Energy Rating 
HCX Processor – Hollywood-tuned picture processor
Tuned by an industry expert in Hollywood, this Panasonic TV delivers a picture that’s faithful to the colour and detail originally intended. The powerful HCX processor features 3D LUT, HDR and 4K remaster tech to accurately reproduce the picture – just as the filmmaker intended.
HDR Bright Panel Plus for super-sharp images
Once the signal has been processed by the powerful HCX device, it’s sent to a screen that does it justice – HDR Bright Panel Plus. Using extra-bright LED backlights, this screen goes brighter and therefore enhances contrast, giving superb levels of contrast – even in conditions of high ambient light.
Local Dimming – enhanced contrast
Working in conjunction with the HDR Bright Panel Plus, Local Dimming gives more control over the picture contrast. By being able to dim particular areas of the image, contrast is enhanced, making images look even more natural and lifelike. The processing is so fast and seamless, you’ll notice nothing except an incredible sense of image realism.
Multi-format HDR support for a stunning picture from all sources
If you’re wondering whether to choose between a TV that supports HDR10+ and one that supports Dolby Vision, you no longer have to. This Panasonic TV supports them both! HDR10+ and Dolby Vision offer scene-by-scene HDR mastering for the truest, most accurate HDR picture technology. Each scene is optimised, meaning the maximum amount of detail is shown – even in the brightest or darkest moments.
Dolby Atmos for enveloping sound
Compatible with Dolby Atmos sound, this Panasonic TV creates a more immersive, enveloping sound. For even more immersion, select the Cinema Surround setting, or use the HDMI ARC or optical digital output to add a soundbar or base.
HomeScreen 5.0 for easy navigation and voice control support
The latest version of Panasonic’s HomeScreen makes all the smart functions easy to access. When selecting content from your favourite streaming apps, the system now offers thumbnail images, making it much easier to find your favourite programme. Alternatively, support for Google Assistant and Alexa means you can find content via voice command.
Search, stream and play
When it comes to Smart TV flexibility, the HX800B series has all the features you need. As well as the popular streaming apps, the TV also offers a full web browser. DLNA certified streaming makes it easy to transfer music and video files from your home computer, laptop or NAS drive to the TV. Also standard is Swipe and Share functionality. Swipe and share lets you use the Panasonic Remote TV app for smartphone media sharing. By using the app on your smartphone or tablet, you can easily stream pictures, 4K videos and music straight to the TV - no cables required.
Freeview Play for easy access to catch-up TV
This Panasonic also features Freeview Play. This combines catch-up TV, on-demand services and live television to make it easy to watch what you want, when you want. It's free from subscription and compatible with existing broadband services, while BBC iPlayer, ITV Player, All 4 and Demand 5 are available without having to open specific apps, giving effortless scroll-back TV (requires broadband Internet connection with a minimum speed of 2Mbps).
Bluetooth Audio Link
Featuring a two-way Bluetooth Audio link you can use the Bluetooth output to link up with your headphones or Bluetooth speaker. Alternatively, send Bluetooth sound from your smartphone, tablet or other Bluetooth enabled device to the TV and listen through the TV’s speakers.
