The flexibility your meeting space needs.

The patent-pending HDMI Adapter Rings from C2G are the perfect addition to conference rooms, huddle spaces, lecture halls or classrooms to make sure that anyone can connect. Available in multiple different configurations, the C2G HDMI Adapter Rings provide ultimate flexibility to fit the needs of any space.

Universal 4K HDMI Adapter Ring

Mounts directly to the HDMI cable, ensuring the adapters/dongles are always within reach with simple setup. The ring slides to the HDMI connector when you need it and slides out of the way when not in use.

  • Each adapter is color coded - making it easy to quickly identify the adapter needed
  • The dongle style adapter gives more flexibility, allowing for better placement when connecting to thin or lighter weight laptops.
  • The optional stopper fits on HDMI cables from 5mm to 10mm in diameter and prevents the adapters from sliding too far down the cable
  • The innovative HDMI Cable Gauge Tool reduces stopper installation time by allowing the right-sized stopper insert for the HDMI cable to be quickly identified
