What you need

A TV, a small box, and the wifi password once

This is the question every gabbai asks first, so here is the whole answer before you have to ask for it — including the parts that are usually left out until after you have paid.

The three things

A screen Any TV or monitor with an HDMI socket. Fifty to sixty-five inches suits most shul walls. The board sizes itself to whatever it is plugged into — there is nothing to configure for your particular screen. If the shul already has a TV, that is the screen.
A device A small box that plugs into the HDMI socket and draws the board. $180 once. We buy it, set it up with your shul's board already on it, and post it to you. It is not a computer anybody has to manage.
Wifi, once Joined to the shul wifi the first time it is switched on. After that it looks after itself.

The questions that actually matter

What happens when the wifi goes down?

It keeps working. The zmanim and the Hebrew date are worked out on the screen itself, and the last saved times are held on the device, so a dropped router is not a blank wall. New edits arrive when it is back.

What happens after a power cut?

It comes back on by itself and goes straight to the board. Nobody signs in, nobody finds a remote, nobody is asked to pick an app. That is the whole point — a board that needs a person after every outage is a board that spends half the year showing a screensaver.

Who has to look after it?

Nobody, on the wall. Everything that follows from the date takes care of itself. The only thing a person does is change what only a person knows — minyan times, a shiur, a notice — and that is done from a phone, not from the screen.

How does the gabbai change the times?

He signs in to your shul's own page on his phone, types the change, and the wall has it inside a minute. It is built for a phone, because that is what is in his pocket when he notices mincha has moved.

Can we put our own photographs on it?

Yes — a photograph for a Yom Tov, a notice, a picture of the shul. Every Yom Tov also arrives with its own artwork already, so a shul that uploads nothing still gets a proper screen on Pesach.

What if we are not a Chabad shul?

Chabad or Ashkenaz. The Chitas and Hayom Yom screens can be turned off and everything else stays. What is on the Chabad screens.
