So I'm looking at potentially getting a new TV. Likely a 1080p LED backlit set in the 40"+ range from LG, Sony, Samsung, or Sharp. I know not everyone feels the same way, but I wanted to get a passive 3D set (the active glasses are too heavy and expensive) primarily for gaming as I like the depth its adds to everything (plus the "split screen" mode). I'd also like to find a 120Hz+ set. A real one, not one of those crappy, artificially sped up ones that look like garbage and add a ton of latency. I'm assuming that anything but a TN set is out of the question, but if IPS or VA is an option, I'd obviously prefer that.
Any suggestions? How much do you think I'd be talking with this? I'd like to keep it under a grand, if possible. Any help would be greatly appreciated =)
