Product Description

Each adapter converts the laptop output to HDMI for connection to the room display. USB-C supports DisplayPort Alt Mode video from modern laptops; Mini DisplayPort supports older MacBooks and PC ultrabooks; and HDMI passes through directly for HDMI-equipped laptops. All three adapters support 4K resolution output.

The dongle ring is designed for permanent placement at conference tables, credenzas, or presentation podiums providing a tidy BYOD accessory that replaces loose individual adapters. It pairs with existing room HDMI cables and display inputs without requiring changes to the installed AV infrastructure.
