Step 1: check the TV
Confirm the TV can stay on during opening hours, has enough brightness and can display a browser or external player reliably.
If the screen faces sunlight or runs very long hours, consider a commercial display.
Step 2: choose the playback method
You can use a smart-TV browser, a small media player or a dedicated signage device. The simplest reliable option is usually better than a complex setup nobody can maintain.
Test auto-start, Wi-Fi stability and what happens after a power outage.
Step 3: design for distance
Menu boards are read from several meters away. Use fewer items per screen, strong contrast and large prices. Avoid tiny descriptions and overloaded images.
A menu board is not a PDF on a TV.
Step 4: update products centrally
The real benefit appears when prices and availability can be updated once and reused in QR menus, table ordering and social media. That reduces mistakes during busy service.
