All "data shows" I have seen use the monitor port directly, so the monitor is blacked out. Is it possible to have a set up where I can see both on the monitor and the audience the projection? From the answer to this Q, it seems that would work well with R.
Most reasonably new laptops allow the display to show in both places. (There may be limitations on the resolution to accommodate this.) The original question was about showing different things on each monitor: the console visible to the speaker, and graphics visible to the audience. I don't know of any PC laptops that do this, but I think some Macs can. At least that was my interpretation of a minor flap before a presentation at UWO where the projector showed the desktop and the laptop screen showed the stuff the audience was supposed to see.
All dual-headed graphics cards can do this: modern Mac laptops have Radeons, I believe, and PC laptops with the same hardware can do the same things. My 2002 laptop with a Radeon M graphics card certainly can.
