About this project

The ultimate connection just got better

As TV’s get thinner, HDMI sockets are increasingly being positioned on the underside of devices. Accidental movement or the inherent weight of the cable itself contribute to a growing problem of partial or total connection loss. With custom installations and hard to access connections, a cable working loose can result in costly call-outs and device down-time.

The locking HDMI is designed to maintain a perfect connection at all times, preventing unintentional disengagement by the unique and patented locking mechanism. The uni-body switch allows total control for all receptacle configurations and is both forward and backwards compatible, utilising the existing receptacle configuration.

The product was originally unveiled by HDMI Licensing LLC at the Consumer Electronics Show in Las Vegas and is the world’s first locking solution to pass stringent testing at the HDMI authorised testing centre (ATC).

The product has been appraised by leading TV manufacturers and professional audio visual retailers around the world.
