My OBS Setting is for 2K HDR Settings...
Can't I use ndi plugin using HDR?

My current video setting is for HDR btw.

I'm streaming HDR in Youtube, and for SDR in Twitch.

My second computer is for SDR streaming and using NDI.

Can you help me?

I think the main thing is this thing.

To send signal with HDR the NDI plugin gives problems, like this one.

And if it manages to send something, it will be missing the tone mapping. You can try Teleport or Beam. These plugins usually work with HDR signals, but the tone mapping is missing.

There is another way...is to use NDI Tools 6.

You can do it in two ways, always using the Screen capture TX tool of NDI Tools 6 on the PC that broadcasts in HDR.

You have to select HEVC 10-bit in Screen capture TX for the tone mapping to be correct.

One would be to send the screen in HDR and on the receiving PC use the Studio Monitor of NDI Tools 6 and capture that screen in OBS.

Another way would be to use two monitors on your gaming PC. You disable HDR in Windows on the second monitor, where you put a full screen OBS projector.

In Screen capture TX you can send in HEVC or 264 (NVENC) because you will send in SDR. This signal is picked up by the OBS-NDI plug-in perfectly because it is in SDR.

Personally, I don't know how to send sound in these cases and I use Teleport to send sound (from the OBS desktop source with a filter) together with NDI to the other PC.
