Does this HDMI lock securely for a stable connection?
Some HDMI's mention this. I am wondering if this product does, and weather it is better to get one that does lock.
Yes, and actually it can be bent and stressed in a tight spot, while still staying connected without any looseness or tearing. It fits securely in my TV, PC, blu ray player , and my wife's little iPhone connector thingy. (for putting your phone picture on your TV)
