New HCX AI Processor
At the heart of this Panasonic 40 inch TV is an intelligent new processor. Delivering accurate colour, contrast and pin-sharp clarity, the processor works with the panel to produce the best picture – whatever the genre. The AI (Artificial Intelligence) processor detects the content and adjusts the setting to suit. Watch sports, for example and the TV recognises this and selects the best settings for fast-moving action.
HDR Bright Panel Plus for super-sharp images
Once the signal has been analysed by the powerful HCX AI 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.
Local Dimming Pro – enhanced contrast
Working in conjunction with the HDR Bright Panel Plus, Local Dimming Pro 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.
Dolby Atmos and Cinema Surround for immersive sound
Compatible with Dolby Atmos sound, this Panasonic TV creates a more immersive, enveloping sound. Fitted with a 20 watt amp, the 40JX850B produces room-filling sound. For even more immersion, select the Cinema Surround setting, or use the HDMI eARC or optical digital output to add a soundbar or base.
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-40JX850B also offers multi-format HDR, including 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.
Smart TV made easy with HomeScreen 6.0
The latest version of Panasonic’s HomeScreen makes all the smart functions even easier to access. When selecting content from your favourite streaming apps, the system offers thumbnail images, making it easier to find your favourite programme. Support for Google Assistant and Alexa means you can also find content via voice command. The new My Scenery feature offers a selection of background images and videos.
Search, stream and play
When it comes to Smart TV flexibility, the TX40JX850B 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.
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.

Rated 5 out of 5 by Pete PGR from A Very Good 40" Television I bought this set a couple of weeks ago via my local branch. I wanted a decent TV not exceeding 43" screen. I like Panasonic products, I use their DVD Recorders, Radios, TV's and even an old VCR. I wanted a dedicated Freeserve TV of modern specification. This 40" TV was recommended by the shop staff and I LIKE IT! The smaller 40" set made it fit better into it's location. Samsung 43" was the second choice, but I preferred the picture quality on the Panasonic. I am extremely pleased with my Panasonic 40" TV. I feel that I have made the correct choice for my needs. Thank You to the Bournemouth Branch for their help and advice.

Rated 5 out of 5 by mikevonbeverley from A very good decision We needed a TV for a small space, so either 40" or, at a pinch 43". Not much choice at 40" ,but the Panasonic got very good reviews except for some doubt about viewing angles. Paul at Richer Sounds Hull explained the potential problems in enough detail to work out that we would have no problem so we bought. And a very good decision that was. Great picture, adequate sound (better with our sound bar) and very easy to set up. All the connections we could possibly need and then some.

Rated 5 out of 5 by David1241 from Smart TV I decided to replace my tv for one with Freeview Play and other apps. I purchased this Panasonic TV from Richer Sounds as the price was right and it came with a 6 year warranty. The TV was easy to set up, colour and sound is very good.

Rated 3 out of 5 by Shaun M from Picture fades considerably when not viewed face on I’ve had my TV for 3 or 4 weeks and have resisted posting a review until I’ve had a chance to experience it properly and I have a mixed review unfortunately. The TV picture is marvellous face on, but I sat slightly at an angle on a different seat in our living room and couldn’t believe the drop in quality in the colours. When I say I sat at an angle to the TV, it is a slight angle, I’m certainly not looking at the TV edge on!! Just by moving my head to the right while sat in the same position, the colour vividly improves. At a slight angle the colour becomes really insipid. It’s like the difference between a milky and a strong cup of tea. I never experienced this with my previous 8 year old Samsung. I only moved away from Samsung as a protest as I do think their software support has been dire! I can honestly say I’m disappointed with this. Face on the picture is great. I like a documentary and often when a program shows old clips in black and white, the clarity is so good it’s as if the clip had just been made. I watched an old Bond movie from the 70’s and the picture quality was almost too good as it looked too real if that makes sense, so face on its magnificent, but not half as good elsewhere in the room. If your hanging this on the wall in a bedroom I would say it’s perfect, as you would always watch face on, but not perfect for our lounge.
