The patented HD EZ lock by blue echo solutions is the only universal locking HDMI cable adapter on the market. Hd EZ lock works with most HDMI cables and components on the market to secure the HDMI cable in its input, and to eliminate harmful stress on the HDMI input. Hd EZ lock attaches to the component's chassis using the existing screw above or below the HDMI input, or with the included 3M VHB (very high bond) adhesive. Typical installation takes only a few minutes. Once installed, HD EZ lock serves as a strain-relief, eliminating connection problems such as intermittent signal dropouts, typically caused by stress on the internal pins of a female HDMI receptacle or from a loose connection. The patent-pending HD EZ lock is a winner of a CEE 2009 Innovations design & engineering showcase award.
