DisplayPort Alternate Mode over USB Type-C on Android devices enables the transmission of video signals via the USB-C port, allowing connection to external displays such as monitors or televisions. This functionality leverages the versatility of the USB-C interface to output high-resolution video and audio concurrently with data and power delivery. For example, a smartphone or tablet supporting this feature can be directly connected to a DisplayPort monitor using a USB-C to DisplayPort cable, mirroring or extending the device’s screen.
The implementation of this technology offers significant advantages, including simplified connectivity, reduced cable clutter, and support for high-bandwidth video standards. It eliminates the need for dedicated video output ports, consolidating multiple functions into a single physical connection. The ability to drive high-resolution displays makes it valuable for productivity, entertainment, and presentations. Its historical context involves the industry’s move towards standardized interfaces and the desire to maximize the capabilities of USB-C ports.
