Nearly any modern Windows laptop should be able to "dual head" (the LCD and the display panel/projector, as "adjacent" screens). > The original question was about showing different things on each > monitor: the console visible to the speaker, and graphics visible to > the audience.

PC laptops definitely can, even under XFree86/Linux. (i.e. have the left portion of the "display" be on the LCD, the right portion on the external video-out (connected to a projector/display panel). It is easier to do this on Mac, of course. (it's useful for having notes on the LCD, while the presentation is on the projector, for example). For desktops, you can use 2 video cards (in which case one would usually be a PCI-based, and the other AGP, so the quality may be unequal), but many of the intermediate/expensive video cards ($90US and up, i.e. Radeon 9000) have dual outputs; for about $130 and up, you can actually find dual digitial outputs, which are very nice if you've got digital capable LCD monitors. (or want to do stereoscopic displays, which is why I care...). best, -tony -- A.J.
