White Screen with nextgen gallery proslideshow and others slideshow gallery plugins

Hi!, I have problems with my Wordpress Content. When i try to load on screenly OSE assets with an URL that link to a web page with a nextgen galley proslideshow ( to have image slides fullwidth without white border on page), screnly shows only Display white. I tested it on Raspberry 3B+. Instead when i load assets with link to pages that contains nextgengallery slideshow base with same images it works fine (but with a white border on page). I think that the unique difference is eventuals javascripts that the screenly browser don’t recognize. Same problem appears with other slideshow plugins. My goal is to find a way to visualize an asset with images slideshow full width. (My Wordpress theme is Twenty Nineteen). Any idea or suggest?
