The listing, NEW HD Mirroring Cable for IPhone Ipad Ipod Touch Samsung Huawei -read description has ended.
Please read full description - only works with some devices. This is a new HD Mirroring Cable so you can play video games and watch Youtube on your cellphone and mirror them onto your HDTV. I tested this on my Samsung J3 phone which is not compatible and it doesn't work, so if your device isn't one of the listed, it will likely not work at all. Also...you must have an HDMI port and a USB port on the back of your TV for this to work. You use your phones data cable and plug your phone into the open port cable, then plug the USB end and HDMI end into the TV. The instructions will guide you from there. If you cannot make it work, try with another data cable. These don't get rave reviews on Amazon and they cost about 15-20 bucks, I think because people have a hard time getting them to work correctly in the beginning.
