I think that a video card stores just the current screen, not all the
virtual screens. Window manager, which usually implements virtual screen,
should use heap memory to save virtual screens.
Therefore, a video card uses vertical pixels * horizontal pixels *
color depth.

If you use hardware accelerated OpenGL, it's much more complicated
though. (ie texture, accumulation buffer, stencil buffer, etc.)
