Two key factors to any LCD TV. First is the viewing angle. Most all have excellent viewing angles compared to a decade ago. Simply walk to the left or right until the picture degrades. That is the viewing angle.

Second is persistence. Often stores will display their 'test' programs by using slowly moving items. Persistence means a world fast sprinter running across the field as a halfback instead looks more like the Flash (from comic books).

A higher refresh rate means the TV can better follow the world class sprinter. However view it yourself to learn if your eyes and brain work too fast for that screen.
what does 'edge lit LED' mean?
