Hi @digigui!

You should use a 3840*2160px sized slider
https://smartslider.helpscoutdocs.com/article/1774-slider-settings-size
if you don’t want your (3840*2160px sized) image to be cropped, you need to use the same size as your image’s.

If you did it that way, please send me an export of your slider:

and let me check it out:
