PageSpeed Insight Largest Contentful Paint image was lazily loaded

I got a pagespeed insight report and encountered a problem in the report. I think I’m having this problem because the slider doesn’t take up the left part of the screen. I tried some ways but it didn’t work, can you help please?

Pagespeed insights says that the largrst contentful paint image is being lazyloaded because your largest contentful paint image is being lazy loaded.
