The Sony Bravia KDL-40V4100 is a 40-inch LCD TV that delivers 1080p HD video and provides 4 HDMI inputs for the highest-quality picture with its connected viewing sources, Bravia Link to facilitate operation with other Sony components and a number of other features and options. One of those features is picture and picture (P&P), which allows you to view two different channels on the screen side by side, and picture-in-picture (PIP) for viewing a PC signal along with TV programming. Both can be activated with the proper commands from the remote control.
Connect your PC to your Sony Bravia TV, using the connection type supported by your PC. Most will provide at least one of either the HD15 or DVI output, or HDMI as well. Purchase the appropriate cable--and adaptor, if necessary--and attach it from the PC's output to the matching input on the rear of the TV. Take any steps necessary to route the video signal to an external monitor, such as pressing "Fn" and "F5" simultaneously.
Connect the TV's viewing source--i.e., cable or satellite--using the "Cable/Antenna" input, as this input must be used to access PIP. Press "Input" on the remote control and set the TV to that input or that of the PC.
Press "Options" and use the up or down arrow key to highlight "P&P or PIP" and press the "Plus" key to select it. This will establish the PC's video in the main window and the TV channel being viewed in the sub-window.
Press the channel up or down button or enter a channel by number to change TV channels in the sub-window. Press "Options," use the up or down arrow key to highlight "Audio Swap" and select it to change the audio source--TV or PC.
Press "Options" and use the up or down arrow key to highlight "Exit P&P or PIP" and then the "Plus" key to exit PIP mode.
Consult your user's manual for further operating instructions and details on the various features and options available with your Sony Bravia TV.
