I have been wondering for a while what reason there is for LCD displays to have refresh rates at all. There is nothing to refresh per se. Shouldn't the display just tell the videocard it can handle frames as long as they're at least some ms apart, then the videocard pushes the frames when they are ready, whenever that may be? It makes way more sense to me than carrying over the limitations of old (CRT) technology.
