About this app

ExtDisplay uses your Android phone or tablet as an extra display for a nearby Mac or Windows computer.

What this app does
• Extended display: install the ExtDisplay desktop app on your computer, then drag windows onto the phone or tablet and keep working there. It is a second screen, not a screenshot viewer.
• Find the computer: the app discovers a computer running ExtDisplay on the same Wi-Fi, and can also connect over USB.
• Touch control: tap and swipe on the phone to control content on the computer.
• Local video: frames travel between your computer and this device on the local connection. They are not uploaded to our servers.
• No ads and no cross-app tracking.

How to use it
1. Install the desktop app from https://extdisplay.link on your Mac or Windows PC.
2. Open ExtDisplay on your phone, then connect over the same network or USB.
3. Move a window onto the new display.

This Android app is the free receiver. A desktop license, if you need one, is handled on the website. Questions: reikyzhang@hotmail.com
