Sony Bravia KDL-46Z4500 46in LCD TV


Our Score:


And so to 200Hz., and the discovery that it's good, but not the absolute picture quality tour de force we might have been praying for. In other words, while it does make motion in pictures look smoother and - usually - clearer than you'd get from even a 100Hz LCD TV, the leap forward isn't anything like as profound as the leap from 50Hz to 100Hz.

That sounded a little harsher than I intended it to. Obviously any improvement in picture quality, no matter how minor, deserves credit. I just think it's important to cut away a little of the hype surrounding the 200Hz feature; to say that the difference it makes is marginal rather than revolutionary.

In fact, I'd argue that Philips' HD Natural Motion system, which has been around for the best part of a year now, actually makes motion look even smoother and clearer than Sony's 200Hz engine.

Having said that, Sony's new motion processing does score points of its own over the Philips engine for the way it generates practically no nasty side effects whatsoever. With the Philips HD Natural Motion TVs you're forever tweaking various settings with different types of source material, in order to ensure you're not left looking at too many nasty image processing artifacts. But with the 46Z4500 you can enjoy the 200Hz benefits glitch-free with pretty much anything, so long as you don't often set the Motionflow system higher than its Standard level.

Just occasionally something particularly tricky, such as a facial close-up moving across the screen, can seem to smear a little bit, either because of problems with the speed of the Sony's processing or because the processing can't quite figure out the best thing to put in the three extra frames it's calculating. But these instances are rare, and easy to live with in the context of all the good the 200Hz engine is doing.

And anyway, the 200Hz system is far from the end of the 46Z4500's talents. Its colours, for instance, are superb, portraying with exceptional vibrancy the riot of colour on show during the Captain Jack hanging sequence towards the end of the first Pirates of the Caribbean film.

Using the Wide colour mode actually makes these shots look almost scarily aggressive and eye-catching. But it seemed to me that the tonal accuracy suffered a little in this mode, so I personally preferred the Standard setting.

Well having stood in a Sony showroom last week for a good 15 minutes being unable to tell the difference between 2 46" TVs, one with and one without 100hz processing, forgive me if I don't get too excited about 200hz. Just another way of extracting another few hundred quid for the same telly if you ask me.

Does somebody need to tell Sony were currently in a credit crunch.. :) Yeah Yeah, some people with more money than sense will end up buying them I suppose.

@basicasic To be fair Sony showrooms don`t seem to be the best of places to `audition` a TV in my experience. I recently popped into the Sonycentre, Cheltenham for a butchers at the latest tech & was totally underwhelmed by it all - from the POV of picture quality my 4 year old 720p 32" Sony LCD looked better than everything they had on display! (Yes, before anyone asks, I did stand further back from the 46 inchers :))

There is a lot to be said for properly setting up a TV & they never seem to be even close at retail outlets. I am sure some of the highbrow HiFi/AV stores will be better - but I'm not paying through the nose for a TV I can get 30%+ cheaper online, nor will I pay for someone to set it up; hence why I rely on online reviews for all my AV gear. (Caveat - if I win the lottery - strike that I don`t do the lottery. If Ernie gives me a wad of cash then I may change my mind & go for a custom install :). Tho knowing my luck it would only be enough to `do the kitchen` & the missus will overrule me).

Yeah, I'd echo Matt's views. Most LCD TVs actually have a "showroom" mode that bumps up the brightness to "make it look better". This might work on the lowest common dominator, but it rarely means seeing the the TV at its best.

Just wonder why this have got TRrecommend? As u've mentioned

- it worse than almost any LED enhanced tv;

- even with "200Hz" it worse than 100 Hz Philips;

- very noisy;

- black levels are also below or around average;

the price? It's too much for such bad tv (see above). For the name 'SONY' ?

Is it possible for TR to hire a reviewer with less lofty standards that allow them to review and appreciate affordable televisions/gadgets.

I understand the whole appeal of enjoying the specs of a dream gadget.."window shopping"..but it would be nice to get expert reviews on devices that cost less than half a month's pay.

Just my two pence, thanks.

Peace & Love

@bazza - here is a list of all the TVs we have reviewed since January 2007, sorted by Most Affordable first :)

A lot of these tv's, along with other new tech, come down in price by about 50% within 6-12 months of being released. So I think its useful to read reviews of today's top end stuff, on the basis that it could be affordable to the man on the street in 6 months. For example, I was very taken with the Toshiba 40zf355d when that first appeared in May this year, but it cost something like ٟ,500, which I couldn't justify spending for a tv. I have been watching the price ever since, and now its going online for about 𧿘, which is much more like it!

The clouding issue with previous sony lcd 46w4500 . I have one and yes it happens but only when there is no picture on and it may bother some but the picture quality is amazing compared to my last lcd .Great tv

you know i have tested this Tv and i dont see a big diffrens, between 100hz and 200hz

What i find most interesting about this particular LCD tv and others of course, is that what ever 'independent' review one reads, they all tend to come out with varying degrees of conclusion! This set for example is resonably well reviewed by TR, however one only has to cop a sneaky read ( or indeed actually purchase!) a copy 'Home Cimema'or similar to very often find a considerable different conclusion to the same set,thus leaving the likes of myself in a quandry, as to whether to put this set on my seriously consider list of forget about it!I realise one could wait forever in an attempt to find the 'perfect' set and it still not arrive, but when one is considering spending ٟ,500+, this is pretty serious money to most people and i for one don't wish to end up with a pup! TR are you in a position to be able to offer any explanation as to why different reviews occur for the same set? Is it anything to do with differing testing equipment/environment for different testing centres?

I bought one of these tvs on the strength of some good reviews, but although the picture quality is generally excellent, and motionflow works well, I am v disppointed by the amount of light shining onto the screen from the rear. There are pools of light clearly visible around the edges of the screen. For this amount of money I would have hoped for something better.
