Sony KDL-20B4050 review


Sony proves that great things really do come in small packages

Design ; Nice price ; Great sound ; HD picture performance

Some motion blur ; Rather drab onscreen menus

Design might not be to everyone's taste, but HD pictures and audio are very good

Sony KDL-20B4050 television - Pocket-lint


"Never wear brown in town" might be sensible fashion advice for the streets, but Sony has pulled the remarkably similar shade of "mocha" from its locker

Eye-catching design and colour, excellent audio, precise high-def picture

Lacks pizzazz of the bigger Bravia’s, some blur from action sequences

Designed with both style and practicality in mind, the picture quality of Sony’s KDL-20B4050 is nothing special when compared to other Bravias – but when compared to the competition at this size, it’s a mighty tempting telly.

Sony KDL-23B4050 review


An unusual and powerful LCD with a few tricks up its sleeve

Strong picture performance ; Great quality audio ; Some good features

Pricier than many rivals ; Freeview pictures flawed in places

A slightly higher price than the competition, but worth the extra expense for its clean pictures and superb audio

Easy to carry around. Image stabiliser is very good

Appears to have many features that I really don't understand

Sony KDL-20B4050


Excellent sound quality for a smallish TV. Very good picture - great definition

Slides about a bit when one operates the push buttons - could do with a better non-slip base

Sony KDL-20B4050


A truely portable flat screen TV with integrated digital tuner

I only have access to an analogue service at the moment. However the picture quality is nowhere near as good as I get with my larger Sony Bravia TV (KDL-26S2030)

Sony KDL-20B4050


Very easy to set up, FreeView works well even with a conventional ( i.e. non-digital) aerial. Nice sharp picture, though can look a little "processed" with some material. Sound is good for a small flat screen TV

Somewhat magenta or bluish colour cast that gives unnatural skin tones on some programmes. There is no way of adjusting this out without introducing other colour casts
