Running into a weird issue with NDI, I am outputting from vMix my main output, but when I go to the NewTek Studio monitor, it shows the output as "vMix output 1" on the computer, but when I select it, it is just a black screen. I have tried low bandwidth mode, and a total reboot of the computer (laptop receiving it). Its weird that it shows it is seeing the NDI output, but the screen is black.


On local vMix PC, the NewTek studio monitor shows the NDI feed properly.

Make sure the remote host conforms to the specs requirements for NDI
Make sure both computers are the same network
Make sure there is no firewall issue
etc...

Dig this forum as well as Newtek's for more solutions about this common error

Both firewalls are turned off, same network, can ping the other PC, requirements are met and exceeded for both PC's.

Check Newtek stuff versions...
Does the computer with NDI Monitor gets any NDI signal to play ? I feel like it is not a vMix issue here... To be confirmed...

Right now I only have the one NDI coming out of the computer. You may very well be right, it may not be a vMix issue here, just not sure where else to look.

What is the network between these systems? Have you verified they are gigabit? And I don't mean, "I'm using gigabit gear", but that you have double checked that it is actually running at gigabit speeds.

If you are seeing NDI sources to select, then NDI discovery is working, but something is happening that is preventing the signal from making it thru or the latency is too high on your network and the packets aren't arriving in time.

I believe its a 10/100 NIC on the recieving computer, that would do it. Shame vMix doesn't support NDI HX Transmit rates.

NDI|HX is for hardware devices. Gigabit as a minimum is not asking much for a system to be used in live video production.

Agreed, Gigabit is normal these days, I was in an older building with 10/100 switches, so that was my limiting factor.

Thanks for the assistance! Will hopefully get a dedicated gigabit line for this use in the future.
