MS9129 USB 2.0 MIPI Display IC
The MS9129 is a USB 2.0 display IC integrating a USB 2.0 Device controller, data transmit/receive circuitry, and audio/video processing modules. It displays or extends content from PCs, smartphones, and tablets onto a MIPI panel through USB 2.0.
The video output complies with DSI-2, supports 1-port / 2-port MIPI output, and provides a maximum output resolution of 1920×1080p at 60 Hz.

Notes
This page summarizes the supplied MS9129 product information. The stated 1920×1080p at 60 Hz maximum does not establish that each MIPI port can independently deliver that mode simultaneously. Confirm port combinations, panel timing, drivers, and production configuration against the complete datasheet and project validation.
