DisplaySplit makes Windows see each part of your ultrawide as its own display, so fullscreen, screen sharing and every app behave as if two monitors were on your desk.
Snapping windows side by side only arranges them. DisplaySplit changes what Windows believes is plugged in.
Fullscreen
Video, browser fullscreen and presentations fill one screen instead of stretching across the panel.
Screen sharing
Teams, Zoom and Meet list two screens. Share one at a normal shape and keep your notes on the other.
Taskbar
Each display gets its own taskbar, and Win + Shift + arrow moves a window from one to the other.
Game mode
List your games once. DisplaySplit steps aside while they run, at your panel's full refresh rate.
Without DisplaySplit, fullscreen video stretches across the whole panel.
Nothing on your display changes until the last step, and even then you have 15 seconds to undo it.
The wizard checks your displays and shows what each new screen will measure before anything changes.
Two equal halves, 60/40, a wide centre with two wings, or drag the divider wherever you like.
Every change waits 15 seconds for you to confirm. If you don't, your display goes back to how it was.
Any new layout reverts after 15 seconds unless you confirm that you can see it.
It works from anywhere, even when the app's window isn't visible.
If DisplaySplit ever closes unexpectedly, the split doesn't come back until you turn it on.
The app goes online to activate your licence key and to confirm it once after the refund period. That is all it ever sends.
Better to know now than to find out after paying.

What the installer puts on your PC
It runs in the notification area by the clock.
This is what lets Windows see more than one monitor.
Windows needs it to load that driver. It is unique to your machine and is not shared with anyone.
The driver and certificate are only added when you press Install driver inside the app. Uninstalling from Windows Settings removes all three. If your PC doesn't have Microsoft .NET 10, setup gets it from Microsoft first.
No. Snapping only arranges windows. Windows still sees one monitor, so fullscreen video, games and screen sharing use the whole panel. DisplaySplit makes Windows itself see separate displays, which is why those things start behaving.
You can download it with just an email address and go through setup for free, including seeing exactly how your display would be divided. Turning the split on needs a licence key. If it doesn't suit your setup, ask for a refund within 30 days.
Yes, with game mode. Add a game once and DisplaySplit pauses whenever it is running, so the game gets one full-width display with G-Sync and HDR. The split returns when you close the game.
Any display that is 21:9 or wider, such as 3440 × 1440 or 5120 × 1440 panels. Ordinary 16:9 displays connected alongside are left alone.
Yes. Home, Pro and the other editions of Windows 11 are supported.
Press Ctrl + Alt + Shift + F12 to turn the split off instantly. Layout changes also revert on their own after 15 seconds unless you confirm them, and the split stays off after any unexpected shutdown.
Uninstall it from Windows Settings like any other app. That removes the app, the display driver and the certificate.
The app has no sign-in, no analytics and no usage tracking. When you activate, it sends your licence key and an anonymous ID for your PC to our server, and it checks once more after the refund period. After that your licence is verified on your own PC.
