Full-width Easy Slider image resolution issue

Hi,

I’m having trouble getting sharp images for my full-width Easy Slider banner.
I’ve read all the forums and have disabled all image compression plugins and added this code to my functions.php in order to disable image compression:

add_filter(‘jpeg_quality’, function($arg){return 100;});

However, my images are still coming out a little unsharp.
I’m using the Entry Without Sidebar image size (1210×423). Here is what I suspect the problem is: when I export images for these dimensions (1210×423), no matter how high the image quality I set for the export (I’m using Photoshop), the image is still coming out too small, because it’s only 1210 pixels wide. However, when I export the image a little bit larger (e.g. 1815×635) and upload this to WordPress, it comes out as even more pixelated than the smaller size. So either I need a way of adding another image size category (e.g. 1815×635) to the WordPress options in the Easy Slider menu panel, or I need to figure out what is going on that makes larger images appear even more pixelated than smaller images when adding them to the full-width Easy Slider.

Can anyone help?
