MMM-PlexSlideshow is working when I view MM through a browser from a remote computer, but when displayed through HDMI on a display every module works except MMM-PlexSlideshow.
I have it set like this in the config

                {
                        module: 'MMM-PlexSlideshow',
                        position: 'fullscreen_below',
                        config: {
                                plex: {
                                        hostname:"",
                                        port:32400,
                                        username:"",
                                        password:"",
                                },
                                transitionImages: true,
                                backgroundSize: "contain"
                        }
                },
