Can I project my iMac screen onto the TV via an Apple TV?

The HDMI cable is a magical one that lets you hook up your iMac to your television.
Unfortunately, AirPlay is out of the question since it’s limited to iOS devices. But if your Mac has a Mini DisplayPort or Thunderbolt port, you can purchase an HDMI adapter from various third-party manufacturers, like MonoPrice, Belkin, and Griffin, to tether your computer to the television. The Thunderbolt-to-HDMI adapters can even carry sound over the connection, so you don’t have to worry about plugging in an auxiliary cable.
