Put Your Logo on Your Displays

This article explains how a logo gets from your computer onto a screen: where you upload it, how you pick which logo each display shows, and which logo wins when more than one is set. If you are only looking for the file rules, they are short — any image file, under 2 MB.

Your logos live in a library, not in a single slot

LobbyFlight does not have one logo slot per hotel. It has a logo library: as many named logos as you like, one of them marked as the default. You find it in the sidebar under Logos (owners and managers see this entry). Each logo is a tile with its name, a line telling you whether it is in use, and the actions for renaming, making it the default, and deleting it.

There is a second, older place a logo can sit: the hotel logo you upload in step 4 of the setup wizard under Portal → Setup. That one belongs to the property itself rather than to the library, and it acts as the fallback for every screen that has not been given a logo of its own. Both are described below, and the section on the priority chain explains how they relate.

What the file has to be

Only two things are actually checked, both in the browser and again on the server:

It has to be an image. The file picker is set to accept any image type, and the check is simply whether the browser reports the file as an image. PNG, JPG and SVG are the obvious choices, but GIF, WebP, AVIF and anything else the browser recognises as an image will pass. The hint under the upload area reads "PNG, JPG, SVG up to 2MB" — that is a recommendation, not the rule the code enforces.

It has to be under 2 MB. This is a hard limit. A file of exactly 2 MB or more is rejected before it is ever sent.

Nothing else is inspected. There is no minimum resolution, no DPI check and no required aspect ratio, so you do not need to prepare the file to a specific pixel size. The file is stored exactly as you uploaded it — nothing is converted, recompressed or flattened.

What does matter is the box the logo has to fit into. On a TV-sized display the logo sits in a 120 × 60 pixel area in the header, scaled down proportionally so nothing is cropped or stretched. In responsive mode the same box shrinks to 60 × 30 pixels on a phone and 80 × 40 on a tablet. A logo that is roughly twice as wide as it is tall therefore fills the space best, and a logo with a lot of fine detail or small lettering will be hard to read at that size no matter how large the file is.

Uploading a logo into the library

Open Logos in the sidebar. If you have not uploaded anything yet, you will see an empty state that says "No logo yet" — clicking it opens the same dialog as the button.

Click Upload logo at the top right. A dialog titled Upload Logo opens.

Click the dashed area marked Click to upload and pick your file. This area responds to clicks only; dragging a file onto it does nothing. (The one drop zone in the portal is the organization's default logo, further down.)

The file is checked the moment you select it. If it passes, a preview appears and the logo name is pre-filled from the file name. If it fails, you get the reason instead — see the troubleshooting section below.

Give the logo a name you will recognise later ("Main logo", "Reception, white version") and click Upload. The button stays disabled until both a file and a name are present, so nothing is saved by accident.

Your first logo automatically becomes the default. Every logo after that is simply added to the library — it does not replace anything, and it does not appear on any screen until you assign it.

Check the logo against the background it will land on

A logo you cannot see on a dark board looks perfect on a white guest page, and vice versa. That is what the toggle at the top of the library is for. It appears as soon as you have at least one logo and switches every tile preview between two backgrounds:

On the board shows your logo on the near-black background the flight boards run on.

On the guest page shows it on white.

This is the practical test for whether a logo needs a transparent background or a version with a light outline. Look at both before you assign a logo to a screen.

Choosing which logo a display shows

Each screen decides for itself. Open Displays, open the screen you want, go to the Appearance tab and find the Display Logo section. Under Logo comes from you pick one of three mutually exclusive options:

From Logo Library lets you pick one of your library logos from the row of tiles below. This option is locked until the library has at least one logo.

Custom Logo for this Display uploads a file that belongs to this screen alone and never enters the library. The same two rules apply: an image, under 2 MB.

No Logo shows the hotel name without any logo at all and suppresses every fallback described below.

A Manage Logos link next to the section heading takes you straight to the library. Like everything else in the display editor, your choice is only stored when you save it in the editor's save bar.

Which logo a screen ends up with

When a display asks for its configuration, the logo is resolved in this order, and the first match wins:

A custom logo uploaded for that display.

The library logo selected for that display.

The effective branding logo — your property's own hotel logo if it has one, otherwise the organization's default logo.

The library's default logo.

Two things override this. If the display is set to No Logo, the chain stops immediately and no fallback is used. And if your organization has Lock branding switched on, the display-level choices in steps 1 and 2 are skipped entirely and the organization's logo is used instead.

If a screen shows a logo you did not expect, walk down this list — it is almost always step 3 or 4 quietly filling in for a screen that was never given a logo of its own.

Organization-wide branding

If you run several properties, open Organization → Branding. The Default logo there applies to every property that has not set a logo of its own — this is the one upload area in the portal that accepts drag and drop as well as clicking. The Lock branding switch makes the organization's brand win everywhere: property branding becomes read-only and per-display logo overrides are ignored.

Renaming, promoting and deleting logos

The actions sit permanently in the footer of each tile — there is nothing to hover for. The star makes a logo the default, the pencil turns the name into an editable field, and the trash icon deletes it. The line above them tells you the state of that logo: whether it is the default, and either "on N displays" or "not in use".

Deleting asks for confirmation first, and the question changes depending on whether the logo is live. For an unused logo it simply asks whether to delete it by name. For a logo that is in use it names the number of screens affected and tells you they will fall back to the hotel logo — which is exactly what happens: the reference is cleared from every one of those displays, and they resolve their logo again from step 3 of the chain above.

Two more consequences worth knowing. Deleting removes the stored image as well as the database entry, so it cannot be undone — you would have to upload the file again. And if you delete the logo that was marked as default, one of the remaining logos is promoted to default automatically, so the library never ends up without one.

How quickly a change reaches the screen

Displays fetch their configuration every 20 seconds on their own. Nobody has to walk over to the screen, press a key or clear a browser cache — assign a logo, save, and within about half a minute the screen picks it up.

Flight data is on a separate schedule that depends on your plan: hourly on Basic, every 30 minutes on Pro, every 5 minutes on Premium. That cadence has no bearing on how fast a logo change appears.

Seeing it before you walk to the lobby

The preview lives with the screen it belongs to: Displays → open the display → Preview & URL. There you get a live preview of that screen, the display URL to copy or Open in a new tab, and a QR code encoding that screen's URL, which you can download as an SVG. Scanning it with a phone is the quickest way to see the header, and therefore the logo, on a real device.

One caveat: an inactive display shows no live preview. The tab tells you so — "Activate this display to see the live preview" — because inactive displays deliberately make no API calls, which protects your quota.

When the upload is rejected

"Please select an image file" means the browser did not identify your file as an image. This usually happens with PDFs, EPS files or Illustrator and Photoshop documents. Export the artwork as PNG or SVG and try again.

"File size must be less than 2MB" means exactly that. For a photographic logo, save it as a JPG at a moderate quality setting; for a flat logo with few colours, PNG or SVG will usually be far below the limit already. Since nothing in the product cares about pixel dimensions, scaling the image down is a perfectly good way to get under 2 MB.

If you ever see the wording "File must be an image", that message came from the API rather than the portal — in normal use the file is stopped in the browser before the request goes out.

What it costs

Nothing extra. Logo upload and the rest of the branding options are part of every plan — Basic, Pro and Premium alike.

Next steps

Customize Colors and Use Themes — set the primary and secondary colors your logo will sit next to.

The display editor — the rest of the Appearance tab and how the save bar works.

Several properties — organization-wide branding and what locking it does.

More than one screen — giving each screen its own look without repeating yourself.
