Haven't you ever heard of vector graphics displays? It is quite possible to have a display system based on something other than pixels. The Evans and Sutherland PS-300 is a good example - the display is vector-based, meaning if a given area of the screen doesn't have anything drawn on it, the gun never passes over it. If you have fewer objects on the screen, it is easier to refresh each one more often; the more objects you have on the screen, the longer the minimum time between refresh cycles. Vector graphics have a lot of advantages over raster graphics, but unfortunately the technology isn't quite as advanced. I believe that as display resolution goes up, the likelihood of seeing vector displays again will also go up. Who wants to store a 8000x8000x24 bitmap anyway? Have you got 200 Meg to spare?
