How to connect the Photo Wall to external displays?
The Photo Wall is simply a web link that can be displayed on any device that has an internet browser (Chrome/Safari etc.).

The exact instructions depend on the setup you have (or the venue has), but here are some common ways to do that:
Connect with a cable (HDMI)
Connect to a smart TV
Connect via Chrome Cast
Connect via Apple TV
Connect via Amazon Fire TV Stick
💡 If you're having your event in a rented venue, you should talk with the host/manager. They probably can help you with that or handle this for you.
