OpenDisplay: The Perfect Duo screen companion
Disclaimer: I am not associated with this app or developer.
So I've been looking for a wireless way to extend/mirror onto the Duo but Sidecar isn't compatible and the Mac mirroring is only in closed mode. I just happen to come across this post and it's been pretty good: reddit.com
Features:
- Works in both closed and open, portrait and landscape
- Mirror and extended mode works
- Very easy to set up
- Open-source: peetzweg/opendisplay
Why use this at all?
- Put your mail/Outlook on the side
- Put your Spotify on it
- Slack? Discord? Stream Deck display control?
- Presentation mirroring away from the laptop
Hopefully this helps someone out there.

opendisplay - peetzweg/opendisplay - can make a old iMac's screen useful again. In my case, a 2015 27" iMac can be used as a monitor for my modern Mac laptop, connected via ethernet cable.
if you own an iPad and you use it as an external screen check peetzweg/opendisplay ...
It can help using the external screen as portrait mode 👨💻 which is not supported via mac by default

Looking for alpha testers: iPad as an extended second screen over USB on Linux X11 (open source, GPL)
I've been building OpenDisplay for X11: it turns an iPad into a wired, extended second monitor for a Linux X11 desktop. Plug in the cable, open the app on the iPad, and the desktop extends onto it. Tap, drag, long-press right-click and two-finger scroll work on the iPad.
It's now in alpha, I use it daily on my own machine, and I'm looking for people to try it on theirs. Reports of what worked are as useful as bugs.
Why I built it
- I didn't want to depend on old, unmaintained apps or repos.
- I didn't want something as heavy as Sunshine/Moonlight just for a second screen.
- I didn't want a dummy plug: a spare video port on the computer becomes the iPad's monitor.
It stays as native as possible: the kernel's own video port, X11's RandR, the GPU's hardware H.264 encoder, stock usbmuxd over the USB cable, and the unmodified OpenDisplay iPad app as the receiver. When the iPad's screen is still it uses almost no CPU (~0.1–0.3 % of one core; ~13 % of one core while it changes continuously, on an Intel HD 530).
Requirements (please check before installing)
- Linux Mint 22 / Ubuntu 24.04 or newer, in an X11 session (not Wayland). Mint 21 / Ubuntu 22.04 / Debian 12 can't install it.
- A free video port: an empty HDMI socket, or a DisplayPort socket that accepts HDMI adapters (DP++). On X11 an app can't create a monitor from nothing, so this is a hard requirement. Why
- GPU: tested on Intel (HD 530). AMD should work for the monitor but the encoder is untested. NVIDIA's proprietary driver can't do this.
- iPad with the OpenDisplay app (TestFlight) and a USB data cable.
Install
1. Download the .deb from Releases.
2. Double-click it, click Install, enter your password.
3. Open OpenDisplay for X11 from the app menu and turn it on. Plug in the iPad, unlock it, tap Trust, open the app.
Nothing runs as root: the only privilege is a 2-line udev rule letting the plugdev group switch spare HDMI ports on/off. Uninstall from your software manager.
How to test and report
- Checklist of things to try: docs/alpha-testing.md
- Report on GitHub with the Alpha tester report or Bug report form: open an issue
- Please attach the diagnostic report: in the app, Help → Copy diagnostic report (glance over it first; the log can name your computer and iPad).
- Security problems: privately, via the repo's Security tab, please.
Known limits: X11 only, one iPad at a time, Apple Pencil works as a finger (no pressure yet), no audio. USB-C-only and DisplayPort-only machines are untested and most likely won't work.
Can you trust it? Every release is built by GitHub Actions from the tagged source, is reproducible, and ships with a SHA256, an SBOM and a signed build-provenance attestation you can check yourself. TRUST.md lists everything it can access and how to verify a download.
Repo (GPL-3.0): cray2015/opendisplay-x11
Huge thanks to the OpenDisplay iPad app. It's the stable foundation this builds on.
Happy to answer questions in the comments!
