The images on my collection pages (using product grid) appear fuzzy as compared to much clearer on the single product page. I am using a theme called HONGO. In edit code, I have a file called main-collection-product-grid.liquid, I also have featured-collection.liquid, collection-list.liquid, and main-list-collections.liquid. Any tips would be greatly appreciated.
Check the “image_url” or “img_url” tags used on your collection pages and check in which resolution the images are being rendered. It’s usually a good idea to set the dimensions to twice the rendered size so they look good on retina displays.
Just check what dimensions are used there and increase them. You could also check HONGO theme’s docs or contact their support team. They might have a setting where you could change that without touching the code.
