I took delivery of the LG 47LM7600 today. It's a local dimming, 240hz LED LCD design that's a couple of steps up from the LG 42LM5800 that it replaces. It has all 7 manually selectable 3D modes that Frank described earlier, and 3 more than the 5800. I watched about 4 hours of 3D on it tonight. Here's the short-form report:
The set is not calibrated, of course. I did my viewing in the "Game" picture mode. I found it the most satisfying, although I almost didn't try it because I've hated game mode on every other display I've seen. ISF 1 & 2 were far too red and flat for my tastes. Game, at its defaults, was probably too blue, but overall it created a level of contrast and "pop" that I loved. I saw things in Avatar I never noticed before, and the sense of depth was striking. Skin tones looked pretty good to me. That impression might change, though, as I watch more content.
The dark lines and aliasing in 3D mode are noticeable, but more so because the screen is larger. I'm succeeding a bit in training my eyes not to go immediately to parts of the screen where I know I'll find such artifacts. That's impossible with certain content, but psychologically I'm adapting pretty quickly. It reminds me a bit of how I adapted to the rainbow effect with my DLP projectors. After a couple of days, I found it difficult to see them, because my brain/eyes "filtered" them out very effectively. If I was away from DLP for a few days, I could see them again and had to readjust.
Ghosting is not perfect, but it's extremely good. It's better than any display I've ever owned (8 of them), and not too far behind a couple of 100% ghost free DLP projectors I've seen. The ghosting "sweet spot" is greater on the vertical, probably just because it's 5" bigger. Outside the vertical sweet spot, it ghosts plenty, but it's easier for me to stay in the sweet spot than it was with the 42" 5800. Left to right angles didn't affect ghosting much, but of course the 3D effect changed and became less immersive, as it does with all displays.
It's the brightest 3D I've ever experienced.
Because of these two things (ghosting and brightness), the sense of 3D depth is the best I've seen, period. It's stunning how much difference those two factors together make. Avatar, Deep Sea, Grand Canyon Adventure, and 3 or 4 other titles took on a 3-dimensionality that was intoxicating.
Black level and contrast are better than the 5800 (probably because of the local dimming), also adding to the sense of depth. Contrast overall is not as good as my Epson 3D projector, and not even close to the JVC RS40/45 projectors. But since the JVCs ghost so horribly, the LG passive display beats them silly for 3D. Overall performance here is not bad for LCD, but it also doesn't touch plasma. I think watching episodes of Fringe on Blu-ray would be much less satisfying on this set than my Samsung plasma.
One thing I was most fearful of was that the display would be uncomfortably big for video editing. I haven't done a marathon edit session yet, but it doesn't look like it will be a problem. It barely fits into my existing space, but I didn't have to change anything, so I consider myself lucky in that regard.
I'll be recommending these LG sets to any friends and relatives who might be interested in 3D. I honestly don't think most would be as bothered by the jaggies as I am, and even I am adjusting nicely to them. For 2D, most people are also not nearly as concerned about black level and contrast as I am. I doubt these things would bother 99% of the people I know about this LG set.
Finally, the passive glasses I got with this set are wonderful. Super light, super bright, and they cause no eye fatigue whatsoever. They also seem very uniform across the lenses in terms of performance (except for the obvious line pattern created by the FPR). I can't say that about any of the active glasses I've owned - JVC, Epson (although they're by far my favorite active glasses), Samsung (two types), 3D Heaven, Xpand, Sony. Although it may not be obvious while watching movies, I've picked up on distortions created by looking through different parts of the active lenses. This has nothing to do with the flashing shutters, either, which can cause fatigue after prolonged viewing. I probably suffer less than most people from such fatigue, but the improvement with passive glasses is obvious even to me.
What about 4k passive OLED? I might just ditch all my current stuff to buy in, because it sounds like it has the potential to solve all of the above problems. Meanwhile, I'll enjoy this LG. I might end up re-watching most of my 3D library on it, even though my computer room isn't the most comfortable place to watch movies.
Thanks again, Frank. I'm sold.
