The Twin Picture feature is available on select models of Sony TVs. It makes it possible to watch a TV show and a second video source at the same using either Picture-in-Picture (aka PIP) or Picture-and-Picture (aka P&P).
Picture-in-Picture places the main source across the entire screen and a second source on a small sub-window that you can move from corner to corner. You can also view a PC input as the main image.
IMPORTANT: PIP is not available with a PC input. Also, the available combination of two pictures varies depending on your region or country.
Picture-and-Picture places the two video sources side by side. You can even adjust the sizes to strike exactly the right balance.
NOTE: In both Twin Picture modes, one source originates from the internal tuner while the other comes from an external video input.
