I wasnt sure which forum to put this in, but I thought more people would know the answer here. Apologies for my lack of knowledge, but I was wondering about the refresh rates of plasmas and projectors. I know that larger screen CRTs and rear projections can be bought in 50hz and 100hz flavours, the argument being that as the screen size goes up, the amount of flicker becomes more noticeable (although this is a matter of some debate). I notice that Ive never seen Plasmas or Projectors advertised as 100hz, even though they potentially have much larger viewing areas. Is this because they display the image in a different way and so the flicker can not be seen? Or are the refresh rates variable?
