Why is the hero image blurry in the Dawn theme?

Topic summary

A user encountered a blurry hero image in Shopify’s Dawn theme (v12.0.2), despite optimizing the image to 300 DPI and compressing it. Mobile images loaded fine, but desktop images remained blurry.

Proposed Solution:
A PageFly representative suggested modifying the image-banner.liquid file by changing the native resolution settings:

  • Navigate to: Online Stores > Themes > More Actions > Edit code
  • Locate and edit the image-banner.liquid file
  • Adjust specific lines (around line 48 onwards) related to image resolution

Resolution:
The user initially couldn’t locate the specified code lines but ultimately resolved the issue using the provided guidance. The discussion concluded successfully with the problem solved.

Using the Dawn theme and the hero image is super blurry. I’ve made the dpi to 300, compressed it and it still is super blurry. I’ve separated between mobile and web images - the mobile images load fine, but the desktop isn’t optimised.
