Black bars exist to preserve the original aspect ratio of content. When the aspect ratio of a video's source doesn't match the display's aspect ratio, black bars are added to fill the unused screen space. This avoids distortion or cropping, ensuring that you view the content as originally intended. They are commonly seen in movies shot in widescreen formats displayed on standard TVs or monitors.
