# nDisplay Setup

## nDisplay Configuration

Create your nDisplay configuration with the appropriate render node(s) for your hardware setup. For more information please check out the related documentation from Epic, [nDisplay Quick Start](https://dev.epicgames.com/documentation/en-us/unreal-engine/ndisplay-quick-start-for-unreal-engine)

1. Add an ICVFX camera component in your nDisplay setup if you haven't already<br>

## LiveLink setup for the nDisplay Nodes

Assuming you have the nDisplay configuration ready and you have added it in your desired level, there are 2 more steps before you can launch the nDisplay nodes

#### Step 1:

Connect the CameraTwin source via LiveLink and save the LiveLink setup as preset&#x20;

{% hint style="warning" %}
You will need to update the LiveLink preset on each session, since it's not serialized properly right now.  [Changelog Known Issues](/cameratwin/installation/installation-unreal-engine/changelog.md#known-issues)
{% endhint %}

#### Step 2:

In Project Settings under the LiveLink category you can find the "Default Live Link Preset"—set this to your preset. This will automatically activate the preset during the launch of nDisplay nodes

{% hint style="info" %}
We recommend to perform a quick test of the nDisplay setup using the nDisplay Launch to first ensure that the configuration is working on the same machine.
{% endhint %}

{% hint style="info" %}
Please make sure that all rendering nodes are within the same network and the the CameraTwin Soruce is reachable from all nDisplay nodes.
