How do you promote a grand opening on digital signage?

Open on the date and the address, full screen, before anything else. A logo tells a passerby nothing they don't already know; a date tells them to come back. Digital signage runs on a loop with no sound and no scroll, so the first frame has to work standing still, from ten feet away. Put the opening day and the street name in large text over a shot of the storefront or the space inside. Keep it to fifteen seconds so it loops twice a minute, and cut the rest — a countdown line, one line about what's inside, an end card that repeats the date.
