# Customer Display

> Show order details to guests on a second screen

Go to **Setting → Customer Display** to configure a second screen that shows guests their order details as items are added.

## Display modes

<CardGroup cols={2}>
  <Card title="Same Device" icon="desktop">
    Opens on a secondary monitor connected directly to this machine (e.g. a dual-monitor counter setup).
  </Card>

  <Card title="External Device" icon="tablet-smartphone">
    Uses a separate tablet or screen, connected over WebSocket — useful when the guest-facing screen is a different physical device.
  </Card>
</CardGroup>

## Setting up Same Device mode

1. Select **Same Device**.
2. Under **Monitor**, choose which connected display to use — **Auto-detect (secondary monitor)** works for most setups, or manually select a specific monitor if you have more than two connected.
3. Tap **Launch Display**.

The customer-facing screen opens on the selected monitor, showing live order details as you add items.

## Setting up External Device mode

1. Select **External Device**.
2. On the *other* device (the one facing the customer), connect it as a customer display terminal using this device's connection details — check **Connection & Terminals** for the address to use.
3. Once connected, order details push to that device automatically in real time.

<Tip>
  External Device mode is useful for tableside ordering setups, or when your checkout counter doesn't have room for a second physical monitor.
</Tip>

<Note>
  The customer display is read-only for guests — they see the order and total but can't make changes from that screen.
