Mini HDMI end seems a little finicky, if I pull or push a little my display loses connection, until I put it back in the right position. Think of an old phone charger cable that only charges your phone when it is in a certain position. That being said, I mostly just use this for my Oculus Rift CV1 headset as my GPU doesn't have a proper HDMI output. But it works great until the mini-HDMI end twitches. Edit: It stopped working completely after less than 2 weeks of use.
