Review on Compatible Adapter Digital Connector Projector by Mike Barnett

I'm always surprised when technology works - I don't know why but it never ceases to amaze me. The cable connects to my HDMI TV, my TV's USB port for power, and my iPhone. I turned on the TV, the iPhone showed charging and when I selected HDMI 3 on the TV the iPhone asked if I trust the device - I did and my TV worked. But the image was small and I'm still trying to find adjustments to make it work. And I can't figure out how to send audio through the HDMI cable. Therefore 4 stars - great picture, easy installation, but no sound yet.
