ScreenWall turns old devices into a shared display wall

ScreenWall is an application designed for repurposing legacy hardware. It enables old smartphones and tablets to function as part of a shared display. Users can connect multiple devices to form a continuous visual wall. The app synchronizes content across the linked screens. ScreenWall aims to extend the life of devices that would otherwise be discarded. It offers a low‑cost alternative to dedicated digital signage. The solution is targeted at hobbyists and small‑scale installations. Future updates may add more customization options for the display wall.
