Big Picture is a mode of Steam reformatted for use with your TV and game controller, so you can enjoy your Steam games from the comfort of your couch. With the press of a button, Steam displays a new full-screen user interface which has been completely redesigned for readability and interaction on TV.
Big Picture is currently available in a beta version of Steam. This beta is available to all users of the PC version of Steam running on Windows Vista, 7, or 8. Read on for a full list of Big Picture beta system requirements.
To opt into the beta, go to the Steam menu and select settings. From this screen, you can click the change button under the Beta participation heading and select the "Steam Beta Update." Once you’ve committed your selection, Steam will prompt you to restart the application. Once it’s back up and running, you’ll find a BIG PICTURE button near the upper right-hand corner of Steam’s main window. Click this, or if you have a game controller up and running, press its center button to enter Big Picture mode.

The Big Picture beta update is currently available on any PC running Windows Vista, 7 or 8, or any Mac running Mac OS X 10.6 or later.
On Windows, Big Picture mode requires DirectWrite. This is built in to Windows 7, and is available for Windows Vista via SP2 and the Vista Platform Update. These are normally delivered via Windows Update, but if your computer does not have them installed, you can download them directly from Microsoft.
On the Mac, a third-party driver must be used to enable the Xbox 360 controller. A driver is available from TattieBogle.net.
