Kramer AD-RING-11 Multi-Format HDMI Adapter Ring for Conference Room Presentations

The Kramer AD-RING-11 HDMI Adapter Ring is a stainless steel ring that keeps three essential display adapters — DisplayPort (M) to HDMI (F), Mini DisplayPort (M) to HDMI (F), and USB Type-C (M) to HDMI (F) — securely attached to your HDMI cable and instantly accessible for any presenter. It eliminates the hunt for the right adapter before a meeting starts, delivering a clean, always-ready BYOD presentation solution for any HDMI-equipped room.

For IT managers and AV integrators seeking the best HDMI adapter ring for conference rooms, the AD-RING-11 addresses the most common laptop and mobile display connections in a single compact accessory. Whether connecting a modern MacBook via USB-C, a Windows ultrabook via DisplayPort, or an older Mac or PC via Mini DisplayPort (Thunderbolt), the ring puts the correct adapter at every presenter's fingertips. This makes it an ideal fit for boardrooms, huddle spaces, classrooms, and training rooms where BYOD connectivity is a daily requirement.

Built around a durable stainless steel ring, the AD-RING-11 clamps directly onto HDMI cables ranging from 3mm to 9mm in diameter using the included ABS cable clamp and foam rubber inserts. The adapters are passive — requiring no external power — and the security loop keeps everything in place between sessions, protecting the investment and ensuring the next presenter inherits a complete, organized setup. Adapters can be added or swapped using the Kramer TL-RING tool kit (sold separately), making the AD-RING system fully modular for evolving room requirements.
