Rediscover every detail with 4K X-Reality PRO

Discover a thrilling world of extraordinary clarity with every single pixel enhanced beautifully. Individual parts of each scene are analysed and matched with a special image database that independently addresses texture, contrast, colour and edges. The difference is clear with supremely lifelike detail, whatever you're watching.

IR Blaster – control everything with one remote

The Infra-red (IR) Blaster lets you control other devices in your home from your Sony TV remote. You can use it to control your Set-top box (cable box) with the TV remote controller.

Cinematic S-Force Front Surround

Enjoy an immersive soundstage that pulls you into the heart of the action. S-Force Front Surround mimics the way the brain correlates sound sources to create proper volume, time lag, and sound wave spectrum – using only left and right speaker channels. By naturally emulating three-dimensional sound fields, you'll enjoy rich, high-fidelity audio across a wider listening area.

Sony Bravia 55" Smart 4K Ultra HD HDR LED TV | KD55XE8577SU is rated 4.3 out of 5 by 24.
Rated 4 out of 5 by from All-around great television Fantastic tv with so many features that other and sometimes more expensive tv's just don't have. When comparing to other models in the same price bracket, this was the only one which had features such as the built in Chromecast and dual sat tuners. Not to mention the android os which allows apps and games to be installed to enhance it further. The only negatives about this set are the stand which does not feel sturdy at all and is plastic, unlike previous years which are solid (I have mine wall mounted but I wouldn't trust the stand). Also there can sometimes be a slight lag when using the remote control for things like volume input. I've found that by linking the tv with the Amazon echo through the Logitech harmony resolves this issue.

Rated 4 out of 5 by from Excellent Picture Quality, not so good upscaler We bought a XE8596 55" TV. It is a brilliant television both for picture quality and ease of us. It integrates very well with our bluray as well as the PS4 Pro. The only thing that is a little under expectation is the picture upscaler when the signal coming in is 560p or 720p. Other TV's we went to see seem to upscale much better. This is not an issue as in the future less and less programs will be in lower resolution. When in 4K (i.e. PS4 PRO) we think the picture quality is much better than the equivalent Samsung and Panasonic we have seen.

Rated 5 out of 5 by from XE85 4K HDR TV I went into a lot of detail to buy a 4K tv And the TV I bought ticks all the boxes

Rated 5 out of 5 by from Android operating system makes this one a rwinner! So pleased I went for this one. Not only does the picture quality exceed expectation but the Android operating system makes jumping from Sky to Netflix to Amazon Prime makes this fast and easy. Sound quality is good (better than a lot of flat screens) but I would still recommend attaching and using a Sony soundbar and woofer for films to really maximise the experience

Rated 5 out of 5 by from It is indeed a smart tv Believe it or not, our old Toshiba retro tv died after nearly 20 years of faithfull service. But we have seen the light and been brought i to the 21st century in the entertainment world. Loving the clarity of picture, the voice activation, apps the lust is endless. Still miss the sound from my old 'retro tv' but in all other areas it beats it hands down.
