DaVinci Resolve colour management for NDI output
The VDO NDI Output plugin does not grade or colour-convert your footage. It takes whatever pixels the timeline hands it, tags them with NDI® metadata, and sends them on the wire. That means the most important thing you can do for correct colour over NDI is to get Resolve's colour management set up right — the plugin's Input Primaries and Transfer Function settings should describe what Resolve is already producing, not change it.
This page explains how the four colour management modes in DaVinci Resolve feed the plugin, and which settings you should pick for common SDR and HDR deliverables.

The one-line rule
Whatever colour space and transfer function your timeline output is encoded in is what the plugin receives. Set the plugin's Input Primaries, Transfer Function, and Output Range to match the timeline output. Everything else (Content Type, Send NDI Metadata) is metadata that tells the receiver how to interpret the signal — it does not change a single pixel.
Where to find the timeline output colour space depends on your colour management mode. Open Project Settings → Color Management and look at the field named in the sections below.
Mode 1 — DaVinci YRGB (unmanaged)
