It connects as a universal plug and play usb peripheral device. Mine is connected to the docking station for my Lenovo laptop at the house and the dock is connected to my TV. Soon as I put the laptop on there and give a few seconds, all works. The first time you plug it in it may need to fetch drivers, but that is a one time quick thing. Good Luck
The K400 Keyboard is built for PC connected TVs, and will not connect directly to a TV. Unfortunately, the only other Logitech TV keyboard, the K600, does not yet function with TCL brand TVs.
