  • Press ⌃⌘F (Mac) / F11 (Windows/Linux)

Fullscreen mode shows your mirrored device on a clean canvas — ideal for presentations, live demos, and recording without desktop clutter.

Multi-device layout

Mirror several phones or tablets, then open fullscreen to arrange them side by side. Scale each device on one canvas — ideal for comparison demos. To record that layout with custom backgrounds, see Recording in fullscreen.

Backgrounds in fullscreen

Choose a solid color, gradient, macOS wallpaper, transparent mode, or upload a custom image in Settings. Backgrounds apply in fullscreen and in windowed mode — and are included when you record.

Exit fullscreen

Press Esc or use the same fullscreen shortcut again to return to the normal window.
