# Perform

## Dual Monitor & Projector Setup

Nodalin supports external displays for live performances, presentations, and dual-monitor workflows. Send your visuals to a projector or second monitor while keeping the editor on your primary screen. 

### Quick Start

1. Click the **External Display button** <i class="fa-tv">:tv:</i> in the Render View<br>

2. Drag the new window to your external display or projector
3. Click the **Fullscreen button** (⛶) in the external window
4. Click **"Got it, Proceed"** in the confirmation dialog

<div data-with-frame="true"><figure><img src="https://937151318-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F44MuVIHBk5o5yfcGn64w%2Fuploads%2FME9cHeMWLKRVXeCz1lyF%2Fimage.png?alt=media&amp;token=30f355d2-965e-4601-8202-8f763efb9015" alt=""><figcaption></figcaption></figure></div>

The canvas switches to your display's native resolution automatically.

Closing the external window returns the canvas to the editor.
{% endhint %}

### Best Practices

1. **Set aspect ratio first** (16:9 for projectors, 9:16 for vertical displays)
2. **Move window to target display** before going fullscreen
3. **Avoid overlapping** the external window with the editor (causes rendering to pause)
4. **Use desktop app** (to be announced) for better multi-monitor support (no popup blockers)

{% hint style="warning" %}
**Note:** Browsers automatically pause rendering in background or overlapped windows for security and performance. If the external display overlaps the editor, or the editor is minimised — rendering will stop. Always move the external window to a separate display or ensure windows don't overlap.
{% endhint %}

### Troubleshooting

**External window won't open:**

* Allow popups in browser settings
* Use the desktop app (to be announced)

**Rendering stops:**

* Don't overlap windows
* Don't mimize the Editor window
* Move external window to a different physical display

**Exit fullscreen:**

* Press `Esc` key
* Click the fullscreen button (⛶)
