LG 42LM670T - 2D Performance and Conclusion

LG 42LM670T


Our Score:


With 3D only likely to occupy a fraction of most TV users’ time, though, it’s handy to discover that the LG 42LM760T is also a first rate 2D performer. For instance, it’s easier to appreciate in 2D mode just how sharp and detailed its HD pictures look - a quality, moreover, that’s delivered without pictures looking noisy or excessively gritty (which they did a little on last year’s equivalent LG model).

The 42LM670T’s contrast performance impresses greatly too in 2D mode. We’re used to LG TVs delivering plenty of punch and vibrancy at the bright end of the spectrum, but the depth of the TV's black level response is excellent too. So long as you keep the backlight under control, black really does look black.

Reasonably even backlighting

What’s more, although dark scenes aren’t completely devoid of backlight inconsistencies, what inconsistencies there are tend to be so small and - with a sensible backlight setting - so faint that we don’t consider them much of an issue at all.

The colour vibrancy noted with 3D is abundantly obvious in 2D too - only with 2D you get a better appreciation for the LG 42LM670T’s ability to render subtle blends with good levels of finesse.

LG 42LM670T

For all its charms, the 42LM670T isn’t a perfect TV. Moving objects lose a little resolution if they pass swiftly across the screen; some shadow detailing goes AWOL during dark scenes once you’ve optimised the backlight and brightness settings to give the best black colour; and you have to avoid the set’s out of the box Vivid preset if you don’t want colours to tip over into cartoonish lunacy.

Audio is a little run of the mill too - a predictable result of the set’s dazzlingly slender body, we guess.

Input lag ahoy

One final irritation finds the TV running with a measured input lag of around 100ms. This is way higher than the figures posted by most rival brands, and could prove high enough to damage your performance if you’re into playing time-sensitive games like Call of Duty or Guitar Hero.

If you’re not a heavy gamer, though, none of the other niggles we mentioned are worth getting disheartened about. For the simple fact of the matter is that the LG 42LM670T’s good points far outweigh its bad ones, making it a truly outstanding mid-range effort.


LG has arguably been the ‘most improved’ TV brand for the past couple of years. So it’s not actually a great surprise to find that, on the evidence of first the 55LM660T and now the 42LM670T, 2012 appears to be the year where LG has well and truly caught up with the best of the TV Joneses.

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???
