Header Slideshow images resolution

Hello! I am using Syndey Theme with the latest WordPress version.
For the homepage slideshow I am using some images with resolution 1980px x 1275px. However, when I view the homepage on desktop I see the images zoomed in. Is the above resolution the appropriate for the slideshow of this theme?
