A Raspberry Pi costs very little and turns any display with HDMI into a digital sign. Setup takes about fifteen minutes and you edit one file.
Use Raspberry Pi Imager on a PC and choose Raspberry Pi OS (64-bit). Enter a username, password and Wi-Fi in Imager's settings before writing the card.
Start the Pi, open Terminal and run sudo raspi-config. Choose System Options → Boot / Auto Login → Desktop Autologin, then Display Options → Screen Blanking → No.
Open the file .config/labwc/autostart in your home folder, for example with nano .config/labwc/autostart, and add this line: chromium https://skjermly.no/player --kiosk --noerrdialogs --disable-infobars --no-first-run &
Run sudo reboot. The Pi signs in and opens Skjermly full screen.
The screen now shows a six-character code and a QR code. Sign in to Skjermly, go to Screens → Connect screen and enter the code, or scan the QR code with your phone.
Send us the model number of the display and we'll send you the right menu steps for that exact model.
