I bought a 120Hz, 46" Sharp over a year ago, and ended up taking it back a few days later as the lag sucked. Instead, I got a 480Hz 55" Vizio, and it's awesome. They give this BS about no lag, but, at 120hz and a 90" screen, there is no way an object, such as a ball moving close to 90" inches in a second or so isn't go to show significant lag and artifacts.
Sharp should pay more attention to quality, and be less concerned with trying to grab headlines with sensational tactics.
This is a Sharp TV and has nothing to do with LG--please pay attention when you write an article.
