DSMS Player

Install this screen as an app on this computer. It gets its own DSMS Player icon that opens straight to this screen, full screen.
🔊 Let it play sound by itself (music, narration, videos with sound) — otherwise sound waits for a tap, and is lost again whenever the screen updates. On Windows: download the sound setup, open it, click Yes, then close and reopen Chrome or Edge. (Works for both.)
