How to set up digital signage on a TV, step by step

What you need before you start

• A TV or display with a free HDMI input. A consumer TV is fine to start; for screens that run 12 hours or more a day, a commercial display is built for the workload.
• A media player — the small device that plays your content. Options are compared below.
• A network connection. Wi-Fi works; wired Ethernet is more reliable where you can run a cable.
• A power socket near the screen for both the TV and the player.
• A digital signage account — the cloud software where you upload and schedule content.
• Your first piece of content: a landscape image or video at the TV’s resolution (1920×1080 for Full HD, 3840×2160 for 4K) is the easiest starting point.

Choose how the TV will play content

The player matters more than the TV. Here is how the common options compare.

Setup steps for each type of player

Option 1: Amazon Fire TV Stick or Fire TV Cube

1. Plug the Fire TV device into a free HDMI port on the TV. Power it from the supplied adapter, not the TV’s USB port, which may not deliver enough power.
2. Switch the TV to that HDMI input and follow the on-screen setup, including connecting to Wi-Fi.
3. Let the device finish any software updates before continuing.
4. Install your signage player app and open it. It should display a pairing code.
5. In the device settings, turn off the screensaver and any sleep timer so the player stays on screen.
6. Pair the screen from your signage dashboard, then publish content.

Option 2: Android TV stick, box or built-in Android TV

1. For a stick or box, plug it into HDMI and power. For a TV with Android TV built in, skip this step.
2. Complete the Android setup and connect to Wi-Fi or Ethernet.
3. Check the Android version is 8 or later and install any system updates.
4. Install your signage player app and open it to get a pairing code.
5. Disable the screensaver and sleep options in the display settings. If the device offers a setting to launch an app at startup, point it at the signage player so it reopens after a restart.
6. Pair the screen from your dashboard and publish.

Option 3: Raspberry Pi 4 or 5

1. Write Raspberry Pi OS to a good-quality microSD card from another computer.
2. Put the Pi in a case with cooling — it will run all day behind a screen — and connect it to the TV with the correct micro-HDMI cable.
3. Connect a keyboard and mouse for the first boot, plus Ethernet if available, then power it with the official-spec power supply.
4. Complete first-boot setup, connect to the network and install updates.
5. Install your signage player and set it to start automatically when the Pi boots.
6. Note the pairing code, pair the screen from your dashboard, then disconnect the keyboard and mouse.

Option 4: Smart TV with a web browser

1. Connect the TV to your network and install any firmware updates.
2. Open the TV’s built-in browser and load your signage provider’s web player.
3. Switch the browser to full screen and note the pairing code.
4. Pair the screen from your dashboard and publish.
5. Test overnight. If the TV closes the browser or drops to its home screen after a while, a plug-in player stick is the more dependable choice.

Option 5: Windows or Mac computer

1. Connect the computer to the TV by HDMI and set the display to mirror or use the TV as the only screen.
2. Install the signage desktop player and set it to launch at login.
3. Set the computer to sign in automatically, and turn off sleep, screen savers and display power-off.
4. Schedule operating system updates outside opening hours so the screen does not restart mid-day.
5. Pair the screen and publish.

Set up the TV itself for all-day signage

Most “my screen went blank” problems come from TV settings, not the software. Go through these once on every screen:

• Disable sleep, eco and auto-off timers. Many TVs switch off after a few hours without remote-control input.
• Enable auto power-on (sometimes called power-on behavior or last-state memory) so the TV turns back on after a power cut.
• Enable HDMI-CEC so the player can wake the TV and switch it to the right input. Brands give CEC their own names; look in the input or external device settings.
• Set the default input to the player’s HDMI port.
• Turn off overscan (often “just scan” or “screen fit”) so edges of your content are not cut off.
• Hide the remote. In public spaces, the easiest way to keep a screen on is to stop anyone else changing it.

Mounting, cables and placement

Mount the player behind the TV with adhesive strips or a small bracket so it does not dangle from the HDMI port; a short HDMI extension reduces strain on the connector. Keep the player out of direct heat from the TV’s vents. Place screens at eye level where people naturally pause — at the counter, in the queue, beside the entrance — and avoid spots where windows reflect directly onto the glass. Portrait screens work well for menus and posters, but check that your mount and player both support rotation.

Your first content

Keep the first playlist simple: three to five slides or a short video loop, readable from where people will stand. Large text, high contrast and one message per slide beat dense layouts. Then add scheduling, so the screen shows the right content at the right time without anyone remembering to change it.

Setting up a TV with DigiSignWall

DigiSignWall’s player runs on every option above: Android 8+ TV boxes, sticks and Android TV panels, Amazon Fire TV Stick and Cube, Raspberry Pi 4 and 5, smart TVs with a browser via the web player, Windows and macOS, and touch kiosks. Install the DigiSignWall player, open it, and it shows a six-digit pairing code. Enter that code in your dashboard and the screen is yours. Setup typically takes under 30 minutes.

From there you build content in the browser with the drag-and-drop editor, or describe a layout to the AI assistant and approve each component it adds. Publishing typically reaches the screen in under a second, the player acknowledges delivery, and content is cached so it keeps playing if the network drops. The dashboard shows each screen’s health and a live view of what it is playing.

Your first screen is free, with no card and no time limit — see what the free plan includes. Pro adds up to 25 screens for $29 a month.
