A digital signage pre-launch checklist

A costly digital-screen mistake is often a message nobody can read, an expired offer left in the loop, or an online player connected to a television on the wrong input. Run the seven checks below on one display in the real space before assigning its content anywhere else.

1. Does one scene carry one clear message?

Stand where a visitor stands, look for a few seconds, then look away and name the main information. If you remember three headlines, two prices and four calls to action, the hierarchy is unclear. Remove anything not needed for the decision made in that place. Detail can live on a later scene, in a PDF, or behind a QR code.

2. Is the text readable at the real viewing distance?

A laptop preview is deceptive. Publish a test, stand where people pass or wait, and check the headline and price. Look for glare, bright photography behind text and thin letterforms. If you must step closer, shorten the copy and then enlarge it. Make the final decision in the room; use the typography guide for a detailed calculation.

3. Do the asset and display share an orientation?

A landscape photograph on a portrait panel can lose the important part of the frame or leave a large empty area. The SignageWall player supports orientation and content-fit settings, but a setting cannot rescue a badly framed original. Check every image and video in the aspect ratio that will actually be mounted. Do not assume one file works equally well in a window, above a counter and in a corridor.

4. Will the final files pass through the real publishing flow?

For uploaded media, the current system accepts supported image and video formats with a 10 MB limit per file. Video can be MP4, WebM or QuickTime, and processing prepares it for playback when needed. Upload the exact final file; the extension shown by your computer is not a sufficient test. Wait for processing to finish and open the preview before adding the item to several screens.

5. Does the duration fit the location?

There is no single correct duration for every slide. A passer-by has less time than somebody in a waiting room, while a short price is read faster than a three-step instruction. Read the words aloud at a normal pace, add time for the eye to find the headline, and then inspect the whole loop. If a scene has to remain for a long time only because it contains too many words, shortening the message is a better fix than extending its duration.

6. What remains visible when the network disappears?

SignageWall persists the last content snapshot and prefetches images and video, so offline-safe items can continue. Apps that depend on a live remote page or stream are skipped without a connection. Disconnect the network during the test and watch the whole loop. Repeat the check after restarting the player. If every item needs a network, add at least one local or cached item instead of expecting a stream to work offline.

7. Who keeps the content accurate?

Set screen working hours so the player enters standby when the space is closed, and give campaigns an owner and a review date. The current schedule controls when the screen plays; it does not expire one slide automatically, so an old promotion still needs an editorial decision. In the dashboard, check online status and the last time the device reported. Those signals confirm connectivity, but they do not prove that the television is on the correct HDMI input or that the message is readable.

The final check lasts one complete loop

Play the content from beginning to end on the target display without skipping. Record only what a visitor could notice: an empty scene, a harsh transition, an unreadable price, a network app that vanishes, or a message that repeats too soon. Fix those points, run the loop again, and only then assign it to the other selected screens. The checklist does not replace specialist design and technical guides; it stops an obvious fault from reaching the wall.
