operating system you use and how you opened it. On Windows 10 and 11, you can drag a window away from the edge, press the Windows key plus an arrow key to toggle it off, or straightforward maximize one window to collapse the split. On Mac, you close split screen by moving your cursor to the top of the screen, clicking and holding the green full-screen button in the window's title bar, then dragging the window away from the edge.

The method you use matters because some ways of closing split screen leave both windows open (just no longer side by side), while others might close a window entirely if you're not careful. Understanding which approach works for your situation prevents accidentally losing work.

Key Takeaways

  • On Windows, press Windows key plus the left or right arrow key to toggle split screen off, or drag a window away from the screen edge.
  • On Mac, hold the green full-screen button in the title bar and drag the window away from the edge to exit split view.
  • Maximizing a single window collapses split screen on both systems without closing either window.
  • If you use a third-party app to manage windows, check that app's settings or menu to close split screen, since the standard methods may not work.

Closing split screen on Windows 10 and 11

The fastest way to close split screen on Windows is to press the Windows key and the left or right arrow key at the same time. If you're in split screen, pressing Windows + Left or Windows + Right will toggle the split off and return to a normal single-window view. Both windows stay open — you're just no longer viewing them side by side.

If the keyboard shortcut doesn't work, you can drag the dividing line between the two windows to one edge of the screen. Move your cursor to the middle where the two windows meet until you see a resize cursor (a double-headed arrow), then drag all the way to the left or right edge. The window you drag toward will collapse, and the other will expand to fill the screen.

Another option is to click the maximize button (the square icon) in the title bar of whichever window you want to keep. This expands that window to full screen and closes the split view. The other window remains open but hidden behind the maximized one.

Closing split screen on Mac

On Mac, split screen is called Split View, and the way to close it is through the green full-screen button in the window's title bar. Move your cursor to the very top of the screen where the window's title bar sits. Click and hold the green button (don't just click it once), then drag the window away from the edge of the screen toward the center. The window will exit Split View and return to a floating window you can resize and move freely.

If you want to keep one window in full screen and close the split, you can also swipe left or right with three fingers on your trackpad to switch between the two split windows, then press the Escape key or click the red close button to exit Split View entirely. Both windows will remain open on your Mac.

What happens to your windows when you close split screen

When you close split screen, both windows stay open — you're not closing the programs themselves, just the side-by-side view. After you exit split screen, one window will be maximized or in focus, and the other will be behind it or minimized, depending on which method you used.

If you want to see both windows again without split screen, you can click the other window's icon in the taskbar (Windows) or use Mission Control (Mac) to switch between them. You can also resize and position windows manually by dragging their edges and title bars, which gives you more control over how much space each one takes up.

If split screen won't close

If the standard methods aren't working, you may be using a third-party window management app like PowerToys (Windows), Rectangle (Mac), or similar software. These apps sometimes override the built-in split screen behavior. Check the app's menu or settings — usually accessible by right-clicking the app's icon in the system tray or menu bar — and look for an option to disable or exit split view.

On Windows, if you're using PowerToys Snap Layouts, you can disable it by opening PowerToys Settings, clicking the FancyZones tab, and turning off the toggle. On Mac, if you're using Rectangle or a similar app, open the app's preferences and look for a way to deactivate the current layout or close the snap view.

If you're still stuck, try restarting your computer. This clears any stuck window states and returns your display to normal. After restart, your windows will be in their default state, and you can open them fresh without split screen.

Preventing accidental split screen in the future

Split screen often happens by accident when you drag a window to the edge of the screen or press a keyboard shortcut without meaning to. On Windows, if you want to prevent this, you can turn off the snap feature entirely. Open Settings, go to System, then Multitasking, and toggle off "Snap windows." This disables the automatic snap-to-edge behavior.

On Mac, you can disable Split View by opening System Settings, clicking General, scrolling to the bottom, and unchecking "Allow windows to be tiled by dragging near the top of the screen." This prevents Split View from activating when you drag a window to the edge.

Frequently Asked Questions

Does closing split screen close my programs?

No. Closing split screen only closes the side-by-side view. Both programs stay open on your computer. One window will be in front, and the other will be behind it or in the background. You can switch between them using the taskbar or app switcher.

Why does my split screen keep coming back?

This usually happens if you're accidentally dragging windows to the screen edge or pressing Windows + arrow keys without meaning to. Turn off snap in Windows Settings under Multitasking, or disable tiling in Mac System Settings under General to prevent this.

Can I close one window in split screen without closing the other?

Yes. Click the close button (X on Windows, red circle on Mac) in the title bar of the window you want to close. The other window will expand to fill the screen. This closes only the program you selected, not the split view itself.

What if I'm using a monitor with split screen built in?

Some monitors have a Picture-by-Picture or Picture-in-Picture feature that displays two inputs side by side. This is different from your computer's split screen. To close it, use your monitor's menu button or remote control to access the display settings and turn off the feature. Check your monitor's manual for the exact steps.
