Duet Display

Duet Display is software that transforms your spare devices into functional second displays for your computer. It works by creating a direct connection between your main computer (Mac or PC) and your secondary device (iPad, iPhone, Android tablet, or even another computer), turning that device into an extended monitor. The connection can be made through USB cable for maximum performance or wirelessly for convenience.

What sets Duet Display apart is its focus on performance with minimal lag, even when used wirelessly. The software includes several specialized modes beyond basic screen extension: you can use your iPad as a drawing tablet with pressure sensitivity, mirror your iPhone screen to your computer for presentations, or remotely access your desktop computer from another device. It also offers shared keyboard and mouse functionality between connected devices.

This tool is particularly valuable for people who work across multiple devices or need extra screen space while traveling. Digital artists can use it to turn their iPad into a graphics tablet, remote workers can access their office computer from home, and professionals on the go can create a dual-monitor setup with just their laptop and tablet. The business version supports team deployments with centralized management.
