# Support high-DPI retina displays
Standard images look blurry on retina displays (2x, 3x pixel density)—high-resolution assets ensure sharp visuals on modern devices.
## Quick Reference
- Provide 2x and 3x images for high-DPI displays
- Use srcset with x descriptors for fixed-size images
- Use srcset with w descriptors for responsive images
- CSS background-image: use image-set() or media queries
## Check
Check if high-resolution images are provided for retina displays (2x, 3x).
