Increase the quality of displayed image on anvil

I’m trying to set an image of high resolution (4928x3264) to be a cover image of the homepage. While the resolution is high, the displayed image has a very poor quality, like in the screenshot. How can I retain the quality of the original image?

~~ Edit ~~
I’ve tried: use fill_width mode and set full_width_row to True. The image still remains too blurry.

Hello there,

In the template for a question on the forum you should be seeing a section on “what you’ve tried”. If you are able, please fill that out in the future so folks can provide better assistance.

Have you tried searching the forum for “image resolution” or related terms? I’m fairly certain there are a few posts on that that might be helpful.

Thanks, I edited the topic!
