Background image in rows is blurry

I’ve been trying to add background image in Row section, however the image becomes blurry after uploaded (image resolution is confirmed large enough and is normal in gallery view).

Problem occurs only to new added image or replacing an own image from a template. Site is not published yet.
Thanks for some tips. Michael

Thanks for the super fast reply! Appreciated. However, the result stays the same. Contained or not contained.
As a sample. I use at present the template “Animals Magazine pro” at https://photosafarisuganda.com and like to change the template’s background image on the top of the home page (https://photosafarisuganda.com/wp-content/uploads/2023/10/xxx_bg_home1_xxx.jpg)
Should be replaced by https://photosafarisuganda.com/wp-content/uploads/2024/01/Home-Zone-1.jpg which has the same file size and resolution is also 1 MB.

The result is not the same quality as the sample image of the template.
Could that be the WP Memory limit? .. which is set at 256 MB.

I would be greatful for a solution or idea how to solve that..

Thanks in advance Michael

For the rest I am using TAGDIV for years on various websites and its just great. This is the first site where I deal with the background images 😉

Thanks Anamaria. This was “Top of the Pops”! It works.
