What is casting?

Casting (sometimes called screencasting or screen mirroring) lets you show a browser tab, window, or your entire screen from your computer on one or more Fugo-connected displays - live, without uploading anything to your media library first.

Unlike most of Fugo's other content features, casting doesn't have its own library or management page. There's no list of past casts to browse; it's a live, in-the-moment action you start and stop from the Screens page itself, tied to whichever screen (or screens) you're currently looking at.

It's useful for moments where you want a screen to follow what you're doing right now rather than play your scheduled content, like:

  • Presenting slides in a meeting room

  • Reviewing a live dashboard or spreadsheet with a group

  • Sharing a planning board during a stand-up

Under the hood, casting works differently from the rest of Fugo. Your regular content (media, Design Studio slides, dashboards) is stored in Fugo and pushed out to screens on a schedule. Casting instead opens a direct, temporary connection between your computer and the screen - nothing is uploaded or saved, and the moment you stop sharing, the connection closes and the screen returns to whatever it was playing before.

☝️ Casting is video only. It doesn't include audio. Fugo's screens aren't yet able to process incoming audio from a cast, so if the tab or window you share has sound, only the picture will come through.


What you'll need

  • An active Fugo account with at least one paired screen. Start a 14-day free trial if you don't have one yet.

  • A desktop browser that supports screen sharing. Casting isn't available on mobile or tablets yet.

  • A plan that includes casting. Core and Enterprise plans support it, and how many screens you can cast to at once depends on your plan. Reach out to sales@fugo.ai if you're not sure what's included.


How to start a cast

Casting always starts from the browser's own sharing picker, not from Fugo directly. Fugo only tells your browser which screen(s) you want to send the picture to. This means your browser (not Fugo) controls exactly what gets shared, and you can stop sharing at any time from either side.

Cast to one screen

1. Go to your Screens page. Find the screen you want to cast to and click on its preview card.

2. In the screen's details panel, click the casting icon.

3. Your browser will open its own sharing picker - choose the tab, window, or entire screen you want to share, then click Share.

Your selected content starts mirroring to the screen right away.

Cast to multiple screens

1. Go to Screens and click Cast to screens in the toolbar.

2. In the Cast to screens window, select the screens you want to cast to.

3. Click Cast to [number] screens.

4. Choose what to share in your browser's picker, then click Share.

Fugo mirrors your selected content to every screen you chose, from the same browser tab or window - you don't need to repeat the sharing prompt per screen.

☝️ To keep playback smooth, casting is capped at 1920×1080 resolution and 15 frames per second. If you're sharing a 4K or Retina display, the screen may show black instead of mirroring your content - try sharing a standard HD window or tab instead.


Manage an active cast

When you start a cast, Fugo shows a "Casting to [number] screen(s)" panel with three actions: Stop casting, Change screens, and Hide.

If you click Hide, the panel gets out of your way but the cast keeps running - a small Casting status bar takes its place, pinned near the bottom of your screen. That status bar follows you anywhere in the Fugo CMS, not just the Screens page, so you're never more than a click away from your active cast:

  • Click Edit to change which screens you're casting to

  • Click Stop casting to end the cast

When you stop a cast from the status bar or the multi-screen cast window, Fugo asks you to confirm first, since stopping ends the cast on every screen at once:

Stop casting?
This will end the cast on every screen you're streaming to.

Choose Keep casting or Stop casting.

You'll also notice the cast reflected back on the Screens page itself: while a cast is active, the toolbar's Cast to screens button turns into a Stop casting button:

Casting also shows up from the other side: your browser. Whatever tab, window, or screen you chose to share gets its own sharing indicator straight from the browser with its own way to stop:

Closing the shared tab, or clicking that browser-level "Stop sharing" control, ends the cast immediately - same result as clicking Stop casting inside Fugo, just from the other end of the connection.

If your connection briefly drops mid-cast - a spotty Wi-Fi moment, for example - Fugo will automatically try to reconnect to the screen before giving up, so a short network hiccup usually won't mean starting your cast over.


Configure a casting link

Everything above assumes you're casting from inside Fugo, using your own account. But casting isn't limited to Fugo users - anyone in the room can cast to a screen too, without logging into Fugo or needing an account, using a casting link tied to that specific screen.

Each screen has its own casting settings, so you control whether this guest-casting option is available at all, and what it looks like when it is — useful if, say, a meeting room screen should let any guest cast using the on-screen link, while a back-office screen shouldn't invite casting from anyone.

To review them:

1. Go to your Screens page, select a screen. Click the Edit button to open its settings:

2. Then open the Casting tab.

From here, you can configure your casting settings:

Enable casting

This is the master switch for the screen. Turn it on to allow anyone with casting access to mirror their tab, window, or screen to this display; turn it off and the screen won't accept a cast at all, regardless of anyone's role permissions. Every other setting on this tab depends on this being on.

Display casting instructions

When this is on, the screen itself shows a short on-screen prompt explaining how to cast to it whenever no one is actively casting.

This is aimed at people in the room who want to cast but might not know how - a meeting room guest, for instance - so they don't need to track someone down to ask, or even log into Fugo at all, to cast to that screen themselves.

Instructions style, size, and positioning

These three settings control how the on-screen casting instructions look, so you can make them prominent or unobtrusive depending on the room:

  • Style - Popup or Bar. A popup is more attention-grabbing; a bar sits at the bottom of the screen.

  • Size - Big or Standard. Choose Big for a large meeting room where people need to read instructions from across the table.

  • Positioning - Static or Dynamic. Static keeps the instructions in one spot; Dynamic moves them periodically, which can help avoid burn-in on the display over long periods of idle time.

Here's what the pop up style looks like:

And here's what the bar style looks like:

Wi-Fi details

Optionally show a network name and password alongside the casting instructions, so a guest who isn't already on your network can join it and cast without needing to ask anyone. Leave this toggled off with the network is open, or if you'd rather guests get Wi-Fi details a different way.


Troubleshooting

The Cast button is disabled

Check whether you're on mobile or whether your plan includes casting first - these are the most common reasons.

I see an upgrade message

Your plan may not include casting, or you may be trying to cast to more screens than your plan allows - reach out to our team if you're not sure what's included.

The browser's sharing picker doesn't appear, or I cancelled it.

If you close or cancel the browser's sharing picker, Fugo simply won't start the cast- click Cast again to retry.

There's no audio

This is expected; casting is video only.

My 4K display shows a black screen instead of my content.

Casting is capped at 1920×1080 and 15fps. Try sharing a standard HD tab or window instead.

Firewall and network requirements

Casting works by opening a direct, peer-to-peer connection between your computer and the Fugo player on the screen, rather than routing your content through Fugo's servers. To make that direct connection possible even when one or both sides are behind a router or firewall, Fugo relies on a small set of third-party relay services to help the two sides find each other and, if needed, relay the connection.

If you're casting from a private, enterprise, or secure network - which is common for office Wi-Fi - a firewall or strict NAT policy can block this connection before it's established. If casting isn't working and you suspect this might be why, ask your IT team to allow outbound connections to:

  • stun.l.google.com and stun1-4.l.google.com, port 19302 (Google's public STUN service)

  • standard.relay.metered.ca, ports 80 and 443 (Fugo's TURN relay provider)

  • 0.peerjs.com, ports 3478 and 443 (the underlying peer connection service)

These are third-party relay services Fugo's casting feature depends on - not Fugo-hosted servers - so if your organization filters outbound traffic by destination, these are the domains that need an exception.

You can also refer here to Fugo's list of domains and ports to whitelist on your network if required by your organization.
