Muralis: per-monitor wallpaper control for multi-display Windows
Muralis assigns separate wallpapers and sources to each connected display, letting you use local images, slideshows, or live web content per screen. Developed by Aetherishq, the Windows wallpaper manager lives in the system tray and is built with WPF and the .NET framework. It supports Fill, Fit, Stretch, and Center display modes, offers WinGet installation, and targets multi-monitor power users who want automated, fine-grained desktop control.
What Muralis actually does for multi-monitor setups
Muralis treats each display as an independent canvas: you assign a source per screen (local file, slideshow, or web content) and pick a display mode such as Fill, Fit, Stretch, or Center. The app follows a tray-first model, so it runs from the Windows system tray rather than occupying the taskbar. It was built using WPF on the .NET framework, which shapes how it integrates with the desktop environment.
Does it noticeably affect system performance during normal use?
The tool is designed to keep a small runtime footprint, described as a minimalist, tray-based operation that consumes low system resources. It does require the .NET runtime to function, which is a prerequisite for execution. Because it uses modern Windows technologies, it operates within the managed runtime rather than making direct low-level system changes, which limits intrusive behavior during idle periods.
Is Muralis safe to run on a production desktop?
Open-source distribution and WinGet listing increase transparency. The project is hosted on GitHub and appears in the official Windows Package Manager repository, which lets users inspect source code and installation metadata. The app applies wallpapers from local files or web sources and does not advertise system-level modifications; the developer’s open approach provides auditability for users concerned about security or privacy.
Do I need technical knowledge to configure and maintain it?
The app targets power users and multi-monitor enthusiasts, offering granular per-screen configuration that may require manual setup for complex arrangements. The tray-first interface keeps the UI minimal, so users comfortable with configuring sources and display modes get the most value. It's optimised for current desktop Windows releases, which guides expected platform familiarity for installation and runtime behaviour.
Who should adopt Muralis and one clear caveat
Muralis suits power users with multiple displays who value per-screen control and the option to use live web content as backgrounds. Its open-source codebase and WinGet integration help with transparency and installation. Expect a setup step to install or confirm the .NET runtime, and plan for manual configuration when deploying complex multi-monitor layouts. Recommended.
