Panasonic Viera TVs have two types of inputs that make it possible for you to connect a computer: VGA and HDMI. Hook your TV up to a Panasonic Viera to duplicate your display on the larger screen, extend your primary computer's work area or just to view the computer's display on a larger screen.
Because Panasonic Viera TVs have both HDMI and VGA inputs, you can use either VGA or HDMI cables. Almost all PCs come standard with a VGA output; some have a DVI output, in which case you would have to use DVI-to-HDMI or DVI-to-VGA cable. Mac computers have a mini-DVI output, which means you would need to use a mini-DVI-to-HDMI or mini-DVI-to-VGA cable. In any case, the quality of the video that appears on the TV will not be higher than the quality of the output connection. Mini-DVI, DVI and VGA all offer similar, standard quality, while using an HDMI output displays the video in high definition. HDMI cables also carry audio; if you use a VGA, DVI or mini-DVI cable, you will need to use a separate cable to run the audio from your computer to your TV.
Connect the corresponding cable to the appropriate output on your computer. Connect the other end of the cable to an available HDMI input on the TV if you are using an HDMI cable. HDMI inputs can be found in the lower right corner on the backside of Panasonic Viera TVs. Alternatively, if you are using a VGA connector, the only VGA connection is along the lower right edge of the back of the TV. If you are running audio cables from your computer to your TV, you must connect them to the correspondingly-colored audio jack in the Video 2 Input along the lower right edge of the back of the computer, beneath the PC input.
Press the "Input" button on the Panasonic Viera remote to bring up the Input Select menu on the screen. Use the arrows on the remote to select the appropriate input, then press "OK." For example, if you connected your computer to your Panasonic Viera TV via the HDMI 3 input, select the "HDMI 3" input and then select "OK."
Press the "Windows" and "P" keys at the same time if you are using a computer with Windows 7 to bring up a dialog box with options for how to use your TV as an external monitor. Options include "Duplicate," "Extend" or "Projector Only." Alternatively, if you are using a Mac computer, navigate to the System Preferences screen, click "Displays" and then click "Arrangement." Adjust your monitors accordingly or click to select "Mirror Displays."
