Image size limits to 1200 x 1200 – how to change?

Hi
I’m on 7.54 and tries to make banners that are 2000 x 250px. I can upload them to the server but when trying to take the image into a Block or a Custom content pane the image will be reziesed to max 1200 x 1200px

I’ve changed in IMCE but it does not help and I just can’t figure out where the limitations are set. Can pls anyone help?
