How to simulate a LED panel in Unreal Engine for accurate pixel mapping (non-realtime)?

Hi everyone,

I’m working on a project where I need to create content for a physical LED panel with a resolution of 4800x2400 pixels and physical dimensions of 18m x 9m. The content will be pre-rendered (not real-time), and I want to make sure that what I see in Unreal matches exactly what will appear on the LED — maintaining a true 1:1 pixel mapping.

My main question is:
What is the best way to simulate this screen in Unreal Engine so my camera sees the exact area for accurate framing and export?

I was wondering if nDisplay could help with this, but since I’m not running in real-time or across multiple displays, maybe it’s overkill.

Should I just create a surface with the correct aspect ratio and resolution, and manually match the camera to that? Or is there a better/more precise method for this kind of setup?

Any advice is greatly appreciated!

Thanks in advance!
