In the creation of images FULL HD 3D in this model involves three main technologies PANASONIC: High-Speed 3D-driver high-speed 3D-driver , Crosstalk Reduction reducing crosstalk and high-speed video processing. Ultra high-speed light emission causes the FULL HD 3D image to be displayed at double the frequency while maintaining optimal brightness. It is designed to prevent false outlines and enhance image resolution. The same technology improves the quality of two-dimensional images as well.

Precise synchronization of the shutters opening/closing in the glasses for each eye minimizes unwanted light leakage to create a realistic 3D effect. Note that the 3D glasses are not included, you will have to buy them additionally.

By recognizing moving objects in the frame, the 600Hz Sub-field Drive technology optimizes the display of moving objects, achieving the sharpest and most natural reproduction.

The static contrast ratio, according to the manufacturer, is

5 000 000:1. Improved cell discharge technology in the new G13 plasma panel is designed to significantly improve image contrast when viewed in a dimly lit room. And the reduction in pre-discharge, which causes unwanted gray tint, is designed to significantly improve black gradation. As a result, everything is done to achieve deep, rich blacks in almost any viewing environment – from a brightly lit living room to a bedroom. All these technologies in this model are designed to provide even in dark movie scenes the clarity and texture of clothing and individual strands of hair.


When playing a 1080i signal from the component input, the resolution was about 630 TV lines.

On a standard definition signal, digital artifacts like combing on moving diagonal lines are not noticeable, though the motion is displayed slightly jerky.

With VIERA CAST technology, you can view photos and movies including 3D images stored on a DLNA-certified media server e.g., a personal computer with Windows 7, DIGA recorder, etc. on your big screen TV.d. connected to your home network. Some photo, video, and music file formats are not supported via DLNA, but they can be played back, for example, from a flash card via the USB input.

As for watching the picture in 3D-quality, we should note some peculiarities. 3D viewing area is 3.2 meters, the total viewing angle is 70 degrees horizontally and 40 degrees vertically. If the 3D glasses are out of the available zone for about 5 minutes, they turn off.
