Mirror Hall

Use Linux devices as second screens

flathub_appstream · draft · May 24, 2026 description in en

Description

Mirror Hall is an experimental app that aims to turn any Linux device into a second monitor. It is designed on both desktop and mobile devices, and supports both hardware-accelerated and software-based encoding to stream video efficiently. Mirror Hall makes use of a new, experimental GNOME feature to create virtual monitors, and requires UDP traffic to be allowed by the network and firewall. Support for other desktops will be added once a standardized API exists.
