What am I?

I am sitting on the table. I see only what is directly in front of me. Most of the time I am cool to the touch. I light up when I am powered on. I always get warm when I am powered on, too. People do not have a need for me if I am not on. They do not even look at me while I am off. It gets lonely since I am not used until my owner comes home from work. Most people do not even touch me. I think it is because they are too lazy to get up. People only power me on to watch other people and other things. I am a TV.
