Panasonic's TX43GX550B delivers incredible 4K HDR pictures, thanks to the support of multiple HDR formats, such as HDR10 and HLG (Hybrid Log Gamma). The resolution of the screen and the clarity of the picture that is shown is fantastic; HDR displays brighter whites and deeper, richer blacks to give an incredible picture. 4K Ultra High Definition means that the screen will display four times the number of pixels (more pixels means a clearer, sharper picture) than Full HD TVs. So, what you see on screen is smooth, natural motion, incredibly detailed images and breathtakingly lifelike scenery. Panasonic have incorporated a fully customisable Smart Platform into the TX43GX550B, giving you swift access to a huge range of apps, including streaming services like Netflix, Amazon Prime Video (subject to subscription & connectivity) and YouTube. This TV will become the entertainment hub of the home as you enjoy the latest content from streaming providers, rent and watch the latest movie releases, game and stay connected to family and friends via social networking the internet, on your TV. The Panasonic TX43GX550B TV also has Freeview Play; a subscription-free service that lets you enjoy your favourite TV shows from BBCi-Player, ITV Hub, 4oD, demand 5, YouTube and other on-demand services. Freeview Play combines catch-up TV, on-demand services and live television, so watching what you want, when you want, is now easier than ever. With a 7 day scroll back, you can be assured that you'll never miss a second of your favourite shows. With a picture this incredible, you may want to give the audio output a boost with the addition of a soundbar from Panasonic. The sound on this TV is really good but as TV casings have become smaller, so has the space to house speakers. Soundbars are really easy to set up - and more economical than a full speaker system - and will give your TV, films and games an audio experience that matches the impact the amazing screen clarity delivers. And if you want to put this TV at the heart of the entertainment without compromising on floor space, then it can be wall-mounted it or even form part of a Smart Home set up.
