Two projectors.
One wide desktop.
Two minutes.
VideoWallaby edge-blends two, three or four projectors into one screen your Mac or PC thinks is a single display. Drag the join. Hold your phone still. Put any app on the wall.
Direct download. No store, no subscription, no account to run it. Try it free with the test grid; pay once when it's your wall. Edge blending and the wallaby are included.
Open the app with the projectors on. Start the clock.
That's the rule we build to: a stranger with two lit projectors should have a wall they can use, and stop again, inside two minutes. The four steps are the whole interface.
Tick the ones that make the wall
Big numbers flash on each screen so you know which is which. The screen with your controls stays yours.
Side by side, stacked, or 2 × 2
Drag to swap. Slide the join. VideoWallaby matches resolutions and refresh rates for you.
Hold still, or drag the corners
Every change shows on the projectors as you make it. Undo is always one click.
Put any app on it
The wall is just a display now. Press B to black it out. Stop puts your screens back the way they were.
Hold still for five seconds. That's the calibration.
The projectors play a short loop: all white, all black, then each projector alone, then each one's 46 dots. Your phone watches, through its own camera app. Nothing to install.
- VideoWallaby finds every projector's outline and dots and sets the corners. No photos to take one by one, no points to check.
- A slightly shaky hand is fine: the loop plays twice and the difference is used to correct it.
- Works at any overlap, from edge to edge up to half a picture.
- If the camera moved or a projector didn't show up, it says which. You try again.
Edge blending. Up to four screens, 1920 × 1080 each.
Where two projectors overlap, both light the shared band: one fades out across it as the other fades in, so their light adds up to one even picture and the seam disappears. That's edge blending, and it's how every join on this page works. The overlap is adjustable from 0 to 50% on every shared edge, and a blend curve makes the fade softer or sharper. At 5% the desktop comes out like this.
On a Mac the wall is a virtual display VideoWallaby adds. On Windows it's a display from a bundled driver, added the first time you start a wall, with Windows' permission, and removed when you stop. Copy-protected video from streaming apps stays black, by design of those apps.
One ticket. Every wall you run.
Buy it once, sign in with the email you used, and it unlocks on your Mac and your PC. No subscription. Updates in this version included.
The wallaby keeps the screen you work from in its pouch. Your controls never get swallowed by the wall.
Crash reports
On by default, so we can fix what breaks. A crash sends what the app was doing: no names, no pictures, no files. Off in Advanced settings.
Setup steps, if you say yes
Asked once: which steps you reach and how long a wall takes. Nothing that identifies you. Off until you answer.
Your wall is yours
Camera frames, photos, profiles and the phone page never leave your computer unless you press Send on a failed alignment. The whole policy.
