[Question] Shopify page image

Any tips for placing a homepage image?
I'm using the Debut theme, I can't get the "Image with text overlay" image right.

Image size is 1200x400 as they recommend in the documentation.
My image has a text on it. If I set the "section height" to small, then it looks great on mobile view but looks shit on desktop or bigger screens.

If I set it to Medium or Large then it looks good on desktop but looks shit on mobile.

I'd like to keep the text on the image instead of doing a text overlay.
Any suggestions?

I had Debut theme when I started to customize a store but I had to change my theme for this try Brooklyn , Venture or Boundless theme
