Hi there,
I took a look at your website, and first off, wow! What incredible photos!
Secondly, I’m not sure if what I’m looking at is blurry. Here are a few screenshots from what I can see:

Do those screenshots also look blurry to you? (because they are GORGEOUS on my computer!)
If they do not look blurry, I would suggest viewing it in another browser or clearing your browser’s cache, as a local copy may have been saved (blurry) to your computer’s cache to cut down on loading times.
If it’s not that, it could also be an issue if you’re using a plugin to optimize your images, or if your featured images are too small for the theme you’re using and being expanded to fit the space. ?? You might check out your specific theme’s documentation to make sure your image fits the recommended pixel requirements.
Please note that I am also on a laptop with no attached monitor, so on a larger monitor, you may need to use even larger images if you have them, as the images might stretch (causing the blur) to fit the screen size.
I hope that helps!
