Despite being an ‘LM670T’ rather than a ‘LM660T’ like the recently reviewed LG 55LM660T, it turns out that the LG 42LM670T only differs from its lower-numbered sibling aesthetically. So despite its remarkably glamorous looks, it’s still not one but two rungs below the very top tier of LG’s new range (which will be crowned by the soon-to-be-reviewed LM960V). This means it doesn’t get the dual-core processors and high-spec motion handling technology sported by the higher models.

However, it still boasts LG’s MCI 400 motion control, as well as edge LED lighting with a degree of local dimming and, of course, LG’s passive 3D technology. LG continues to rub its active 3D rival’s nose in it, moreover, by shipping no less than five pairs of glasses free with the TV. The active 3D Panasonic P50ST50, by comparison, ships with not a single pair of 3D glasses.

Magic remote

One last point to mention about the 42LM670T before unleashing it on a few of our favourite TV and movie sources is the fact that in keeping with recent TVs from Samsung and Panasonic, it ships with two remote controls: one standard one, and a ‘Magic’ one you can point directly at the options you want onscreen. This intuitive approach has been greatly improved from the slightly cumbersome version introduced last year, and the addition of a ‘wheel’ knob for spinning quickly up and down menus has made it a genuinely compelling alternative to the normal remote control experience.

LG 42LM670T

LG doesn’t claim to have substantially tweaked its 3D technology from last year’s iteration. Yet surprisingly, it seems to our eyes to be quite a bit better. Whether it was the lantern sequence in Tangled, the final showdown with Colonel Quaritch in Avatar, the mermaid sequence in Pirates of the Caribbean 3 or the Golden Gate Bridge sequence in Monsters Vs Aliens, the 42LM660T’s 3D images never looked anything less than excellent.

3D delights

Colours are consistently vivid, for starters, and the drop off in brightness between 2D and 3D fare is marginal - certainly miles less than you get with an active 3D set. The lack of any shuttering mechanisms in the 3D glasses means the LG 42LM670T’s 3D images don’t suffer any flickering either, and the image only very occasionally betrays any crosstalk double ghosting noise.

Certainly there are precious few active 3D TVs that can deliver such crosstalk-free 3D experiences - though as ever, we do need to qualify this by saying that passive 3D TVs suddenly go crosstalk crazy if you watch from a vertical angle of more than 13 degrees above or below the screen.

LG 42LM670T

Intriguingly we also felt as if the 42LM670T’s passive 3D images looked more detailed and ‘HD’ than they did on last year’s equivalent LG sets. Since LG doesn’t claim to have adjusted the passive filter across the screen or its glasses in any significant way, we can only presume that this apparent improvement is caused by the superior quality of the panel and processing behind the 3D filter.

If you look really closely you can see traces of horizontal line structure around bright contoured edges, and there’s a slightly less dense look to images than you get with a good active 3D image. But overall we have little doubt that many people will be utterly seduced by the LG 42LM760T’s 3D experience.

I like their choice of color on the frame. I was starting to get sick of the dull black frames that are placed on every single TV in the market.

I love this TV for its beautiful design and the metallic silver stand. Nothing else in the market right now looks better than this.

Nice stand and impressive picture quality.

wow I agree with the review. The only flaw it has is it's size! Haha we want bigger!

I love its design. I like TVs that have a very thin frame and this TV kinda looks like a wall picture in this review.

The Smart interface is awesome with easy access to premium apps. I believe that the magic motion remote is another method that benefits the Smart interface. I love the BBC Iplayer that provides me with all the great sports game to watch. Everything can be transferred 3d even playlist from youtube. The metallic silver stand makes it look awesome as furniture. I wish there was a bigger size but that is why the LM760T is here for.

I cant decide between this TV which i can get for £699, or a Samsung UE40ES6900 which I can get for £849 inc keyboard and soundbar.

I have read bad reviews about this LG ghosting and lag, and I cant seem to find any reviews for the Samsung.

Any help appreciated

Get your bloody models right, you refer to this tv as the 760 at least twice rather than the 670..... So which is it???
