Panasonic TX-55CX680B 55 3840x2160 HDMI USB 4K Ultra HD LED TV

The generation of high brightness LCD panels are great for boosting colors and vibrancy. But they can only truly improve contrast if you can control their brightness in dark picture areas. Local dimming makes this possible by letting separate clusters of a TV's backlights output different brightness levels, so brightness can be reduced for dark areas without compromising the intensity of bright areas. Cue the Quad Core Pro engine. This cleverly separates the smart TV processing from the picture processing, so the smart elements run faster and smoother while pictures look cleaner, crisper and more refined - regardless of whether they're web streams, broadcasts, Blu-rays or 4K feeds. 4K UHD TVs can deliver up to four times as much resolution as Full HD TVs. As you would expect, this means you can see far more detail and texture in 4K UHD pictures, but colors also look more natural, objects look more solid and almost three dimensional, and the extra detail creates a greater sense of depth. Many describe the 4K effect as feeling more like looking through a window than watching a screen. Especially when all that extra resolution is backed up by the wealth of high-end picture quality features Panasonic brings to its 2015 4K UHD TVs.
