An apparatus for compensating a projected image employs a projected image compensator, such as a suitably programmed graphics processor or other processing device, and receives projection display compensation parameters to perform electronic projected image correction based on the received projection on display compensation parameters. The projected image compensator obtains stored final image data, such as data finally rendered by a 2D or 3D graphics engine, that has been stored in a frame buffer, and performs scaling of the final image data to produce projection compensated final image data. In one embodiment, the projection compensated final image data is stored back in the frame buffer memory and then output under control of a display controller. In another embodiment, the projection compensated final image data is not returned back to the frame buffer memory.
