It could be due to incorrect settings of Slider Revolution plugin, you should recheck the slider settings again.
Since it’s only happening in slider the issue could be generated from that plugin so you should contact their support.
It’s that way in the media gallery too.

How do you get to “the media gallery”?
What version of WP are you using?
Do you have plugins that affect the Media Library?
Upon image upload, WordPress generates copies of the image to correspond to the Media Setting sizes. When a request is made for an image with a size, WordPress calculates which generated image to use based on it being the smallest one that is at least as big as the size requested. It doesn’t enlarge images.
The theme, however, can and often does define image sizes that have nothing to do with the original images, and can also use CSS (like width: 100%) that makes images look blurry. Slider plugins can fall into this trap also.
The media gallery is in the left menu “media.” In there the image is displaying too large. I don’t get how WP can even do that. I upload at 620px and it displays it at 680? I am using Divi and Elementor. I’m digging through the settings trying to disable the Divi “use Divi media gallery” and anything else that seems related. So far nothing is working.
It must be the theme.

I switched to the Twenty Twenty theme and regenerated the thumbnail of an image, and even deleted and reuploaded it. Still looks blurry and is resizing bigger than it is.
OK, so I tried making a smaller image, 500px, and uploaded it. It looks much blurrier than how it looks in Photoshop and Windows Photos preview. This is making ZERO sense to me. I’m about to start banging my head against the wall.

I think the problem is in either Divi or Elementor. WordPress has one menu item called “Media”, which is the Media Library. It has both a list and grid view. Neither one show the image larger than the uploaded image.
If you click on the image you see it larger. In there it is larger than my uploaded image. However, when I made a smaller one and uploaded it, it was actually smaller but still blurry. Also, I disabled both Divi and Elementor.

I just opened one of the images in an empty Chrome browser page and it looks sharp. I then uploaded the image to the root directory of my site https://whittsrentals.com/sandstone-620.png and it looks blurry there, even outside WordPress. How can that be? How can an image look crisp displayed froma local file in my browser but be blurry just sitting in the root of my website folder? I mean, it can’t be the web server compressing the image can it? That would be really lame. As far as I know there isn’t any software that would do this on my server.

SO… it appears I tried everything BUT the simplest solution. The one I should have started out with. EMPTYING MY BROWSER IMAGE CACHE. Uhg. A whole day of troubleshooting and all I needed to do was empty by browser cache.
