At home or away
Your Wi‑Fi at home, Ethernet at the desk, or a network across town — wherever your devices can reach each other directly. When they can't, Remio tells you right away.
✦Second display Pro
iPad, iPhone, MacBook, Windows laptop — every device is a second display.
Any device you pair with Remio — a tablet, a phone, the spare MacBook, the Windows laptop, even an Apple TV — becomes a real extended display for your Mac, Windows PC or Linux computer. Up to three at once, at home or on the go. Drag a window across and it stays there.

✦Laptops too
That spare MacBook? Your Windows laptop? Monitors again.
A laptop already has a great screen. Remio puts it to work: open Remio on it, pick your computer and choose Use as second display, and the laptop becomes one more monitor beside the one you're working on.
- MacBook or any Mac — macOS 15 or later. It goes full screen and keeps its display awake while it's showing.
- Windows laptop or PC — Windows 10 (1809) or later. The window is titled “Second display”, so you can tell it apart.
- Pair once with the computer's QR code or Device ID and PIN, then start it from the computer's card or its details whenever you sit down.
Mix platforms freely: a Windows laptop extends a Mac, and a MacBook extends a Windows PC or a Linux desktop.
✦A morning at the desk
Your iPad on the right. Your iPhone on the left.
You sit down at your Mac with an iPad and an iPhone that already have Remio. Thirty seconds later you have three screens.
- Pair once. Install Remio Host on the computer and pair each device with its QR code or Device ID and PIN — the same pairing you use for remote control.
- Tap “Use as second display” on the computer's card in Remio on the iPad. The Mac gets a new display; its own screen stays on.
- Do the same on the iPhone. A third screen appears. Tap Arrange displays… and the Mac's display settings open so you can place each one where it really sits.
- Drag windows across. Docs on the iPad, chat on the iPhone, your work in the middle. Tap and type on any of them.
Works the same with a Windows PC or a Linux desktop as the computer — and with an Android phone or tablet, a Mac, a Windows PC or an Apple TV as the extra screen.
✦Direct connection
Straight between your devices.
Your second display talks straight to your computer — across your Wi‑Fi at home, and from the café, the hotel or the office too. Never through a relay or Remio's servers, not even while it reconnects.
Nothing in the middle
No relay, no cloud between your devices. Like every Remio connection, it's end‑to‑end encrypted.
Rides out connection blips
If the connection drops, the computer keeps the display for 10–15 seconds while it comes back. If it doesn't, the windows return to your other screens.
Nobody takes over
While devices are acting as second displays, a remote‑control request from another device is declined — your screens never go dark under you.

Stop alt‑tabbing. Park it on a device.
Whatever you keep glancing at goes on the tablet, the phone or the laptop beside you. Touch, keyboard, files and clipboard work on every second display.

Editor on the computer, documentation on the iPad, build output or a terminal on the iPhone.
Design & editing
Canvas or timeline in the middle, tool palettes or the preview on the iPad beside it.
Chat & mail
Slack, Teams or mail on the iPhone — in the corner of your eye, off your main screen.
Dashboards
Monitoring, analytics or a calendar on an old tablet that would otherwise sit in a drawer.
✦Questions
Common questions
How many second displays can one computer have?
Up to three at the same time. The first second display on each computer is free. The second and third need Remio Pro ($1.99 a month, 7-day free trial) on the device that adds them.
Does second display work over the internet?
Yes — straight between your devices. At home it connects across your Wi‑Fi or wired network; away from home it connects straight to your computer whenever your devices can reach each other directly, and Remio Host opens the way on routers that allow it. The picture never goes through a relay or Remio's servers. When there's no direct way from where you are, Remio tells you — and Remio's remote control still reaches your computer from anywhere.
Which devices can be a second display?
iPhone and iPad on iOS or iPadOS 18 or later, Android phones and tablets on Android 12 or later, Macs on macOS 15 or later, Windows PCs on Windows 10 (1809) or later, and Apple TV on tvOS 18 or later.
Can a MacBook or a Windows laptop be a second display?
Yes. Install Remio on the MacBook (macOS 15 or later) or the Windows laptop (Windows 10 version 1809 or later), pair it with your computer once, and choose Use as second display. It works across platforms — a Windows laptop can extend a Mac, and a MacBook can extend a Windows PC or a Linux desktop.
Which computers can use one?
Mac, Windows and Linux computers running Remio Host 3.2 or later. On Linux, Remio adds displays on GNOME and on X11 desktops.
What happens if the connection drops for a moment?
The computer keeps the display for about 10–15 seconds while the connection comes back. If it doesn't, the display is removed and its windows move back to your other screens — like unplugging a monitor.
Can someone take over my computer while I use second displays?
No. While other devices are acting as second displays, a remote‑control request from another device is declined with a clear message, so nobody can darken your screens under you.
How is this different from Apple Sidecar?
Sidecar turns one iPad into a display for a Mac signed in to the same Apple ID. Remio works with Mac, Windows and Linux computers, with iPhone, iPad, Android, Mac, Windows PC and Apple TV as the extra screen, needs no Apple ID — you pair once with a QR code or a Device ID and PIN — and runs up to three extra displays at once.
When can I use it?
Right now. Second display is part of Remio 3.2 — install Remio Host 3.2 or later on the computer and Remio 3.2.2 or later on the iPhone, iPad, Mac, Android phone or tablet, Windows PC or Apple TV you want to use as the extra screen. Using it away from home needs the latest Remio Host and the latest Remio app. See the changelog for what's in each release.
More screens, from what's already on your desk.
Install Remio Host on your computer and Remio on your iPad, iPhone, Android, Mac, Windows PC or Apple TV, pair once, and tap “Use as second display”. The first one is free.
