PC NDI source detected but no streaming is received


New Member
My PC can detect my laptop and iPad NDI sources, but not showing anything (blank).
But my laptop can detect and receive and showing the stream from PC and iPad.

Both are OBS 27.0.1 (64 bit) and OBS-NDI 4.9.0.
I checked the Windows Defender Firewall, OBS is allowed to communicate via private and public networks.

Are there any other settings I should check? Thanks!
