What is digital signage?
A screen that shows what you tell it to, and changes the moment you change your mind. This guide explains the whole thing from scratch: no jargon, no sales pitch.
The short answer
A digital signage screen is a display in a physical space that shows content you control remotely: a menu, a price list, an offer, a waiting room information screen or a departures board. Unlike a printed poster, its content can be changed from a browser. Unlike an ordinary television channel, it follows the ordered media, playlists and apps assigned to it, within the screen’s configured working hours.
Where you have already seen it
The menu board above the counter at a fast-food chain. The screen in a pharmacy showing which number is being served. The board in a hotel lobby listing today's conference rooms. The window display in an estate agent's office that cycles through properties. All of it is the same three pieces doing the same job at different sizes.
The three things you need
A screen, a player and software. The screen is usually a television you already own: any digital display with an HDMI input works. The player is a small device that plugs into it: an Android box the size of your hand, a mini-PC, or a computer already sitting nearby. The software is what you use to decide what plays and when, from a browser, anywhere. That is the entire shopping list.
What the player actually does
It downloads your content, stores it locally and plays it in a loop. Storing it locally is the part that matters: when the internet drops, a player with a copy keeps going, while a player that streams shows a blank screen or an error to everyone walking past. Ask about this before you buy anything, because it is the single most common way a signage setup embarrasses its owner. If you are choosing the box itself, which digital signage player to buy is its own question.
What it costs
Three separate numbers, and vendors tend to blur them. The screen you probably own. The player is a one-off purchase, typically between €50 and €200 depending on whether you need a cheap Android box or a mini-PC that runs sixteen hours a day. The software is a monthly subscription per screen: the market sits between €8 and €45, and the range mostly reflects how much a vendor holds back for higher plans. SignageWall is €8 per screen with everything included.
How long it takes to set up
The first screen can be set up quickly. Plug the player into the screen and power, install the app, then enter the six-character registration code it shows in the dashboard. Building the first piece of content (a menu, a price list or a welcome message) usually takes longer than pairing. Every screen after the first can reuse existing content by adding it to that selected device.
What to put on the screen
Less than you think. Good signage content says one thing: a screen that tries to say six says none of them, because a passer-by gives it a second or two. Pick one message per item and make the text large enough to read from where people actually stand. Current SignageWall supports working hours for the whole screen, not automatic breakfast, lunch and evening item switching, so any daypart change needs a supported external source or a manual content change.
How to tell whether it is working
A screen has no built-in click-through rate, but you can still define an external measure. Track the sales of a featured item in your point-of-sale system or count how often staff receive the question the screen should answer. For a QR code, use analytics on the destination or a trackable URL provider; SignageWall does not count scans itself. Pick the measure before publishing so the comparison is honest.
Common mistakes
Pushing the same content to every screen in a building, when the customer at the window and the customer in the queue are thinking about different things. Text sized for a designer's monitor rather than for four meters away. A static logo burnt into the corner of a panel after a year. Buying a professional display when an ordinary television would have lasted years, or the reverse. An ordinary television in a sunlit window, where it will never be bright enough.
Where to go next
If you want to see what it looks like for your kind of business, digital signage solutions by industry walk through specific setups. If you want to know what the software itself does, the digital signage CMS is described feature by feature, and how digital signage works in three steps covers getting a first screen running. If your question is narrower than any of that, such as how long a slide should stay up or where a screen belongs in a shop, the digital signage guides take one at a time. If you want the numbers, digital signage software pricing is published without a sales call. If you would rather just try it, a trial takes a few minutes and needs no card.
