I think you are asking how to get the stuff on your small tablet to show up on your large flat screen TV.
If your tablet is fairly new, it should have the ability to send everything out as a WiFi signal. My phone (android) has a setting called "cast." This allows me to cast what is on the phone to my TV.
You would have to set it up first on your tablet first, then get your TV to pick up the "cast."
