You can have Incident Review automatically update by running a real-time search. This will show updates automatically in real-time.
But I only want Incident Review to show notable events created from now on
Run an all-time real-time search if you want Incident Review to show all notable events that are created after the start the search. This works because an all-time real-time search doesn't back-fill; it will only show things coming in from now on.
But I want to show this on a big screen along with other dashboards
In this case, you may to consider using the Slideshow app. That app allows you to create shows consisting of a series of dashboards. It also supports a "dark-mode" that loos nice on a big-screen. Another option is using a browser plugin to cycle through dashboards.
