Probably the same with xrandr, you need to set both screens to the same
resolution and then you'll see the same desktop, no scrolling. I don't think
that I ran into any system that knows how to do it otherwise.

As for projectors, if you need more that 1024x768 people probably won't be able
to see it on screen. I also haven't seen any standard projectors go above this
resolution yet.
