Sony A1 review: the Bravia KD-55A1 is the best OLED 4K UHD TV you can get without breaking the bank


The best 55-inch 4K OLED TV to buy, pound-for-pound, Sony's A1 combines dazzling image quality with incredible sound for such a slim panel

Superb image quality ; Amazing Acoustic Surface sound system ; Stylish, minimalist design

We're not in love with Android Smart OS ; Could be due for replacement soon…

Sony KD-55A1 review


Sony's first 4K OLED should have even LG worried...

Beautiful, classy and unique design ; Good sound from its clever, invisible speaker system ; Deep, insightful blacks ; Spot-on skin tones and vibrant colours ; Brilliantly solid, three-dimensional images

No Dolby Vision (although it is coming via an update at some point) ; Interface isn’t as slick as that of some rivals ; LG’s OLEDs do a better job with standard-def

All of the inherent qualities of OLED combined with the picture processing smarts of Sony equals an utterly stunning television

Sony KD-55A1 review


Sony's first attempt at OLED is a stunning all-rounder

Stunning picture performance ; Clever and unique design ; Really decent TV sound ; Wide viewing angles

Android TV is sluggish and uninspiring ; Design requires a wide TV rack to support it

Sony's 4K OLED debut is a stunning set with a truly outstanding picture and gorgeous design

AVTech Awards 2017/2018


Let's get this out of the way now: Sony's 55in OLED TV is achingly gorgeous, thanks to its ‘One Slate' lean-back design. It's sonically innovative too, eschewing traditional speakers for an enveloping Acoustic Surface technology. And when it comes to...

Test: Sony KD-55A1 (55-Zoll-UHD-TV)


Bereits der erste Blick auf den Sony KD-55A1 im Test offenbart: Hier erwartet uns etwas Besonderes. Und tatsächlich sind Bild- und Soundqualität des 55-Zoll-Fernshers so gut, dass der UHD-TV gleich zweimal einen neuen Bestwert setzen kann. Hinzu kommen...

Sony KD-55A1 (Test)


Veredelt: Die Fernbedienung des Bravia-OLEDs wirkt dank der Rückseite aus Metall hochwertig. Das Tastenfeld könnte jedoch aufgeräumter sein; besonders im Bereich des Cursor-Elements in der Mitte.

Der Sony KD-55A1 tut es seinem größeren Bruder gleich und erklimmt geradewegs unsere Bestenliste. Kein Wunder, schließlich bietet er ein tolles Gesamtpaket aus Smart-TV, hervorragendem Klang sowie sehr guter Bildqualität, wobei die Leuchtkraft in...
