You actually connect GoTouch to your smartphone, tablet or PC via Bluetooth, and then connect that device to your TV. You have several options to do that:
1.) If you're using an iPhone or iPad, use Apple TV's AirPlay, or connect using a lightning to HDMI cable.
2.) If you're using Android, you can use a micro USB to HDMI cable, or connect via Chromecast or another screencasting device.
3.) If you're using a PC, you can connect it to your TV using an HDMI, VGA or DVI cable, depending on your graphics card and the inputs on your TV.
