So maybe you can just turn the LED Local Dimming off? Actually no. For if you do that the LG 55LM760T's black level response takes a heavy hit, leaving dark scenes looking disappointingly greyed over.
There are other problems with the LG 55LM760T’s dark scene handling, too. First there were numerous areas around the edge of our test sample's screens where you could clearly see light 'leakage' sneaking into very dark scenes. Dark scenes also tend to exhibit slight illumination level and tone differences when they should appear with more or less uniform black colours.
What’s more, even with local dimming active and the backlight setting knocked down to around 50%, the LG 55LM760T's black level response isn't all that profound. Certainly when compared with the efforts of the game-changing Sony KDL-40HX853 and subsequent HX853 series this year.
The set's apparent struggle to deliver a convincing black colour also results in a shortage of shadow detail in dark corners of the picture.
Overall, it's impossible to shake the impression while watching dark material on the LG 55LM760T that maybe LG's quest for a slimmer bezel has resulted in a few picture quality compromises.
The LG 55LM760T further suffers with a more familiar LG problem: input lag. We measured a 68ms delay between pictures arriving into the TV and them finally appearing onscreen which, while actually not as high as some previous LG TVs, is still potentially enough to negatively impact your gaming performance with some types of game.
LG 55LM760T 3D
Allowing us to finish on a more upbeat tone, thankfully, is the LG 55LM760T's 3D performance. You seldom see any of the crosstalk ghosting noise so rife with active 3D screens. There's none of active 3D’s flickering issues at all, even if you're watching in a bright room. Depth reproduction is profound but natural. There's far less brightness and colour vibrancy loss with the set's passive glasses on than you get with active glasses. And perhaps best of all, you can watch the 55LM760T's 3D images for much longer than most active ones without feeling fatigued.
Even the set's black level problems are less obvious in 3D than 2D, thanks to the (slight) brightness reduction induced by donning the 3D glasses.
This isn’t to say that 3D looks perfect, mind you. First, as usual with very large passive 3D TVs, you can certainly routinely see evidence of the horizontal filter lines that lie across the front of the screen. Also, curved edges and small objects tend to look a bit jagged, and even if you use the set's Smooth motion processing option, horizontal pans can - as they do with many 3D TVs - look a bit jerky. Still, overall the LG 55LM760T presents an extremely family friendly and relaxing 3D experience.
It also delivers a reasonably decent audio effort considering how skinny its bodywork is too. The only bulge on the TV’s rear comes at the bottom, where LG has sensibly sacrificed a little thinness to incorporate some reasonably robust speakers. There’s still no real sense of bass to be heard, but soundmixes at least sound decently detailed and reasonably rounded with their mid ranges.
LG 55LM760T Verdict
For much of the time the LG 55LM760T is a dazzling TV, with its extraordinary designer looks, joyfully aggressive approach to pictures, outstandingly flexible multimedia playback and content-rich, beautifully presented online services.
These strengths will be enough in themselves, no doubt, to win the set many friends and fans among relatively casual users. Which is why we've awarded the set an overall score of 8.
However, we haven't felt able to add a Trusted Reviews Recommends badge to that 8 score. For as well as serious gamers potentially finding it hard to live with the TV's rather high input lag, serious film fans will likely struggle during dark scenes to see past the set's numerous backlight flaws.
Finally, despite the fact in some ways its £1,499 price doesn’t look bad for such a gorgeously designed and feature laden TV, there’s no doubt that the similarly priced Sony 55HX853 is a superior all-round picture performer.
