If you really mean 60 Hz full raster refresh, it's twice as fast as a normal TV monitor, and thus can't be fed into one to achieve duplicate displays for large meetings. If you really mean 30 frames per second refresh achieved by 60 Hz half-raster, you should say so in the specs. ---------------------------------------------------------------------- RESPONSE... Don't get mad at me, please. Those are Apple's specs. I don't work for Apple. I could ask them some questions if you would like or you can call them yourself at 800-662-9238. I believe they are also reading the WorkS. Maybe they will pick-up on this and answer your questions. All I can do is report what I saw. The picture on Lisa looked fine to me--nearly the same caliber as the Star--as far as I could tell by looking at. So I don't really care what the refresh rate is, and the dots per inch or number of lines are; that is insignificant to me; results are what count. Also, I did see Lisas piped to several monitors and a large screen display. As I recall, the images on the monitors were as good as Lisa's. In comparison, the quality of the large screen display was not very good: the resolution was definitely lacking, but I could read and see everything. LCDR Larry Byard, USN
