Install this screen as an app on this computer. It gets its own DSMS Player icon that opens straight to this screen, full screen.
In Chrome or Edge, click the install icon at the right end of the address bar (a small monitor with a down-arrow), or open the ⋮ menu and choose Install DSMS Player.
Not offered? Use Chrome or Edge, and make sure the address starts with https://dsmsdigitalsignage.com/play/.
🔊 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.)
