MS9129 5.5-inch Desktop Display Solution
A desktop secondary-display reference design based on MS9129 (MacroSilicon USB 2.0 → MIPI). The unit uses a 5.5-inch 720 × 1080 panel as a USB information / monitor screen, mountable in portrait or landscape. It can also work as a standard USB Display, with Windows, macOS, and Android support. Host-side Python themes render HUD-style system telemetry for desk status, gaming peripherals, and lightweight dashboards.
