DisplayDuo

YOUR TABLET. A SECOND DISPLAY.

A little more room.
A lot more possibility.

Turn your Android tablet into an extended display for your Mac. Keep your work open, your reference close, and your desk simple.

Wi-Fi scroll test: ~57 fps · ~38 ms median latency · ~44 ms p95. Measured over iPhone hotspot (5 GHz), an Apple silicon Mac + Galaxy Tab S11. Results vary by device and workload.

Latency is capture-to-display telemetry with estimated display timing; camera-based measurement has not been performed.

BUILT FOR YOUR WORKSPACE

More screen. Less compromise.

A real second display

macOS treats your tablet as a real monitor. Move a window over and give it its own space, with Retina/HiDPI rendering mapped pixel-for-pixel to the 2560 × 1600 tablet.

Easy on your Mac

Hardware HEVC encoding keeps the work efficient. Streaming used about 5–7% of one CPU core on an Apple silicon Mac for DisplayDuo and the capture process. The WindowServer contribution was not established; results vary by workload.

Text that settles into focus

When the screen stops moving, a high-quality refresh restores crisp text. Scroll, pause, and get back to the details.

A SIMPLE CONNECTION

Two ways to make room.

Connect your Mac and Android tablet with USB-C or over the same Wi-Fi network. For the smoothest experience with heavy content, use USB-C.

A FEW GOOD QUESTIONS

Before you make room.

Is it a real extended display?

Yes. macOS recognizes it as a real second monitor, giving you extra desktop space. Move windows between the Mac and tablet, and arrange the displays in macOS settings.

Do I need Wi-Fi?

Connect with USB-C or over the same Wi-Fi network. If your router blocks device-to-device traffic (AP/client isolation), use USB-C.

Which tablets can I use?

You’ll need an Android tablet running Android 11 or later with a hardware HEVC decoder. The PoC was measured on a Galaxy Tab S11 with a 2560 × 1600 panel. Performance on other tablets may vary.

Does it slow my Mac?

DisplayDuo uses hardware HEVC encoding. Streaming measured about 5–7% of one CPU core on an Apple silicon Mac for DisplayDuo and the capture process. The WindowServer contribution was not established, and results vary with your Mac and workload.

Can I flip the tablet?

Yes. The display works in landscape and can flip 180°, so you can place the cable on whichever side suits your desk.

Does touch input work?

Touch input is not supported. The tablet is a display; use your Mac’s keyboard and pointing device to interact with your work.
