HCX Processor – Hollywood-tuned picture processor
Tuned by an industry expert in Hollywood, this 40 inch 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 analysed by the HCX Processor, 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.
HDR10+ Adaptive – ultimate detail in all lighting conditions
HDR10+ Adaptive takes HDR10 and to the next level, making it the ultimate HDR-type picture processor. HDR10+ Adaptive uses light sensors inside the TV to adjust the picture quality for the best contrast. This improves the picture’s brightness, without ‘washing out’ the depth. You get a consistent picture quality, however light or dark your room is.
Multi-format HDR support for a stunning picture from all sources
As well as HDR10+ Adaptive, the TX-40JX800B also offers multi-format HDR support, including Dolby Vision, HDR10+, HDR10, HLG and HLG Photo. HDR10+ offers 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.
See the picture exactly as originally intended, with Filmmaker Mode
Featuring exclusive technology from Panasonic, Filmmaker Mode makes the best of any movie. Designed in collaboration with filmmakers and Hollywood studios, Filmmaker Mode lets you experience the cinematic vision, exactly as the director intended. Overriding the TV’s own motion and picture processing, Filmmaker Mode presents the correct aspect ratio, colour and frame rate – just as the filmmakers intended. Panasonic exclusively add Intelligent Sensing to Filmmaker mode, so that the picture reacts intelligently to changes in light, automatically giving you the most cinematic picture possible, whether the room is bright or dark.
Android TV for smart TV – including voice control via Google Assistant
Android TV gives you effortless access to a vast range of entertainment streaming apps for near unlimited entertainment. Dive into favourites such as Netflix, Amazon Prime, Disney+ and YouTube or search out a few less well known apps from the Google Play store – the choice is near endless. What’s more, this TV also features the Google Assistant, meaning you only have to ask to locate content, change channel or adjust the volume
Share with Chromecast
Sharing media from your smartphone or tablet is easy with Chromecast built-in. Simply pair your phone and cast what’s on your phone on to the big screen – wirelessly.
Listen with two pairs of headphones, with Dual Bluetooth Connection
New for 2021, Dual Bluetooth Connection lets two of you listen, simultaneously, with wireless Bluetooth headphones. Perfect for immersive listening when the kids have gone to bed, Dual Bluetooth Connection helps keep the action intense, without disturbing others.
Ideal for smaller spaces or as a second TV, the Panasonic TX-40JX800B delivers a big performance from a compact TV.

Rated 3 out of 5 by RobMG from A Mixed Bag I bought this TV as it was the smallest screen available to work with RF headphones. I admit, having not bought a new television in a decade, things have moved on apace. As this was to be used by a tech-shy hard of hearing person used to simpler and smaller screens, the remote alone was a conundrum. Navigating the menus was at first like reading a treasure map in a sandstorm, especially as user-friendly manuals appear to be out of fashion. Without the patience assistance of staff explaining in very simple terms what I had to set up and how, I would have been forced to return the product. (Interestingly, Panasonic tech support were unable to help at all and couldn't even grasp the concept of 2 separate volume controls on 1 TV - thank you Richer Sounds!). The TV works fine in general terms, although its start up is slow and if you're in a hurry to catch the end of a programme, switch on early.. If you planning on using this model with headphones + screen sound and you don't have a degree in semiotics, I recommend seeking assistance. Otherwise, it works fine..finally

Rated 5 out of 5 by Mark DIY from Very helpful I went in store to get some advice and view display TVs for image quality. The OLEDs are excellent, but we wanted 40" max, so not an option. This model met our requirements and was delivered within 3 days (cheapest delivery), so happy.

Rated 4 out of 5 by DL48 from Panasonic TV review Picture and sound are excellent. Spoken word is generally fine for impaired listeners such as me. TV is linked to a Panasonic DVD recorder and a Yamaha sound bar and it takes a very long time (about 1 - 2 minutes) to come on whether you do this using the TV or DVD recorder remote. However, this is not a big problem, just takes getting used to. This is a 40" TV replacing a 15 year old 32" Panasonic TV and takes up about the same physical space.

Rated 5 out of 5 by Rodge28 from Fantastic Picture Quality [This review was collected as part of a promotion.] Wanted to upgrade my telly as it wasn’t 4K. Looking around and this was at great value and doesn’t not disappoint. Easy to set up and when watching a 4K movie or channel the picture quality is excellent! Would definitely recommend!
