Header image looks wrong on explorer

Hello goodmorning to all who read this post.

I have a question about the header image. Some way some how it looks very weird on explorer. I know dont use explorer but there are still people using explorer.

On Chrome it is showing correctly. I have a Header image with a text on it so thats great. But on explorer it looks like the picture is zoomed in totally.

I don’t like that but I really dont know how to solve this matter. Does anyone have an idea how to solve this.

Oh and also important it is on the pages what are not the frontpage. So, The frontpage is showing the header video and the other pages should show the header image.

Please feel free to have a look: Link to a page what is not frontpage

Any advice will be highly appreciated.

Sorry for any bad English.
