Media Carousel Image Size Problem

Hello, I am using an elemantor pro plugin and i want to add media carousel to my website.

I have tried several images size from 1920×1080 to 1920×1920 but it never resize images to screen.
For example one image look great on desktop but looks like some one crop the image top or sides on other screens.

How can i solve this? What size of image should i use it so it can resize it properly.
