The actual TV is called a home theater display instead of a TV because it does not have a TV tuner built in. If you use any type of cable service that uses a box (Cox, AT&T, TWC, etc.) you do not need this tv tuner and it doesn't matter. If you use an antennae to get your tv it won't work with this display.
The display comes with a tablet to control it, or you can use your smartphone.
