Permanently center header banner image

Hello,

I am trying to have my header image always centred. Currently the issue I am having is that with change in display (from 13 inch screen to 22 inch screen) the header placement shifts so the text (that should be in the middle always moves, depending on display size. I have tried several ways including cropping the image to the exact pixel size recommended.
