Thank you > Windows needs to know what you want to do with the second monitor: do you want it to be an extension of the first, giving you more desktop, or do you want it to be a copy, e.g. to run a projector while you still work from the laptop screen. It also wants to know whether you want a taskbar on one monitor or both, and which is the primary screen. So what you're seeing on Windows is the default setting: you should find that if you move the mouse pointer off the edge of the main screen, it appears on the projector screen, though you'll have to experiment to find which edge to move from. You need to right-click on an empty area of the desktop and I'm not sure where you go from there, but explore the menu until you find the multiple monitors setup. I'd guess that Macs would have similar features, that's probably where MS copied theirs from, and almost certainly where the Linux randr multiple monitor setup came from as well. -- Joe
