Panasonic JX850 Assessment: Likeable Mid-Vary LED

Panasonic is greatest identified for the cinematic picture high quality of its 4K screens just like the JZ2000, however with the JX850 it’s trying to fulfill a slightly completely different demographic with a a lot lower cost. Right here, general panel luminosity is excessive, making this a display screen for vibrant room sports activities and gaming followers.

The extra inexpensive JX- mannequin within the Panasonic steady, the JX850 lacks the 120Hz HDR Cinema Show Professional panel used within the range-topping JX940. It additionally drops Dolby Imaginative and prescient IQ, discovered on that step-up mannequin.

Nonetheless, the TV does boast Filmmaker mode with Clever Sensing, and helps Dolby Imaginative and prescient and HDR10+ Adaptive codecs, along with the HDR10 and HLG (Hybrid Log Gamma). So it’s actually no slacker.

Audio compatibility extends to incorporate Dolby Atmos, which could be routed from the set over HDMI eARC to an exterior sound system. All this with costs beginning at £529 for a 50in mannequin which is the one on take a look at right here.

Design & Construct

The JX850 appears and feels premium for that cheap worth. The display screen has a wafer-thin bezel and sits on a large pedestal, which slots in like two separate ft. The panel itself is positioned on prime of the body, making a novel two-step border; it’s a design trick we’ve seen earlier than from the band, nevertheless it provides a premium flourish.

Edge-lit, it’s slim at simply 63mm, and ideas the dimensions at 16kg with a stand (which, it needs to be mentioned, requires fairly some meeting!).

There are three HDMI inputs, all ALLM (Auto Low Latency Mode), and there’s eARC for sending audio to a soundbar. There’s no help for 120Hz playback which requires HDMI 2.1, so next-gen avid gamers hoping to see their consoles just like the PS5 hit 120fps might want to look elsewhere.

Extra connections embody analogue AV, a digital optical audio output and Ethernet, to help Wi-Fi and Bluetooth. Twin Bluetooth connectivity means the set will transmit to 2 paired headphones concurrently, for personal listening which is neat. There are additionally two USB ports do you have to want them.

The TV comes with a button-heavy distant management that features shortcuts for Netflix, Amazon Prime Video, Rakuten TV, YouTube and Freeview Play.

Specs & Options

The JX850 runs the newest model of Panasonic’s personal good TV portal, my Residence Display 6.0. This new iteration introduces My Surroundings, which permits customers to pick photographs and movies to supply background atmosphere – slightly like  Samsung’s The Body – and likewise comes with an On Timer which lets you set a wake-up name, with channel choice.

The JX850 additionally works with Amazon Alexa and Google Assistant, so you need to use voice instructions to test the climate or information, in addition to management the display screen.

The set additionally has a Freeview Play tuner, which delivers all important channel UK Catch-Up TV companies, together with BBC iPlayer, ITV Hub, All 4, My5 and UKTV Play – and sure, the BBC iPlayer app helps 4K. Nonetheless, there’s no satellite tv for pc tuner choice on this mannequin.

Regardless of the dearth of 120Hz, and VRR (variable refresh charge), the display screen is an honest purchase for console house owners. I measured enter lag at 10.4ms (1080/60) with Sport mode chosen. That must be greater than adequate to maintain you forward of the competitors.

Image & Sound High quality

The JX850 actually makes good on its Vivid Panel Plus promise of upper than common image ranges. The panel has a large color gamut, for max pop.

The set runs Panasonic’s next-gen HCX Professional AI processor, which along with the same old number of picture presets (Regular, Cinema, True Cinema, Sport, Sport, Customized and Dynamic), gives an Auto AI image setting, which is sensible sufficient to detect content material and alter picture parameters accordingly.

Any suspicions Auto AI wouldn’t sensibly steadiness the calls for of films and sport show largely unfounded, and for many customers, this is able to be my really helpful viewing choice. However it does favour picture interpolation, courtesy of Panasonic’s icy clean Clever Body Creation cocktail.

I charge the TV’s HDR efficiency barely above common for its class. Peak HDR brightness was measured simply shy of 500 nits utilizing the Regular preset, inside a 10% measurement window, and the Adaptive Backlight set to Off.

Watch Dolby Imaginative and prescient content material, and the viewing choices change to Dolby Imaginative and prescient Vivid, Dolby Imaginative and prescient Darkish and Dolby Imaginative and prescient Vivid. My desire right here was for Dolby Imaginative and prescient Darkish, because the set is intrinsically vibrant to start out with.

Dolby Imaginative and prescient Vivid appears to rob the picture of distinction and punch. When watched in a room with excessive ambient gentle, Dolby Imaginative and prescient Vivid truly regarded fairly good. Nonetheless, when you choose Dolby Imaginative and prescient Vivid, movement interpolation on its Max setting kicks in, with smoothing clearly seen.

Edge lighting invariably brings points. I famous some backlight uniformity issues, with gentle pooling across the backside of the display screen, however that is solely actually noticeable in sure conditions, for instance when watching a letterbox film. For normal full-screen viewing, the evenness of tone is sort of acceptable.

Panasonic describes the set as having Native Dimming Professional know-how, however this shouldn’t be confused with true native dimming and zone management. It’s truly a reference to some refined gentle management across the fringe of the panel.

The set has a reasonably routine two-channel audio system, powered by 2x10W amplification. Audio modes cowl Commonplace, Music, Speech, Stadium and Consumer. Onboard audio is perfunctory, however not in need of quantity.

The Sports activities preset boosts greens and blues within the picture, and likewise applies post-processing on the audio entrance to create an enhanced sense of atmosphere. It’s fairly efficient.

Helpfully, the JX850 is appropriate with Dolby Atmos, and can route immersive audio out of the set to a appropriate soundbar for extra cinematic sound.


The JX850 is obtainable in 40-, 50-, 58- and 65in display screen sizes (TX-40JX850B, TX-50JX850B, TX-58JX850B and TX-65JX850B), priced at £599, £529, £599 and £699.99 respectively.

You should purchase it from Amazon, Currys, Laptops Direct, Argos, AO and Richer Sounds.

The mannequin on our take a look at bench is the 50-incher. The road is flanked by the JX940 collection (accessible in 55-, 65- and 75in sizes), and the JX800 collection (40-, 50, 58- and 65in).

Panasonic doesn’t promote TVs in North America, or a corresponding mannequin in Australia, though there are similarities with the GX850, accessible in 55-, 65- and 75in fashions (TH-55GX850A, TH-65GX850A and TH-75GX850A).

For extra choices, test our greatest finances TV chart.


In some ways, the JX850 is an atypical LED TV from Panasonic. It’s clearly received conventional LG and Samsung consumers in its sights, providing a efficiency optimised for daylight slightly than late-night viewing.

The model’s HCX Professional AI processor, with its Auto AI image setting, is especially spectacular. I additionally just like the model’s customisable My Residence good platform and the display screen’s general design is the proper aspect of premium.

Its gaming enchantment can be appreciable, offered you’re not fixated on HFR playback, because of its low latency efficiency however there isn’t any 120Hz help right here.

Different small downsides embody a fundamental sound system and a few pooling from the sting lighting, significantly when watching letter-box content material.

Lengthy story quick: the Panasonic JX850 is a wonderful display screen given its higher finances price ticket, and nicely value short-listing.
