For stages without proper screening area, there is an option to screen surtitles into mobile devices or other computers. This screening requires internet connection, but consumes very little data (for each connected device it's less than 1MB per hour of screening).
Mobile screening may be opened on any device supporting internet browsers. It may be used for screening to remote projection too.
There's also a mobile app which automatically reduces brightness of display it's running on. Try the app on the AppStore.
In combination with proper adjustments of your marketing, you will sell more tickets.
