Sony XB90x / X90B (2014) Series

100% of the reviews on Amazon.co.uk give this product a positive rating.

Some seriously awesome and highly advanced speakers ; 3840 x 2160 Ultra HD resolution ; Beautiful and very subtle color rendering thanks to the Triluminous Display ; Comes with Smart TV ; Access to the Sony Entertainment Network ; Comprehensive...

Too expensive for what it offers ; 4K and Triluminous display fails with regular DVD ; Too bulky, thick and heavy ; Motion rendering is lacking ; Needs improvements on DVD resolution

The KD-65 is one hell of a fine purchase as far as 4K TVs go. However, in terms of overall value per dollar spent, you’re probably better off going for something like the Samsung UN65F9000, which offers better motion rendering, slightly better...

Spectacular 2D picture quality ; Best audio ever heard from a flat TV ; Great value by 4K standards ; Supports 4K Netflix streams ; HDMI 2.0 supported

3D not as good as 2D ; No 4OD or ITV Player ; Dynamic Contrast engine can go too far with some presets

Also, slightly ironically given the comments we made about the Cinema 2 mode earlier, we feel you might prefer to use the Cinema 1 preset for watching at least those films that have a lot of dark content. Again, we’ll cover our reasons for saying this...

Bold wedge design ; Superb image performance ; Stereo magnetic fluid speakers

Limited catch-up TV services ; Distracting Twitter app ; It's huge!

Sensational image quality ; Best in class audio performance ; Discovery bar content guide ; Distinctive wedge design

Flickery Active Shutter 3D ; Lacks key catch-up services ; Distracting social view function ; It's huge

Sony's X9005B is currently the big UHD TV to beat right now. Awesome image quality, hi-fi grade sound and stylish design put this premium panel at the front of the 4K pack.

Subtle and natural colours ; Crisp, bright picture ; Superb 4K detail ; Rich, open and detailed sound quality ; Smart features and interface are intuitive ; Stylish finish and excellent build quality ; Easy to use ; Latest 4K tech

DVD and standard definition could be better ; Blacks could go deeper ; Slight graininess on upscaled picture ; Motion could be smoother ; Touchpad remote feels cheap and unintuitive ; Lack of 4K content

There’s plenty we like about the Sony KD-65X9005B, from its stylish build to its intuitive smart features.

Superb image definition; deep blacks and great dynamic range; excellent audio performance; dramatic design; One-flick Discovery bar user interface

Active Shutter 3D at its best only in a dark room; not a full compliment of catch-up

Stunning colours with true blacks, brilliant 4K upscaling, fantastic sound, beautiful wedge design, genuinely intelligent smart features, really easy to use

Speaker design might not suit all, new onscreen Social View Twitter app is somewhat antisocial, 3D isn't perfect - but who wants that anyway?

If you're thinking about upgrading your TV and taking the 4K plunge then you'd be hard pressed to find anything nearly as good as the Sony X9005B.

Overall, the KD-65X8005B is a barnstormer of a 4K bigscreen television. We've seen some great Ultra HD performers this year, but none are so comprehensively satisfying as this new X9, and our caveats remain minor. From design to AV performance, the...

Pictures are top class due to their excellent contrasts, warm colours and deep black levels. The set also produces wonderfully full-bodied sound from its massive speakers.

The smart TV system lacks apps for 4oD and ITV Player, and although the speakers sound great, they make the TV very chunky. Its 3D performance is also a letdown as it suffers from some crosstalk.

Sony's KD-65X9005B produces really stunning picture quality, not just with UltraHD video, but also with Blu-rays and HD broadcasts. Its sound quality is top notch too thanks to its meaty speakers. The chunky design, 3D performance and smart TV system...
