Selecting the aspect ratio
The 'aspect ratio' is the ratio of the image width to the image height. For SP840, the default aspect ration is 16:9. Most analog TV and computers are in 4:3 ratio, and digital TV and DVDs are usually in 16:9 ratio.
With the advent of digital signal processing, digital display devices like this projector can dynamically stretch and scale the image output to a different aspect than that of the image input signal.
