Don't we all. Unfortunately, the current chipset can't deliver that many colors at the resolution you specify. 16 colors at 640x400 max, unless you want to start playing with copper lists, as others on the net have mentioned. But I don't think that is a good solution for a highly dynamic environmnet such as the Workbench, where windows and images are constantly being moved about. Anyway, the current Workbench is limited to 4 colors (two bitplanes) because any more bit planes would start stealing bus time from the CPU for the display memory access, resulting in a loss of performance. 2) Ideally, this would also be the standard resolution for actual drawing programs as well. This would prevent that annoying switching effect one notices on ibm at's and their clones. Well, the Amiga offers multiple display resolutions, but it doesn't suffer from that "annoying switching effect" you describe. It comes from having non brain-dead video hardware, and software which was designed to allow different video modes to coexist on the same display. 3) Please note that I am willing to spend up to $1200 (cdn) for a well defined and integrated set of display equipment. And I'm sure some of the people in this newsgroup would be willing to spend more. But sadly, we have to wait. --M -- Michael Portuesi Silicon Graphics Computer Systems, Inc. portuesi@SGI.COM
