Phase: Sorry about being a bit tardy with my report on my new LG-37LV3500, with the LED-IPS panel. But, despite it's not having all the buttons, nobs & menu items you and other tweakers relish, I am really pleased with the set.
HD OTA renderings, in general, are superb. ('Course it suffers from the usual knotty problems of constant, inconsistent PQ, varying incessantly, dependent on the input signal. Differing channels, differing sources (live talking heads, commercials, inserted non-hd stuff etc.), differing angles from live coverage producing wholly differing light sources (shadows etc.), differing cameras etc. etc.
However, Sharpness is keen, as is Color. As you may recall, I prefer low-ish saturation levels, looking for skin tones beyond faces, which rather tend towards either heavy make up or sunburn. My tweaking evaluations center around hands, neck, decolletages of people in studio entertainment mode. Or else, unmade-up faces of talking heads or faces of just folks in their natural environment, whether in-or out-doors. When properly adjusted to what we are most familiar with, in my case mostly anglo-saxon hues that trend towards white, with perhaps a little dusting of rose & yellow, these, when well calibrated, produce decent color for everybody(thing) else. After quite a bit of fiddling I pretty much concluded that this unit's color balance is pretty good out of the box, except for "Skin Color", which was reduced to -3. Finally, and perhaps most importantly, it is recommended that one does this either with an exceptionally strong, and clean, OTA signal or, of course, a well made disc with people's faces that remain on screen for sufficient time to try different settings.
On the other hand, "Color" saturation had to be dialled way back from 60 to 26-32. Yes - even with the setup changed from "showroom" to "home" settings.
For daytime viewing I use "Automatic", but nighttime I have to use other settings (minimum, medium), automatic just doesn't seem to work with low (or no) surround room lighting - PQ is quite a bit too dark. (I found this to be also true with my LD550. Why is that?!!!!!
Contrast is set to 100 - a bit high, perhaps - but, no matter what lower levels I tried, the matter of shadow detail is barely improved when going lower; it deteriorates snap & becomes milky. So, while shadow details are only fair to middling, blackness is quite good.
Screen uniformity is not perfect - it seems to fall off just a tad to the right half of the screen - but it's barely noticeable when staring at a totally white screen and I've not found it to be a deal breaker. Nor have I seen any of the dreaded LED light leaks on black screens.
So, all in all, I've lucked out with this LED-IPS panel and I am another satisfied LG customer. But I do wish they would stop playing the IPS rouette. It's a really black mark against the company and makes for consumer frustration & disappointment. That said, please accept my thanks (again), Phase, for I.D.-ing this matter to all of us so many moons ago, and which, in the end, allowed me to seach for and buy my new toy. Thomas.
P.s. Talking to a tech support gent at L.G. the other day I was told - off the record - that LG is planning to put IPS panels in all their panels. Whether that this referred to the LV series only or all other also I did not ascertain. FWIW. T.
