While Apple TV has its own Netflix app, using it isn't always convenient. If you are visiting a friend, or if you already have the maximum number of devices registered to your subscription, it's often easier just to stream Netflix from a Mac computer or iOS device to an Apple TV using AirPlay. As of May 2014, this is the only way to stream video with AirPlay. You can't stream from a Windows PC, nor can you stream video to anything except an Apple TV.
Connect an Apple TV to your HDTV using an HDMI cable. Navigate to the HDMI input source with your TV's remote control. Follow the on-screen prompts to connect the Apple TV to your Wi-Fi network.
Ensure the device you use is connected to the same Wi-Fi network as the Apple TV. On an iOS device, launch "Settings" and select "Wi-Fi" to connect to the network. On a Mac computer, click the "Network" icon at the top of the desktop.
Download the free Netflix app on your iPhone, iPad or iPod Touch and log in with your Netflix account. On an Mac computer, open a Web browser and sign into your account.
Select any of the thousands of movies and TV shows on Netflix. Tap or click the "Play" button, then immediately tap or click the "AirPlay" icon, which looks like a rectangle with a triangle at the bottom. Select "Apple TV" from the AirPlay menu. Wait up to five seconds for the device to connect to the Apple TV.
Pause, rewind or fast forward Netflix videos using the controls on your device or the Apple TV's remote control. To adjust the volume, you need to use your TV's remote control.
Don't forget to disconnect your Mac or iOS device from the Apple TV when you are done watching Netflix; otherwise, the next time you turn on the device, it will begin streaming to the Apple TV.
You can also access the AirPlay menu, as well as other media controls, by sliding your finger up from the bottom of your iOS touch screen.
