Black bars can preserve part of the image
When a film’s shape differs from the screen’s, filling every inch may require cropping or distortion.
Aspect ratio is not resolution
Aspect ratio describes the relationship between width and height. It does not by itself indicate the amount of detail. A work can be wider or narrower than its display regardless of resolution.
Filling the screen has a cost
To keep the whole picture without distorting it, a player may leave empty areas above, below or at the sides. Enlarging to fill everything can crop edges; stretching changes shapes. These changes may remove gestures or objects important to the composition.
Check the framing
When you see bars, do not assume the video is faulty. Check whether the device offers the original aspect ratio. Compare the edges, not just the size of faces. Preserving the frame helps maintain the visual relationships chosen for the work.
