Hi I have been using a dual monitor configuration for a number of years, and could never go back to working with one monitor, as the benefits of having the extra desktop space are enormous and beats the other choice of buying a bigger and bigger screen. Before Microsoft offered dual monitor configurations I worked for a company that used dual monitor cards, but we always had trouble with the drivers, had incompatibilities with software, and had to put up with silly things like the start bar being spread across both screens or when maximizing a screen it maximizes over both screens, or something using full screen mode does the same thing – all things that disappeared by using 2 cards and letting windows take care of the rest. You need to use pci (or agp cards), that has a windows driver, and at least one card must be supported by Microsoft to be used as a second card (although does not require a special driver.), which is most, at least with a known chip. I use an ATI All in Wonder pro AGP as my primary card, with an old ATI mach 64 as the second (although have also used a S3/Virge). This configuration works no problem on win98. On win2k it is odd, because if the agp is configured as primary card in the bios, the mach 64 driver cannot start, so in the bios I reverse the settings, and that does the trick. The pc boots with the mach 64 being the primary display, but then in win2k you can select which functions as the primary display, and I choose the All in Wonder. In theory you can use as many cards / monitors as you have pci slots available, and configure them positioned to the left, right, top or bottom of each other, and each with a different size and resolution setting, but I imagine for practical reasons 3 would be a max. Once you have set up your system with 2 cards and seen the benefits: - when programming having visual studio in one screen, with msdn or other reference material in the other. - When debugging having your program running in one with watching debug output in the other, or spreading variable lists, stack lists etc over both screens, or changing the resolution of the second screen to see how your program looks at different resolutions… - when surfing the web, having 2 browsers fully visible and while one is loading, you can be reading the other. Etc. etc. etc. I’m sure you will not want to use a one monitor system again. Leo
