Vizio TVs have a picture-in-picture mode as well as a picture-outside-picture mode. The former shows the input from another video source in a smaller window on the screen, and the later shows pictures from two video inputs side by side at the same size. It’s important to note that Vizio TVs can only display certain types of input through the PIP/POP display when the TV tuner is being used as the primary display. Writer Bio
