Mirror Hall for Linux

Use Linux devices as second screens

Overview

Mirror Hall is a Linux app that lets you use your Linux devices as extra screens.

It works on both desktop and mobile Linux devices, making it a useful tool to extend your workspace.

The app supports two types of video streaming encoding: hardware-accelerated and software-based.

This helps Mirror Hall stream video smoothly while using system resources efficiently.

Mirror Hall uses a new, experimental feature from the GNOME desktop environment to create virtual monitors.

This means it currently only works with GNOME, so users on other desktop environments won’t be able to use it yet.

Because it relies on this experimental feature, Mirror Hall is still in early development and might not be fully stable.

Users may notice some bugs or missing features during use.

To stream video between devices, Mirror Hall needs UDP traffic to be allowed through your network and firewall.

This is important to ensure the devices can communicate properly without being blocked.

At the moment, support for desktop environments outside of GNOME is not available.

The developers plan to add this once there is a standard API.

Overall, Mirror Hall is a handy tool if you use GNOME on Linux and want to turn your device into a second monitor.

Since it is experimental, it’s best suited for users who are comfortable with testing software and troubleshooting basic network settings.

It is a network and utility app designed specifically for Linux users looking to increase their screen space safely.
