I bought my first large LED and it had to be this because of the picture quality , its nice, crisp and colours really seems too be popping out when u watch the animated movies on this. I love the features it has like the crystal clear voice for the sound effects and changing the white colour tone and skin colour tone in the picture settings.
Moreover if u dont know how to use it they also have a demo in the settings and u can watch it to learn the functions. I am very impressed with the quality and usb supports various media formats like avi, mkv, mp4, etc and yes u can update the firmware on maximum models of LG tvs. Happy with the purchase.
