Carla Rowland wants to know how important the refresh rate is when shopping for an HDTV
A 120 or 240hz refresh rate can certainly improve the look of an LCD HDTV, especially when dealing with fast-moving content like sports or action movies. But the difference may not be all that significant.
It's worth remembering that there's no such thing as 120hz or 240hz content--just 24hz and 60hz, because film is shot at 24 frames per second (fps) and video at 60. One key advantage of that faster refresh rate is that it can show both types of content at their native speed, since both 24 and 60 divide evenly into 120 and 240. This results in better-looking film-originated content, although the difference is only occasionally noticeable.
