Universal 4K HDMI® Dongle Adapter Ring with Color Coded Mini DisplayPort™, DisplayPort, and USB-C®
4K HDMI dongle ring with DisplayPort Male, Mini DisplayPort Male, and USB-C Male connectors to (3) HDMI Female ports
The C2G30028 is a patented Universal 4K HDMI® Dongle Adapter Ring designed to streamline connectivity in conference rooms, huddle spaces, and lecture halls. This dongle-style adapter provides a flexible solution for thin or lightweight laptops, preventing the device from shifting or unleveling on a tabletop during connection. The C2G30028 features three HDMI Female ports and three specific male inputs: one DisplayPort Male, one Mini DisplayPort Male, and one USB-C Male. Each adapter is color-coded with a dedicated band for rapid identification in high-traffic environments. The integrated pull tab allows for easy retrieval, and the universal cable mount attaches directly to the in-room HDMI display cable. This mounting system ensures adapters remain within reach and slide out of the way when not in use, reducing cable strain and tabletop clutter. This specific configuration is part of the Build Your HDMI AV Adapter Ring Bundle series.
