What is digital signage? Meaning, how it works and what it costs
Digital signage is the use of screens, such as TVs, monitors, LED displays and video walls, to show content like menus, prices, notices, promotions or video that you change from a computer instead of printing and hanging new signs. A digital signage system has three parts: a screen, a small computer called a media player that plays the content, and software where you decide what plays on which screen and when.
You will also hear it called a digital sign, a digital display or, in the Netherlands and Belgium, narrowcasting. The screen on a restaurant wall that shows today's specials, the TV in a clinic that shows opening hours and the display in an office lobby that welcomes visitors are all digital signage.
We make Screenbird, digital signage software for small and medium businesses, so we explain it from that angle: what it is, how the pieces fit together, which kinds there are, where it is used, what you need to buy and what it honestly does not solve.
In short
- Digital signage is a screen that shows content you manage remotely, so changing a price or a notice takes a minute instead of a reprint.
- You need three things: a screen, a media player (a stick, a small box or a PC) and signage software to manage the content.
- Content is stored on the player, so a screen keeps playing when the internet drops. Updates and live data need a connection.
- A TV alone is only the screen; signage adds scheduling, remote control and a player that is built to stay on.
- A small business can start with one screen you already own and a player of about USD 100; Screenbird is from $14 per screen per month.
How does digital signage work?
Every digital signage setup, from one screen in a cafe to hundreds across a chain, is made of the same three parts, connected by your network. What changes is how many there are, not how they fit together.
The screen
Any display with an HDMI input: a regular TV, a commercial display, a monitor, an LED panel or a video wall. The screen only shows the picture it is given.
The media player
A small computer on the back of the screen. It downloads your content, stores a copy and plays it over HDMI. It can be a stick like the Amazon Signage Stick, a Google TV Streamer, a Raspberry Pi, a mini-PC, or the smart TV itself.
The software
Also called a content management system or CMS. You use it in a browser to upload content or make designs, group them in playlists, set schedules and send them to the right screens.
The network that connects them
The player connects over Wi-Fi or a cable to the software, collects what you changed and reports in. After it has downloaded your content it can keep playing without a connection.
In practice it goes like this. You make or upload a menu, a notice or a video in your dashboard. You put it in a playlist, and you send the playlist to a screen or to several screens at once. The player on each screen downloads the files, stores them and plays them in order. When you change something in the dashboard, the player picks up the change and the screen follows, usually within seconds.
What happens when the internet drops
In Screenbird, designs and uploaded images and videos are stored on the player, so the screen keeps playing them without internet and syncs again when the connection returns. Content that is live by nature, such as a web page or a spreadsheet, needs a connection to stay current.
Because most players boot by themselves and start your content again after a power cut, nobody has to stand next to the screen with a remote. That is the main difference between signage and a TV with a USB stick in it.
What does digital signage show?
Anything that fits on a screen and is worth a glance. Most small businesses start with a few of these and add the rest later.
- Designs made from templates: menus, prices, promotions, opening hours, welcome messages and notices. Screenbird has more than 250 templates in its Designer, in landscape and portrait.
- Photos and videos you upload, such as a product film or a looping brand video.
- Live content, for example a Google Sheet, a calendar, a web page or a dashboard, so the screen follows the source instead of being edited twice.
- Playlists that rotate several items, and schedules that switch content by time of day or week, such as a breakfast menu that hands over to lunch.

Types of digital signage
There is no single official list. The practical way to sort digital signage is by the kind of screen, because that decides what you buy, where it can hang and what it costs.
| Type | What it is | Where it is used | Good to know |
|---|---|---|---|
| Single flat screen | A TV or commercial display, landscape or portrait | Shops, cafes, offices, waiting rooms, schools | The most common setup and the easiest start. A regular TV works for many small businesses. |
| Video wall | Several screens or panels tiled into one large picture | Lobbies, stores, control rooms, events | Needs matching panels and a way to split one picture across them. |
| LED display or LED board | A large panel of LED modules, often fed through an LED processor | Stadiums, sports halls, shop fronts, big venues | Brighter and larger than a TV, usually at a higher cost. |
| Outdoor display | A high-brightness, weather-sealed screen | Shop fronts, drive-throughs, entrances, forecourts | Needs a display made for outdoor use. A normal indoor TV in a window is not the same thing. |
| Window display | A screen facing outward through glass | Shop windows, restaurants, estate agents | Must be bright enough to read in daylight. |
| Interactive kiosk | A touchscreen the visitor operates | Wayfinding, self-service, ordering, information points | Needs software built for touch. A plain signage player is for content that plays by itself. |
| Tablet on a wall | A tablet used as a small screen | Reception desks, meeting room doors, small displays | A cheap way to add a small screen where a TV would not fit. |
Prices vary a lot by size, brightness and brand, so none are quoted here.
Indoor versus outdoor is the big divide inside that table. Indoor screens are made to be read in controlled light and a stable temperature. Outdoor and window-facing screens have to compete with sunlight and cope with weather and heat, so they are brighter, sealed and built differently. If a screen faces the street from inside a window, check the brightness before you buy.
Whatever the screen, the player and the software work the same way. Screenbird, for example, runs on Android devices, a Google TV Streamer, the Amazon Signage Stick, Windows, Mac and Linux computers, a Raspberry Pi, many smart TVs through the built-in browser, and any modern browser. It is made for screens that play content. For LED walls, Screenbird has Pixel Mapping to send a wide picture in pieces to your LED processor.
What is digital signage used for?
Wherever people wait, walk past or arrive and the message changes often enough that printing it is a chore. Each card below leads to a page with the setup and templates for that use.
Shops and retail
Promotions that start and end on set dates, new arrivals and a window screen that switches to opening hours after closing.
Restaurants and cafes
A digital menu board with prices you can change in a minute, a daily special and breakfast and lunch menus on a schedule.
Offices and lobbies
A welcome for visitors, internal news and key figures on a screen in the hall or the staff room.
Waiting rooms
Opening hours, Wi-Fi details and a health tip for people who are going to sit for a while anyway.
Schools and education
Timetable changes, events and announcements in the hallway and the staff room.
Hotels
A welcome, breakfast and restaurant hours, and facilities such as the spa or the pool.
Gyms and studios
The class schedule, the next class and studio news on a screen nobody has to look after.
Apartment buildings and directories
House rules, notices for residents and a list of who is on which floor.
All use cases
Including in-store promotion, shop windows, directories and internal communications.
What do you need, and what does digital signage cost?
The cost has two parts: the hardware you buy once and the software you pay for per screen. The hardware can be close to nothing if you already own a suitable screen. The software is an ongoing subscription with most providers.
| Item | What it is | What to expect |
|---|---|---|
| Screen | A TV, monitor or commercial display with HDMI | You may already own one. Commercial and outdoor displays cost more than a TV; check a TV's warranty if it will run all day in a business. |
| Media player | A stick, box or computer behind the screen | A stick or box is about USD 100: the Amazon Signage Stick lists at USD 99.99 in the US as of October 2026, and the Google TV Streamer launched at USD 99.99. A computer you already own can do the job. |
| Software | The CMS where you manage content | A subscription, usually per screen per month. Screenbird is from $14 per screen per month, with every feature included. |
| Mounting and cables | A bracket, an HDMI cable and a power point | Small items, plus a mounting job if the screen goes on a wall. |
| Internet | Wi-Fi or a network cable | Your existing connection is enough for most setups. Screens need it to download and update content. |
| Content | The menus, notices and videos themselves | Made in the software's designer, so no design tool or agency is needed to start. |
Only the Amazon Signage Stick and Google TV Streamer prices are quoted, both from the vendors. Prices differ by country and store.
Screenbird is a paid subscription with a 7-day trial: you can try everything for 7 days, a credit card is required to start, and after that it costs from $14 per screen per month on a yearly plan. Screens on different locations are managed from one dashboard.
If you want one recommendation for the player, we suggest the Amazon Signage Stick, which Amazon built for 24/7 signage and which runs only one app; the Google TV Streamer is the alternative. The player guide compares them with a Raspberry Pi, a PC and a smart TV.

Advantages and disadvantages of digital signage
Digital signage is a good fit for some messages and a poor one for others. These are the honest trade-offs.
Advantages
What digital signage does better than print.
- Changes take a minute and reach every screen, so no reprinting or driving to a location.
- Scheduling puts the right content at the right time, and an end date takes an expired offer down by itself.
- Video and rotating content can draw the eye in a way a static poster does not.
- One dashboard can run one screen or many, across several locations.
- Costs are predictable: a player once and a subscription per screen.
Disadvantages
What to weigh before you start.
- A start-up cost for the screen and player, and a subscription on top, where a poster has none.
- Content needs an owner. A screen that shows last month's news is worse than no screen.
- Screens and players can fail, and a power cut or a Wi-Fi change can take a screen offline until it is fixed.
- A bad setup hurts: small type, low contrast or glare make a screen hard to read.
- Not every message needs it. A sign that never changes can stay a printed sign.
Is digital signage worth it for a small business?
It is worth it when something on your wall changes more than a few times a year, and printing, cutting and hanging it costs you time. Typical cases are a menu with changing prices, a shop with regular promotions, a waiting room, a gym with a class schedule or an office with visitors.
It is less obviously worth it for a message that never changes, or when nobody has the time to keep the screen current. Start with one screen and one job, such as the menu or the opening hours, before you put screens everywhere.
Small businesses also do not need the enterprise route. You do not need an installer, a server or a contract to run a few screens: a screen you own, a player of about USD 100 and a subscription is the whole setup. The comparison of digital signage software covers which one to pick.
How to get started with digital signage
Pick the one thing the screen should do
A menu, the opening hours, a promotion, a notice board. One clear job makes every later choice easier, and you can add more once it works.
Choose the screen and where it hangs
Landscape or portrait, within reach of power and Wi-Fi, and where the people you want to reach actually look. Check the glare at the time of day when most people pass.
Choose the media player
Use a smart TV or a computer you already have, or buy a stick. We recommend the Amazon Signage Stick, with the Google TV Streamer as the alternative.
Pick the software and pair the screen
Make an account, connect the player and enter the 6-character pairing code that the screen shows. In Screenbird, pairing takes a few minutes.
Make content and send it
Start from a template, change the text and pictures, and send it to the screen. Add an end date to anything that expires, and a schedule for anything that depends on the time of day.
