I needed this to connect my laptop's HDMI output to my old flat screen TV that doesn't have HDMI inputs. Actually yes, but in the back and the TV is on the wall so it's quite difficult to get to. There are RCA inputs on the side of the TV. So that converts the HDMI output to the RCA input. Requires USB power with included cable to connect to PC USB port. Or I had a cord that plugged into an outlet that worked. If you need to convert the HDMI output to an RCA input, this works great.
