Ever find something on your computer, smartphone or tablet that you want to show to others on your HDTV? There are a couple of easy ways to set this up.
If you use a Mac and iOS devices (iPhone and iPad), an Apple TV is a good way to go. At $99, the Apple TV is a small set-top box that connects to your TV through an HDMI input. Once connected, you'll be able to take advantage of the AirPlay button in the Mac's menu bar, and when playing media in iOS, to send content to the TV wirelessly.
