I suspect the slow drawing rate is due to the drawing being done by the anemic, shared "display controller" (3274?) IBM used for 3278/3279/3290 style displays, rather than any inherent slowness of plasma displays. The CRT-based "big screen" (43 x 80 character!) 3278s took a noticeable interval to redraw, too. It occurs to me that plasma screens might have an *advantage* in performance. Plasma-panel pixels have "memory": once set or reset, they stay on or off, and don't need refreshing. This means they don't eat memory bandwidth like CRT displays do. -- Rich McAllister (rfm@sun.com)
