Top picture quality: OLED TVs deliver the best results In the search for top picture quality, one still ends up with ?televisions with organic light-emitting diodes (OLED). Their advantages over LCD technology: rich blacks, strong contrasts, wide viewing angles. However, current OLED TVs are also quite expensive - but the quality is almost always right...

Overall, the Sony offers an excellent performance. However, the clearly too high purchase price runs like a red thread through the entire test. Of course, there is a reason for this. 48-inch Ultra HD OLED panels are still quite new on the market, are correspondingly expensive and are probably nowhere near the quantities of 55-inch Ultra HD OLED panels...

The confusing operation spoils the Sony A9's "very good" rating. It deserves this for the picture quality alone: colours, contrast, sharpness and clarity, even in motion, leave nothing to be desired, plus good anti-reflective properties. In terms of sound, the Sony is also among the best of all TVs. In the size class around 1.20 metres, it is an exception.

Finally: First-class OLED picture quality and good sound are now also available in the living-room-friendly 48-inch format. The Sony KD-48A9 is the best TV under 50 inches that we have ever tested.
