Assuming you have an HDTV, you can get a cable that has a 30-pin connector on one side and an HDMI connector on the other. Put a cable between that end and your TV (with HDMI input), and your ipad will show on the screen of the TV (with the right HDMI input used). There is also a cable with a 30-pin connector and a VGA port and which that you can use a VGA cable and the PC input on your TV. Finally, if you get an Apple TV, your iPad can use AirPlay mirroring to wireless display its screen on whatever TV the Apple TV is connected to.
