Monitor Switch review
A focused open-source service for controlling monitors from Linux, the web, APIs, and smart-home tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Monitor Switch is an open-source, self-hosted service for controlling compatible monitors through DDC/CI. It is aimed at Linux users, Raspberry Pi deployments, and smart-home setups that need monitor control outside the display’s physical controls. The service provides a browser-based web UI, software-based input switching, brightness, contrast, volume, mute, and picture controls. It also supports monitor state and capability polling, making it suited to setups where display state needs to be managed programmatically.
Its main strength is the range of control paths around a focused monitor-control service. Monitor Switch exposes an HTTP API and server-sent events, supports command-line scripting through a shell client, and uses editable YAML monitor profiles. Those profiles are designed to accommodate hardware with incorrect or incomplete capability reporting. This combination gives technical users several ways to connect monitor actions to scripts, services, or custom interfaces without limiting them to the browser UI. The published project description also identifies a reference implementation verified on a Samsung Odyssey G9 with a Raspberry Pi Zero 2 W.
Smart-home integration is a central part of the product’s fit. MQTT discovery and Home Assistant integration can place monitor controls within a wider automation setup, while self-hosting keeps the service on infrastructure managed by the user. Monitor Switch is a strong choice for Linux-based workstations, Raspberry Pi projects, and Home Assistant users who want DDC/CI and input switching in one service. It is less suitable for buyers seeking a formally released product, broad verified hardware coverage, or a general-purpose monitor management suite. Compatibility should be considered carefully when the target display differs from the Samsung Odyssey G9 reference hardware.
Monitor Switch pros and cons
- Where it wins
- DDC/CI controls with software-based input switching
- HTTP API, SSE, CLI scripting, and editable YAML profiles
- MQTT discovery and Home Assistant integration
- Where it doesn't
- Primarily verified with a Samsung Odyssey G9
- Requires a Raspberry Pi connected to the monitor
- Usable project that has not yet been formally released
