Hello, i read a lot about this issue but i cannot figure out to solve...
On Windows 2019 server, i installed Ultravnc 1.4.3.6 but when i connect using vncviewer i can see just a black screen.
- If i'm logged via RDP i can see the screen and works
- if i plug a display port cable, i can see the screen and works
- If i press ctrl alt delete, i can see Windows screen
Please let me know.

Black screen on Windows 2019 Server
Re: Black screen on Windows 2019 Server
Since i have an Nvidia Quadro P2200, i virtually connected the EDID of one monitor that i'm used to connect to this server, but my server run without monitor.
My question is : should Virtual Monitor installed be compatible with 2019 server ? Or is just for 10, 11 (client side) ?

The virtual monitor driver fix this and it should also be working on other versions then 10/11.
Server 2019 need to be at least 1903
