Universal 4K HDMI® Dongle Adapter Ring with Color Coded Mini DisplayPort™, DisplayPort, USB-C®, and Mini HDMI
4K HDMI dongle adapter ring with DisplayPort, Mini HDMI, Mini DisplayPort, and USB-C male outputs for versatile boardroom connectivity
The C2G30289 is a Universal 4K HDMI® Dongle Adapter Ring designed to provide versatile connectivity in conference rooms, huddle spaces, lecture halls, and classrooms. This active adapter ring utilizes a patented dongle-style design to prevent laptops from shifting or sitting unevenly on tables, which often occurs with standard, bulkier adapters. This specific bundle provides four distinct male outputs: DisplayPort, HDMI Mini, Mini DisplayPort, and USB-C, all connecting to a single HDMI Female input. Each adapter is color-coded to allow installers and users to identify the required connection quickly. The ring utilizes a universal cable mount that attaches directly to the existing in-room HDMI display cable, allowing the adapters to slide easily to the connector for use and then away to reduce tabletop clutter. For organized deployment, the system includes integrated pull tabs for quick retrieval and a mounting setup that helps manage cable strain. This active device supports video resolutions up to 4K @ 60Hz, ensuring high-fidelity video for modern digital presentations.
