I'm not sure about LG as a brand, but a solid 5 eggs on 100+ reviews can't be wrong, good warranty and specs. What I like about the big 3 are their quality. I'm a graphic designer by trade and those three brands offer excellent quality in color and especially construction, generally offer better warranty as well. I'm generally pretty an*l about monitors as in my profession, what appears on screen needs to be as close to what the the producted is going to end up looking like.
I've seen the one's as Best Buy and have noted poor color response and unimpressive contrast ratios (even though they were rated high). I also look at the base/casing of the monitor. If it appears weak/cheap, what makes me think they're going to put good components inside that?
However, what may be unacceptable to me, may work just fine for someone without as high as standards as me. So, I stress it's just my opinion.
My impression from that LG is that it is pretty good. I try and stay away from sub $280* 22"ers.
* Note this is Newegg prices. Expect to pay $50-100 for Best Buy 'crap'.
