I just bought and returned a 39LN5300, which was a 2013 LG model with AMVA. I could not stand the gamma shift and sitting at around three feet away (as a PC monitor), I could see the shift and the loss of contrast and brightened colors taking up the left and right quarter screens to the edge, basically half the image. Another killer was I like to stand up and stretch every hour and use the PC while standing up, staring down at the TV. At this angle, a ton of detail is lost and its basically a TN panel. Another problem is the coating on the screen, which I could see my reflection very easily on dark images. I am currently using an old 32" Panasonic with IPS that doesn't have the deepest blacks or contrast, but is light years ahead of the LG in everything else.
I got excited when I saw the 40" W600, it's relatively cheap cost, and the fact that it was Sony, which I've heard nothing but good things about. But I am hearing that it has an SPVA panel by Samsung? Or maybe the same sort of AMVA tech by AUO that was in the LG I returned? People in the LG thread also said that model had an amazing screen as well and IPS-like viewing angles. I beg to differ. Many are saying the same thing for the 40" W600. How different is the 40" W600 in comparison to the 39LN5300? Ideally I would want an IPS screen, but it's hard to find or figure out which TVs in the 32-40" range have them, since they all seem to be some type of VA or another. If the VA tech in the 40" W600 is significantly different and/or better than the 39LN5300, that is what I am hoping for, since I do like the balck levels and contrast of the tech, but so far my only experience with it has been really bad viewing angles.
