Your CSS is causing this issue. The image you uploaded is 1400x500. You have a css attribute making the image width 100%, while height of the container is fixed at 499px. If you view this on a display wider than 1400px, it's going to stretch the image horizontally to fill the frame, which will change the image aspect ratio. Also, if the screen width is too narrow, it will crush the image horizontally.
The CSS will need some reworking to make it look right on all displays. Best alternative would be to make the frame height change relative to the image width.
