I have two trial copies on 19.0.047 installed on two Windows 10 machines on the same network. On one machine, adding the NDI input to the mixer works fine. On the other, it doesn't. I am able to see the various preview windows correctly when I goto Add Input > NDI, but as soon as I add the selection as an input, it just shows up as black. Clicking the settings for that input shows it as a 32x32 size input, which it should not be. Any thoughts would be appreciated, thank you.

Have you verified that your network is running at Gigabit speed? Any firewalls in place? Or tried turning them off? Kane Peterson NewTek

I just installed the tool set and tried the monitor. I was able to view the feeds no problem with the NDI monitor, but it still does not work in Vmix. Any other suggestions?

The other machine is Xeon E3-1220 3.1 GHz with whatever the built-in graphics chipset on the board is. Both have 32GB of RAM. How detailed do you want the specs? Thank you!

Those suggestions did not help. Network is private, discoverable, no firewall, media sharing is on. The strange thing is the previews show fine under the add input options when I choose NDI - I see the whole array of choices just fine there. But as soon as I add the input to the mixer, it is black. I attached a pic of this above, but it didn't embed it probably due to its size. If you didn't see it, scroll up for the link to 2017-05-30_1154.png I also installed Vmix on my laptop and tested adding the same NDI feed there, and it worked fine. So the issue is definitely with just this one computer.

Note that you will definitely need to install a graphics card on the system, the built in server graphics is for basic console use and will not work with vMix properly, so you won't get far even if this issue is resolved unfortunately.

Now it's working fine. Consider this solved. Thanks for all the help. Definitely planning to buy vmix - it's been great so far.
