Duet Display for Windows

When a laptop screen fills up with open windows, an iPad or phone can serve as an extra display. Duet Display connects a Windows PC with another device for extending or mirroring the desktop, and it also offers tools for remote access and drawing.

Extend a PC display

With Extend, a tablet or phone (Apple or Android) becomes an extra monitor for the PC. Keep one app on the PC display and move another to the connected device—for example, leaving a document in view while using the second screen for reference material or chat.

Duet is software-based, so the display connection does not require a separate dongle or adapter. The mobile device runs Duet as well, pairing it with the computer whose desktop it will show.

Mirror and control screens

Mirror shows the computer’s display on another device, which suits sharing the current screen. Duet also has a Cast & Control workflow for showing an iPhone or iPad screen on a Mac or PC and interacting with it using the computer’s keyboard and mouse.

Drawing and remote access

Drawing Tablet lets you sketch on a supported tablet and see the strokes in illustration software on the PC. Remote Access reaches your computers and mobile devices from elsewhere over the internet.

• Extend adds a second display to the computer.
• Mirror duplicates a display for sharing.
• Shared Keyboard & Mouse lets one keyboard, mouse, or trackpad control two computers.

System requirements: Windows 10, Windows 11
