Photo's are not in the right size

According to the Kreativa theme manual, I have to upload the photos with 1400 px.
According to the photo on the site that I want to replace, it says it must be 1400 x 932 px.
I adhere exactly to these dimensions and yet my photos are not fully placed. The width is usually right, but not the height. I keep trying; a bit from the bottom, a bit at the top, etc. to get the right area in view, but often I just don’t succeed either.
There must be a solution for this …? Can you help me please?
