Side Screen

Turn your Android device into a Mac second touch display.

Up to 8K • 120 FPS • Under 15 ms

Plug in a USB-C cable or connect over Wi-Fi, and your tablet becomes a real extra monitor: drag windows onto it, keep reference material or chat open on the side, and control the Mac directly with touch or a stylus. Free and open source.

FEATURES

• Up to 8K resolution at 120 FPS — a true high-refresh monitor, not a laggy mirror

• Under 15 ms latency over USB-C, hardware-accelerated H.264/HEVC decoding

• Native touch and stylus input back to macOS, including hover and pressure where supported

• Portrait or landscape, any tablet size

• Resolution, frame-rate and HiDPI controls from the Mac app

• Automatic reconnection in wireless mode

• No account, no ads, no analytics, no internet required — everything stays on your local network

HOW IT WORKS

• Install the free, open-source Side Screen host on your Mac (macOS 13 or later, Apple Silicon and Intel) from github.com/tranvuongquocdat/SideScreen

• Open this app on your tablet

• USB-C: connect the cable and the display appears automatically

• Wi-Fi: scan the QR code shown on the Mac once; the tablet reconnects by itself afterwards

REQUIREMENTS

• A Mac running macOS 13 Ventura or newer with the Side Screen host app installed

• Android 8.0 or newer

• For USB mode: a USB-C data cable. For wireless mode: both devices on the same Wi-Fi network
