Tech question regarding projecting an image from a laptop directly onto a screen. [View all]

Is there any technology out there that can, with good quality, project a background directly from a laptop file to a screen without using a projector. I am trying to visualize how it would work in theater production to have a moving background. What I anticipate is that it can't be done unless the screen is special made with pixulation technology.

I understand that this may be in the sci-fi hemisphere, so points for quess work and creativity.
