Producing stunning, OLED picture quality from a smaller screen, the Panasonic TX-42MZ800B delivers big TV performance in smaller spaces.

Small but mighty
The Panasonic TX-42MZ800B uses the smallest OLED TV screen size to deliver a premium viewing experience in smaller spaces. With its compact screen size, this Panasonic 42 inch TV is ideal for not just smaller rooms but also for use as a premium quality desktop monitor. Backing up the top quality screen is a full suite of HDR picture enhancements. These include Dolby Vision, HDR10+ and HLG – making sure you have every format covered. For expert delivery of your streaming services and ease of use, Android TV with Google Assistant is onboard. All this, wrapped by a beautiful, frameless design makes this TV a brilliant all-rounder.

See the difference that OLED makes
Rather than using standard, LED TV technology, Panasonic’s MZ800B range features superior OLED screen tech. With its individually illuminated cells, you get incredible contrast, with inky deep blacks and bright whites. Panasonic’s 4K Colour Engine PRO further enhances colour definition, while the Smooth Motion Drive PRO panel delivers super-smooth motion.

Multi-format HDR support for a stunning picture from all sources
Making the most of its impressive OLED screen, the TX-42MZ800B also offers multi-format HDR support, including Dolby Vision, HDR10+, HDR10 and HLG. Dolby Vision and HDR10+ both deliver scene-by-scene 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.

Great for gaming
Continuing its all-round brilliance, the TX-42MZ800B is equally as impressive with gaming as it is with movies and TV. Select Game Mode and input lag is reduced, making your game play super-responsive. A further bonus for gamers is ready access to TWITCH via Google Play.

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.

Dolby Atmos and built-in subwoofer
Compatible with Dolby Atmos sound, this Panasonic 42” TV creates a more enveloping sound. Thanks to its built-in subwoofer, you also get a deeper, more rounded sound than many of its rivals. For an easy upgrade in sound, simply link to a soundbar via wireless Bluetooth or the HDMI eARC interface.

Enjoy the sumptuous picture benefits that OLED brings, on a smaller screen, with the LG TX-42MZ800B.

Please note, this Smart TV features third party Apps. These Apps may be modified or withdrawn at any time. There may also be a delay in launching some of the featured Apps. Catch-up TV Apps may vary by region. The function and availability of apps is not covered by the manufacturer’s or Richer Sounds’ guarantee.

Rated 5 out of 5 by from Fantastic 👋 I bought this TV a few months ago. It was to replace a 20 year old (yes 20 year old) Panasonic Plasma TV. "Chalk & Cheese", "Night & Day" , there is no comparison. Picture, sound, clarity. Absolutely superb.

Rated 1 out of 5 by from Seriously flawed I have had this for a few weeks. It suffers from severe luminance overshoot on HDR 4k blu rays when the screen brightness is set to any level where blacks are actually black. Having such black levels is basically the entire point of an OLED so having to set the brightness at the same black level as an LCD screen is ridiculous. You might say this is a feature endemic to WRGB OLED screens - fine - this is my only one though so I'm rating this one.

Rated 1 out of 5 by from nothing good to say about it NOT FIT FOR PURPOSE This is the worst Panasonic tv i have ever owned. The previous 3 were great. Got the tv on the 12/2/24 and it worked fine for a couple of weeks then start to update 3-4 times a night. Richer sounds Preston sent out an engineer who did a comprehensive up date and it worked fine for three weeks. Then it started with the same faults. So I was offered replacement set woking on the assumption that they can't all be faulty I got the same tx-42mz800b. how wrong I was. Loses its tv guide regularly and as to be restarted and voices to of sync with picture for no reason.

Rated 1 out of 5 by from Great picture - terrible operating system - awful I bought this a week ago to replace an 8 year old Sony smart TV, it the most disappointing purchase I have ever made from Richer Sounds, the operating system is unstable, the Freeview menu doesn't update, so you have to keep turning it off and on, it randomly changes channel for no reason, if you want to listen to the radio channels it turns itself off after 5 minutes and it's blue screened twice tonight, it's randomly just decided to display pretty pictures of mountains and turned the radio off again. I have attempted software updates, it doesn't seem to respond.

Rated 1 out of 5 by from Panasonic 48" MZ800 OLED TV Great Picture but a terrible operating system. I have has the set up for three days now, I am regretting the purchase. The Freeview guide keeps crashing and doesn't refresh, it changes channel by itself, often to the menu page, it been doing it every five minutes today, so you have to grab the remote to change it back. I have hard wired the ethernet and turned the WiFi off, that made no difference. It behaves worse than the 8 year old Sony TV that I replaced.

Rated 1 out of 5 by from Excellent picture shame about the rest I had to return the TV this particular model has been fraught with problems extremely slow to respond and not capable of receiving updates online. Panasonic repair guy said i was the third that day he had tried to update manually. Bath Manager Tom kindly offered me a deal on two alternatives choose the LG and haven't looked back. Excellent customer service.

Rated 5 out of 5 by from Lovely sharp picture I've had the TV a couple of weeks now. It was easy to set up. The menus are ready to read. Picture is very sharp.
