Although Amazon Prime Video doesn’t support adjusting video aspect ratio, you can change the picture size from the device that includes the Prime Video app.
On your device, i.e., smart TV, PC, tablet, or game console, go to Settings and change the aspect ratio to 16:9 for full screen or 4:3 for VHS or SD broadcast.
