"Responsive" Option Cuts off slider

I’ve been able to add in images of different sizes to see how they work. I’ve set up the settings to be able to handle an image that’s 1600×550 (for larger screens). But when I make it “responsive” it always cuts off a small portion of the image on the right side. Any advisement would be much appreciated. Thank you~
