Ablesign: show the display screen with Chromecast

This guide gets the What When Where display screen onto a TV using a Chromecast.

What you need

• A Chromecast set up on the venue's wifi.
• Your town's screen address (see Display screen).

What is supported

The screen has been built for Chromecast "web browser" and Ablesign players. It boots straight into the address, and the old site's screens used the same kind of address, so venues that already have a screen pointed at their town's address keep working.

TODO (client): Write the Chromecast steps: whether the venue casts a browser tab or uses a signage app, how to start it again after a power cut, and how to keep it from going back to the home screen.

TODO (client): Add real-device screenshots and the Ablesign steps.
