LG makes some great TVs, but you really have to watch out with them, because they will periodically slip some very questionable designs into their lineup (like the 120 Hz HDTVs that didn't allow consumers to disable the motion interpolation). When they introduced their first "240 Hz" HDTVs a couple of years ago, it was nothing more than a 120 Hz design with a backlight strobing at 240 Hz. Not only was this not true 240 Hz, and nothing more than a gimmick to tout on a spec sheet, the strobing backlight had the net effect of cutting the light output in half.

Sony and Samsung did the 240 Hz implementation correctly, by using two separate 120 Hz video processing chips and alternating them. LG, Toshiba, and Vizio did the fake 240 Hz.

With this kind of history and a low price point, I'd be very wary of buying into something that might do nothing more than pump up a spec sheet. This very well might be a good TV (LG's inclusion of ISF calibration settings is something that only Pioneer used to offer), but I wouldn't put any stock whatsoever into this "480 Hz" number.

Judder reduction is fully accomplished using 5:5 frame repeating at 120 Hz, and the motion interpolation feature at higher refresh rates simply means more interpolated images -- and that's not a good thing.
