Our Score:


LG, it seems, is no longer happy to be thought of as the ‘cheap and cheerful’ TV option. For as well as costing a wallet-frightening £2,800 and delivering a huge 55in screen, the brand’s new 55LX9900 is a set stuffed to bursting point with naked AV ambition.

The extent of the 55LX9900’s ambitions is perfectly exemplified by its design. For starters, it’s the proud owner of what we’re pretty sure is the slenderest bezel yet seen on a large TV. It extends a mere 2cm beyond three edges of the LCD screen – and looks even thinner than that, thanks to the fact that an outer portion of the bezel is actual transparent.

The slender theme extends to the TV’s rear too, which sticks out only a fraction over 30mm. And if all this remarkable lack of bodywork around a 55in screen hasn’t already won your heart, there’s also the TV’s ‘one-layer’ fascia to consider, not to mention the elegant table top stand with its glassy, self-consciously chunky neck and glinting finish.

Arguably the single most remarkable thing about the 55LX9900’s design, though, is the fact that its amazing slimness doesn’t depend on edge LED backlighting technology. In fact, the 55LX9900 employs direct LED backlighting, where the LED lights are positioned behind the screen rather than along its edges. Such TVs are usually thicker than most, but LG has got round this with a proprietary new direct LED design.

The hope has to be, then, that the 55LX9900 will deliver the top picture quality of direct LED technology from an edge LED-like body. Truly a match made in heaven.

The 55LX9900’s connectivity is prodigious. The usual four HDMIs get the ball rolling, one of which can be accessed from the TV’s side. This side HDMI is joined by a pair of multimedia savvy USB ports, while the rear sports a D-Sub PC jack; an RS232 for system integration; an Ethernet port for Freeview HD, DLNA and Internet services; and a port intriguingly labelled ‘wireless’.

To this latter port you can connect LG’s optional wireless AV system, enabling wireless transfer of video – including 1080p HD – and audio from your sources to the TV. We weren’t supplied one of these systems to test, so can’t confirm its quality, and couldn’t get a price for it from LG either. But if you’re interested, it’s really a pity it isn’t included within the TV’s already substantial cost.

Nor is that the end of the extra costs you might be looking at. For disappointingly the 55LX9900 doesn’t carry built-in Wi-Fi support. To take the set online you’ll have to hardwire it to your router or else buy an optional Wi-Fi USB dongle.

Unfortunately, the 55LX9900’s online capabilities don’t currently warrant the trouble and cost of getting the Wi-Fi dongle. For during our tests the only services available were YouTube, AccuWeather, and the Picasa photo site – and neither the YouTube nor Picasa services worked properly.

Thanks Jon for reviewing this TV. Ever since I saw it advertised in the press I’ve been thinking “this is almost perfect”. This is pretty much everything I am looking for.

1) 55” - Noticeably an increase on the 50” I have now.

2) Stunning Design

3) Ultra Slim Bezel – so no space is wasted

There are however a couple of downsides that I need to get over too.

1) I’ve always preferred Plasma technology. Although I appreciate that LCD has got a lot better over the past few years.

2) 3D – I don’t want it and I don’t want to pay for the tech, wireless or the glasses!

So where am I on this..? Very keenly watching is where. I’m going to wait another 9 months and hope that next years range from LG takes this stunning design and technology through into more of the range. Ideally for me producing a 2D version of this TV that looks just as good and for under £2k..

The money isn’t really an issue; it’s just that like many others I hate paying over the odds for something I don’t want and 3D is the expensive elephant in the corner right now.

Thumbs up to LG for this TV and it’s design. Here’s hoping it’s the start of many more TV’s like this next year.

AJ - The TV you are hoping already exists. It's the LG 8900 series - with effectively the same picture and style of the 9900 series, without the 3d option and one or two other features. The 8900 series with the same aesthetic appeal, is receiving excellent reviews all round. So check it out. Looking forward to seeing John Archer review one of these models, preferably the 42 inch version.

I'm torn between the Samsung C8000 series, this LG I have mentioned, the Sony HX803 and forthcoming Philips 9705 model. I don't know why but the Panasonic plasma's just don't do it for me. SD is really important to me too.

Thanks Rod. I'm not as sure as you the the 8 series are as stunning in design as the 9 series though. One of the main things for me is that I want those tiny Bezels and the superb looks that they bring. Looking at the website here are the dimensions of the 2 55" models :-

9900 -- 1255.8 x 749.6 x 31.6

8900 -- 1292.6 x 802.9 x 34.5

The 8900 is also 7Kg heavier !

So I doubt that 8900 has that same stunning visual appeal that the 9900 has.

Certainly worth pointing out and looking at though. Thankyou for the tip.

One last point that justifies my ANTI-3D stance here. The 55" 55LE8900 is £1,600! That's over £1,000 cheaper than it's 3D brother. http://www.electrocentreltd...

@AJ - Something I read on the forums (like you, I am not a fan of 3D) is that the 8900 is THX certified, and came away with a great review.

@Roy Ayling - I have read that the Samsung C8000 series has backlight / black issues. I am keen to see how the Philips reviews and will also be going to the IFA in Berlin this September to check things out there.

@ AJ - You are absolutely right about the fad of 3D TV's that are being sold right now. Prohibitively expensive for the kind of tech that was around decades ago. I think in a couple years time when we get 3D TV's without the need for glasses, is a time when everyone should seriously consider this option. Hopefully by then the use of cables would be unnecessary as well.

@RipSnorter. You are correct about the THX certification on the 8900 and that's very important; I am sure that the picture quality will be excellent. However in order to replace my 3 year old (and still stunning picture) Panasonic Plasma (this is for the mian room) I need this PLUS those stunning looks of the 9900. I know it's vain, and I know I can't have it yet, but next year, hopefully... Or perhaps when they are giving this years models away in 9 months having realised that 3D was a bad idea..? Who knows.

I'm certainly very excitied about LG's new designs and the future models they will bring.

@RazorA. Unfortunately I believe 3D without the glasses is longer than 2 years away. Also I think they will carry on flogging this 3D tech that noone wants for a lot longer too.

just bought this tv and i an completly disappointed. don't buy it. it has so big graininess on sd channels that u can't recognize faces... on hd channels half of the details are missing... 3d and 1080p mkv are not bad = but for tv for 2,500 not good either. I have for compare Samsung ue55c6505 and picture on it is 100x times better. i was sure my lg is broken = but currys megastore was recently open here and i could compare that tv;s side by side in store too. TOP class tv = netcast looks like beta version... u cant setup audio delay on digital output like on every other tv... i just hope i will get my money back... btw: people writing positive reviews on this tv need strong glasses or they just getting well paid by lg.
