Graphics blurry until page zoomed in and out

Hi i'm a newb on latest WordPress with Elementor, and have a page with 6 graphics. When you visit the page, the graphics are just a bit fuzzy. Not as clear as they should be. But if you Ctrl+ a couple times, and Ctrl- a couple times, they pop back into a better clarity. I've tried on a couple browsers, on a couple PCs. Seemed fine when I checked on phone though. So it seems like it's not a problem with WP resizing or compressing the graphics too much, since they are fine after zooming in/out. Any ideas? Thanks!
