4K Ultra HD TV's deliver up to 4 times the Picture Resolution of a normal HD TV to give stunning results when using a 4K source. With their 3840x2160 resolutions 4K Ultra HD TV's make pictures look so detailed and pristine that it makes you feel like you're looking at the real world rather than watching TV! Especially when features like the powerful Quad Core Pro Engine are on hand to tease out every last tiny detail 4K has to offer. As Ultra HD screens use more pixels they can deliver far more picture detail when fed a native 4K video signal. This can come from broadcasters Ultra HD Blu-ray or 4K footage shot on a 4k camera or camcorder. With 4K fine details look crisper while textures are more delicately defined. Of course Ultra HD (UHD) actually refers to a wider range of image enhancements all of which conspire to give us a dramatically improved picture quality. Ultra HD is not just more pixels it's about better quality pixels. If 4K is all about picture resolution then HDR (High Dynamic Range) is about colour contrast and brightness. With a 4K HDR television pictures can offer a greater breadth of colours with improved luminosity and more subtle gradations between deepest black and peak white. Together with 4K HDR TV brings the digital cinema experience into the home for the first time. Panasonic offers a wide range of 4K HDR TVs; all are compatible with HDR content sources. Panasonic 4K TVs support the industry standard for HDR known as HDR10. This makes them compatible with all HDR content sources from 4K Ultra HD Blu-ray to streaming services and subscription TV.
