# Big screen: run the venue's screens from the console

> Pair the venue's screens and projectors with a code, then choose what each one shows: the join QR, a countdown, polls, Spotlight, media, Fan cam and more.

Big screen turns any screen or projector at the venue into part of the show. You pair each screen once with a code, then pick what it shows from the console, and change it during the event with one tap.

## Pair a screen

**1. Open the screen page**

On the computer that drives the screen or projector, open `luce.show/screen`.

**2. Type the code**

Type the pairing code shown in the console's Big screen mode. Or choose **Copy the link** in the console and open that link on the screen's computer.

**3. Name it**

The screen appears in the console's **Screens** list. Rename it (for example "Main stage" or "Bar") so you can tell them apart.

Choose **Pair a screen** to add more. Removing a screen sends it back to the pairing code.

## Sources

A source is what a screen shows. Pick one, check it in the preview, and choose **Set live** to put it on the selected screen, or on **All screens**.

| Source | What it shows |
| - | - |
| **Join QR** | A code guests scan to open the event page. |
| **Countdown** | A countdown to the event's start, to a time, or for some minutes, with an optional line above it. |
| **Message** | A line of your own, such as "Phones up for the finale!". |
| **Media** | One picture or video, or several as a slideshow. Big screen files are 16:9 and never reach guests' phones. |
| **Sponsor ads** | Your sponsors' square ads, in the order set in [Sponsors](https://docs.luce.show/modes/sponsors.md). |
| **Poll** | A poll from your reels, with live results. |
| **Spotlight** | Guests' Spotlight photos, as a slide or a grid. |
| **Now / Next** | The current and next parts from the [Agenda](https://docs.luce.show/modes/agenda.md). |
| **Phones lit** | How many phones are in the show now. |
| **Light mirror** | The colour the phones show. |
| **Fan cam** | The guest whose camera is on air. See [Fan cam](https://docs.luce.show/modes/fan-cam.md). |
| **Blank** | Nothing on the screen. |

Some sources let you choose a background: dark, the event's cover photo, or a colour.

## A screen facing the stage

A screen can face the stage instead of the audience. In the screen's settings, set it to face the stage, and it shows the [Timekeeper](https://docs.luce.show/modes/timekeeper.md): the speaker's clock and prompts.
