Aspect Ratio

The ratio of an image's width to its height. Most modern projectors and impact screens use 16:9 (widescreen), but golf simulator screens often use 4:3 to better match the vertical proportions of a swinging body and a ball flight that climbs.

Mismatched aspect ratios produce black bars or stretched images. Match your projector's native aspect ratio to your impact screen — a 16:9 projector on a 4:3 screen wastes pixels, and a 4:3 projector on a 16:9 screen crops the view.
