A social media wall is a screen at your event showing posts about your event, live. It gives attendees a reason to post, gives remote followers something to watch, and fills the large blank display behind registration that would otherwise show a looping logo.
The technical part takes about ten minutes. The part that decides whether it works is what you put on it, and that decision has to be made before the doors open.
Decide what the wall is for
Most walls fail because nobody decided this. There are three jobs and they want different setups.
Participation. You want attendees posting. Show the event hashtag, put the wall somewhere people queue, and keep the pace slow enough that someone can spot their own post. Seeing yourself on a large screen is the entire mechanism, and it stops working if posts scroll past in two seconds.
Information. Schedule changes, room moves, speaker swaps. This wall follows your own account and the organiser handles, runs faster, and belongs near entrances and lifts where people pass through rather than linger.
Atmosphere. A trade show booth or a sponsor lounge where the screen exists to look alive. Industry accounts, relevant news, your own posts mixed in. Nobody reads it closely, so density matters more than pace.
Pick one per screen. A wall trying to do all three does none of them, because the pacing that suits a queue is wrong for a corridor.
Curation, and why hashtag-only is a mistake
The instinct is to pull everything using the event hashtag. At a small event that produces a mostly empty screen. At a large one it produces a screen you cannot leave unattended, because open hashtags attract spam, and a conference hashtag with any reach will pick up crypto bots within the hour.
Following accounts rather than hashtags avoids both problems. Build the wall from your own account, your speakers, your sponsors, and a handful of relevant industry voices. You lose spontaneous attendee posts, which is a real cost for a participation wall, and you gain a screen that cannot embarrass you at 3pm on day two.
For a participation wall where attendee posts are the point, the workable middle ground is to follow the speakers and the official accounts, and have someone reposting the good attendee content from the event account. That puts a human between the open internet and your main stage.
Setting up the display
- Build the account list in the dashboard and save it as a group.
- Choose lanes based on the screen. One or two for a portrait display, four to six for a landscape TV, more only if the audience is close enough to read them.
- Set the display size to Large or XL. Wall text is read from three metres away, not from a desk.
- Generate a share link, then open that link on the machine driving the screen.
- Put the browser in full screen and disable sleep and screensaver on that machine.
The share link matters because the display machine will not be logged in to your account, and often should not be. It is frequently a borrowed laptop or a media player behind a screen that other people can reach.
Matching the room
Backdrop colour is worth thirty seconds of thought. Conference halls are usually dim, and a dark backdrop reads well and does not glare. Exhibition floors and hotel lobbies are bright, and a dark screen there reads as switched off.
You can set any colour with a parameter, which is the easiest way to match a sponsor palette without design work:

Things that go wrong on the day
Venue wifi. The wall needs a connection for the whole event, and conference wifi degrades exactly when the hall fills. If the screen matters, put it on a wired connection or a dedicated mobile hotspot rather than the guest network.
Machine sleep. The single most common failure. A laptop driving a wall will sleep on its default power settings and you will find a black screen after lunch. Change the setting before the event, not after.
Quiet periods. During keynotes nobody posts, so the wall goes still at the moment the most people can see it. Adding a few reliably active industry accounts keeps movement on screen through the gaps.
Nobody assigned to it. Someone should be able to see the wall from where they are working. Not monitoring it constantly, just close enough to notice if it freezes or shows something it should not.
Common questions
How many screens do we need?
One in a place people wait beats three nobody stands near. Registration queues, coffee areas, and the space outside the main room are worth more than a corridor.
Can we run different walls in different rooms?
Yes. Each group gets its own share link, so a track specific wall outside each room is just a separate account list and a separate URL.
What happens if a followed account posts something inappropriate?
It appears, which is the argument for following accounts you have chosen rather than an open hashtag. Removing a handle from the group takes effect on the next refresh, roughly thirty seconds.
Does it work on a hotel or venue screen we do not control?
If it has a browser or accepts an HDMI input from a laptop, yes. There is nothing to install, which is usually what makes it possible on borrowed hardware.
The short version
Decide what the screen is for, build the list from accounts rather than an open hashtag, size the text for the room, and check the power settings on whatever is driving it. The wall itself is ten minutes. Everything that makes it work happens before that.
