The video resolution of the projected image is 1024 × 768 pixels (4:3 aspect ratio). When 
RGB is input from a computer and projected by the projector, the input image is enlarged 
or reduced automatically to match the video resolution of the projector. How the 
enlargement and reduction is performed depends whether the aspect ratio setting is “4:3” 
or “Maintain” (page 9).
The following shows how images are projected in accordance with the resolution of the 
input signal from the computer and the aspect ratio setting of the projector.
