from the AVS forum on this particular set:
"- Does this TV have 120Hz processing? Is it like the LCD's I see in the store? Why does it say 60Hz when I press the info button?
Yes, this TV is ALWAYS doing 120Hz video processing. It cannot be turned on or off. This is not the same effect that you may see on some LCD's in a store. Those LCD's have a feature called something like Motion Enhancement that is software to enhance the motion of the image. This often has the effect of making film look like video, and can also cause what is known as TBE or triple ball effect, where you might see three balls on a fast moving baseball due to software frame interpolation. Since DLP's have a hugely faster update rate, this is not needed. The 120Hz on this TV is used to provide judder free display of 24fps sources, such as blue ray movies. When you press the info button on the remote, it shows the frame rate of the SOURCE material. For regular TV, this will usually be 60Hz. For Blu rays, it will be 24Hz. But the TV always does 120Hz video processing. 120Hz is also used for the 3d features of the TV, or to provide two full screen independent images at 60Hz to users. These features require special glasses and must be supported by the source material"
