ABSTRACT:
A video system includes a video projector located in a housing a display screen disposed adjacent to the housing, wherein the display screen is capable of being tilted to expose the video projector, logic for generating a test image to display on the tilted display screen in order to calibrate the video projector, logic for projecting the test image onto the tilted display screen; and logic for calibrating the video projector using the test image. The test image is altered to fit the tilted display screen.
