Product Overview

Once you’ve experienced the jaw-dropping beauty of this 40 inch Panasonic LED TV, you’ll never leave your sofa again. Sit back and fire up your favourite films in beautifully detailed and crystal-clear 4K Ultra HD, whilst HDR Bright Panel Plus works behind the scenes to deliver vivid, lifelike colours. You’ll enjoy top-notch picture quality at all times thanks to dynamic HDR10+, which works alongside the adaptive backlight to adjust the depth and contrast for a super-realistic image. It also includes Dolby Vision, which adds an enormous range of shades and hues, as well as incredibly immersive surround sound via Dolby Atmos®. There’s a wealth of content available online too – just connect it via your home network to enjoy tons of streaming apps and catch up services.

We want you to fully enjoy your new TV, so please be careful when unpacking it – pull it out of the box using the edges so that you don’t damage the screen. If you need to return your TV for any reason, we just ask that you don’t pack the plug in front of the screen as it could damage the TV in transit.

Features we love

Bring Hollywood into your home

Make sure each film you watch looks exactly as the director intended, with a screen that has been fine-tuned by Hollywood professionals. Directors, visual artists and cameramen have tweaked the tech behind your TV, altering features ranging from contrast to the frame rate. So you’ll know you’re getting the true Hollywood experience with every movie night.

A more cinematic experience

Experience cinema-quality viewing thanks to the advanced HCX processor. This clever bit of tech continuously adjusts the contrast and balance on-screen to enhance your favourite blockbuster titles. The result is a picture and colour quality much closer to that which the director intended.

Spectacular colour and contrast brings content to life

HDR technology adds amazingly lifelike colour and depth to your favourite shows and movies for a truly spectacular cinematic experience. But it’s easy to feel overwhelmed by all the different kinds out there, especially since broadcasters and streaming platforms don’t always use the same one. Luckily, this model supports a huge range of HDR formats, including HDR10+ and Dolby Vision, letting you enjoy an enormous amount of content in the best possible quality.

3D sound puts you at the heart of the action

Step inside the action and truly surround yourself in sound with Dolby Atmos. This impressive piece of tech works by recreating audio in 3D so that you’re fully immersed in everything happening on-screen, from high-octane explosions to dramatic dialogue. So whether you’re in for an epic movie night or watching the match at the weekend, you’ll be at the centre of a truly cinematic experience.

A TV that listens

Effortlessly control your TV using your voice with Amazon Alexa or Google Home. This TV connects to your smart speaker or an enabled device, allowing it to adjust the volume or change the channel on command. So when you have your hands full with popcorn, or you’re all snuggled up under a blanket, you won’t have to stop what you’re doing to reach for the remote.

Keep the whole family happy

Never miss an episode of your favourite show with USB HDD recording. The TV’s port allows you to connect an external hard drive, which you can record programmes to by simply hitting the REC button. So when the football clashes with the latest drama series, you can store one for later – saving any fights over the remote control.

Say goodbye to trailing wires

Connect other devices to your TV without the mess of cables thanks to Bluetooth Audio Link. Not only can you sync your TV’s sound with Bluetooth speakers, but you can directly share audio from your smartphone. So whether you’re blaring out your blockbusters through a soundbar, or streaming your music playlists from your phone, you’ll be able to enjoy the freedom of wireless connectivity.

Great TV

Bought this as a second TV having purchased a very similar one from AO a year or so ago. Great TV. Quality is everything you'd expect from Panasonic. Sound, picture etc spot on.


Very pleased with this product. I feel I am living the dream with my new television. The colour is amazing and picture so sharp. Would highly recommend this product.

Great new tv !

Fabulous tv. Picture is great, sound is great; so much better than our old tv. Easy to connect up with games, Youview, & now tv stick. Simple to set up & tune. Be prepared for a bit of self assembly putting the stand together, if you’re doing that bit yourself. However, it was quick, pretty painless & no alan keys involved ( though you’ll need a phillips screwdriver).

had what I wanted and could deliver the next day

found what I wanted at very good price and could be delivered the next day which was a bank holiday Sunday was very happy and delivered in the time frame sent by email to me all in all great service
