Compatibility & Applications
Typical Devices
USB-C laptops and tablets with DisplayPort Alt Mode, including Windows ultrabooks, MacBooks and iPad Pro, connected to HDMI monitors, wired network, USB peripherals and memory cards.
Typical Use
Hot desks, home offices and meeting rooms where one cable should connect a laptop to displays, network and peripherals, and charge it.
Selection Tip
Dual extended 4K displays need MST support, which macOS does not provide; Macs mirror the same content on both HDMI outputs. Use your laptop's own USB-C charger for power pass-through.
