It could be that either you need a Driver from NVidia's Website (NVidia supporting FreeBSD, is quite a shock to me, given how proprietary they seem to be), or your particular GPU model isn't supported. You could alternatively make a Linux USB and test it there, to rule out any cross-platform issues, if they are indeed there. This could also help in determining if your GPU is bad or not. Also, nice Profile Pic! And welcome to the world of BSD.FreeBSD 12.0 When I watch a video through VLC on TV, I see a black screen, but audio work good. On the monitor, the video shows normal. What is the problem? TV connected via HDMI. Video card nvidia.
Which driver are you using? This is, in essence, a dual-monitor set up and that only works if you use the x11/nvidia-driver (or one of the other 'legacy' versions).Video card nvidia.

I wasn't sure about that actually. And it doesn't hurt to verify.Obviously, sound only works with the official blob.
