Sony KDL-55 X 4500


The Sony KDL-55 X 4500 TV is a 55-inch, Full HD, LCD TV. Available since autumn 2008, the model now lists at 3,300 GBP. Online pricing begins at around 3,100 GBP.

Hybrid digital tuner (DVB-T/-C) ; Huge contrast ratio ; Relatively low power consumption ; Accurate colours ; Crisp motion

Pronounced dependence on viewing angle ; Blurry 576i/p video via HDMI

At the time of testing, this TV was as good as LCDs got. With enormous contrast, the KDL-55 X 4500 does away with the technology’s — until now — biggest flaw. But it’s not all rosy: To reach true perfection, the TV would need to process standard...

Sony KDL-46 X 4500


The Sony KDL-46 X 4500 TV is a Full HD, 46-inch LCD TV, on the market since autumn 2008. Sony lists the TV for 2,300 GBP, but it's available online for about 1,800 GBP.

Excellent colour matching ; Contrast-rich and bright images ; Accurate 24p picture (even with films arriving as 60i/p) ; Excellent sound ; Energy efficient

Picture depends strongly on viewing angle ; Blurry picture via 576i/p

Sony’s local dimming technology impresses all round: The KDL-46 X 4500 produces an artefact-free image with rich contrast and superb colours, despite its low power consumption. The only thing spoiling the fun is the relatively strong viewing-angle...

Sony Bravia KDL-46X4500


The 46-inch, 1080p, LED-backlit Bravia KDL-46X4500 LCD TV produces, on occasions, the best pictures we've seen on a flat TV from Sony. It's also attractive, well-connected and far cheaper than sets that use the same technology, although it'll still...

Capable of excellent picture quality ; well-connected ; fairly attractive ; far cheaper than other LED-backlit TVs with RGB dimming

Very expensive compared to Samsung&apos ; s latest LED sets ; needs careful calibration ; uses last year&apos ; s Bravia Engine 2 video-processing system ; colours occasionally look slightly unnatural

Sony has aimed high with the Bravia KDL-46X4500, its debut LED-backlit LCD TV. In many ways, its efforts have paid off handsomely, and the TV is certainly capable of producing some stunning pictures. It's not quite perfect, however, and that's enough...

Very expensive compared to Samsung's latest LED sets ; Needs careful calibration ; Uses last year's Bravia Engine 2 video-processing system ; Colours occasionally look slightly unnatural

Conclusion If considered in isolation, Sony's Bravia KDL-46X4500 is an excellent, sometimes imperious, TV, suggesting again that LED backlighting really is the quality option for LCD technology. It's just a pity for Sony that Samsung's current LED sets...

Sony Bravia KDL-46X4500 46in LCD TV


Sony's decision to use LED backlighting is paying off as we look at the KDL-46X4500 LCD TV.

The 46X4500 confirms in no uncertain terms that the jaw-dropping pictorial glories of the 55X4500 were no fluke. Sony really has hit the ground not just running but sprinting with its debut LED sets, delivering HD pictures so good that they actually...

Review: Sony Bravia KDL-46X4500


This Sony Bravia is in the forefront for black inkiness and picture quality among LCDs but is priced primarily for the well-heeled.

Overall sharp and clean pictures; plasma-like blacks; tight bass and crisp treble; onboard JPEG/MP3 playback via USB and network; four 1080p24-ready HDMIs; RF-based remote control; unique and customizable design

Extremely pricey; no remote backlighting; no DivX playback; chassis a bit on the thick side

This Sony flagship Bravia LCD TV is simply brilliant in most areas, particularly in deep blacks, but is slapped with sky-high pricing and outgunned in this aspect by the Samsung Series 9.
