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

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

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...

“Doen, als geld het probleem niet is.”


Heb de tv nu ca. 5 maanden in mijn bezit en (nog) steeds is iedere dag weer een gewaarwording van "Oh, wat een prachtig beeld". Tv levert een goede geluidskwaliteit. Echter heb mijn oude Onkyo-receiver (7 jaar oud) vervangen door de Yamaha RX A-1070...

Schitterende beeldkwaliteit ; Prachtige kleuren en ongekend contrast
