    Following the latest Government advice, we’ve had to make some changes to our services.

    We can still collect your old appliance and take it away for recycling. You’ll just need to make sure it’s by the entrance to your property ready for us to collect, as we won’t be able to remove it from any other room in your home.

    We’ll happily take away your old TV for you and recycle it. All we ask is that it’s unplugged and ready to go. The fee for this service relates to the cost of taking your old TV away on our van rather than the recycling service.

Product Overview

Bring the cinema into your home with this 55-inch Sony Bravia OLED TV. With over 8 million self-illuminating pixels individually controlled by the X1 Extreme processor, images are upscaled for truer 4K HDR quality. OLED technology provides genuine black and sharp contrast, while the TRILUMINOS Display draws from a range of hues and intensifies colours for an incredible, lifelike picture. What’s more, with Sound-from-Picture Reality™ the sound is delivered from the entire screen, rather than from the back of the TV, so you’ll hear the explosions and dialogue exactly where they originate from. And since it’s powered by Android, you’ll have access to a huge selection of streaming 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

A cinema in your living room

This TV is an IMAX Enhanced model with Dolby Vision HDR, meaning you’ll enjoy a breathtaking picture with audio to match. IMAX takes care of all the images and sounds, bringing them all up to an incredibly 4K quality. On top that that, Dolby Vision HDR adds another layer of realism with stunning colours and rich contrast. All this comes together to deliver a seriously impressive experience that’ll have you glued the screen.

Never miss a single detail

Motionflow XR helps your TV’s picture stay smooth and sharp even during high-speed action scenes. It works by cleverly popping in some extra frames during a fast-paced sequence, getting rid of any stuttering or juddering in the process. That means you won’t miss out on any key details or have to struggle with annoying blurring when things start to get crazy on-screen.

Precise sound from every angle

This TV uses Acoustic Surface Audio tech to deliver really accurate sound for whatever you’re watching. There are 4 areas on the back panel that vibrate, carrying dialogue and music from the main speaker across the screen to match what’s happening. This means that you’ll always hear things like speech directly from the character’s mouth for a more immersive experience.

Lose yourself in sharp picture full of colour

This model combines a powerful X1 Extreme Processor with a TRILUMINOS screen to bring movies, TV shows and games to life. The processor works behind the scenes to highlight the finer details and cut down on distortion and blurring for a more realistic picture. The TRILUMINOS tech displays a huge range of colours that are bright, vivid and incredibly lifelike. When you add them together, you get an eye-popping picture that’ll really pull you into the action.

Easily almost limitless choice

Easily browse hundreds of streaming and catch-up services with Android TV. This intelligent interface is built-in to your TV and lets you access tons of content, launch apps, and play videos at the touch of a button. As well as being super-simple to use, you can control it using your Android smartphone or tablet by simply downloading the handy mobile app. That means you’ll always have a world of entertainment at your fingertips whenever you fancy a movie night.

Top TV tips

Remember that a TV’s size in inches is diagonal from corner to corner. So, if you're using the stand, you’ll need to check the width of the TV in the product specification to make sure it’ll fit on your furniture. Check the feet too – if they’re at the edges of the TV, make sure they’ll both fit on your TV stand.

Great TV, would recommend! But AO are the greatest company out there!


Excellent product

Impressive Sony AG8

Very good quality picture, plus very impressive sound. Would highly recommend if your thinking of buying a Oled tv.

My wonderful new television

It’s fabulous, colours are amazing and the sound is great without the need for a sound bar. Would really recommend this television.

Great TV.

Awesome TV, easy to set up. I am disabled and was worried about settling it up due to the size and how fragile it was. The 2 lads that delivered it couldn’t set it up or take it out of the box for me but we’re really great and left it in a position for me to sort it. The quality is awesome and really easy to set up.

Fantastic OLED TV for a fantastic price

Great picture quality, one of the most affordable OLED TVs at a reasonable price. No common issues appear like blooming and the colours are fantastic, best colour red on most OLED tvs you can find which has been known to be an issue on some. All the pre loaded apps work well, quality is superb and overall a fantastic product.

Any offers are genuine savings. Because we match the prices of competitors, there is the potential for prices to drop further. We will always offer our customers our price match promise. See terms and conditions.
