Question about the header image on the home page

Hi!  We're running PhotoFocus Pro 5.4 on Wordpress 6.2.2.  We recently changed the header image and noticed it's not appearing in its full height.  The new header image has dimensions 1920x1080.  The bottom of the image appears to get cut off.  On a high-resolution display, what is the maximum height of the area where the header image will appear?  Is it 1080px or something smaller?  Is there a way to get the full header image height to appear such that the image isn't cut off? You can see the current header image here: https://www.birthandbeauty.com/ The site is safe for work, but some of the images might be a little disturbing.  The header image, at the top of the home page, is the image in question and it's not disturbing at all.  :) On our home page, the mother's leg appears to be cut off at the bottom of the image. Thanks in advance for your assistance!
