[ERROR] [Vdd] Unable to find display or encoder during startup

[univers629]

I used parsec-vdd to create a virtual display to connect the tablet as an extension screen. Sunshine works fine when I connect a virtual monitor using Intel CPU Core Graphics. When I wanted to use NVIDIA's discrete graphics card, I first switched to the laptop's discrete graphics direct connection mode. When I used mirroring mode to stream the screen to the tablet, sunshine worked without error, and the unexpected situation occurred as follows:

I used the "dxgi-info" tool to detect that the virtual display I created with parsec-vdd was connected to the nVidia graphics card, but sunshine would report an error after running it.

The following is the log from the sunshine side:

There are two related issues #844 #1612, that have run ddprobe.exe with zero exit code (error).
You can try it with ddprobe.exe is from the tools folder.

ddprobe [0] [\.\DISPLAY1] && echo %errorlevel%
9009   (success)

ddprobe [0] [\.\DISPLAY44] && echo %errorlevel%
0      (error)

I succeeded in non-discrete graphics direct connection mode. I changed the value of disablechange in the registry to 0, and then specified the virtual reality device to connect to the 10DE NVIDIA graphics card.
However, when streaming moonlight in direct connection mode, there will still be an error message of "Connection terminated, no video received from host, please check your firewall and port forwarding rules Ports in: UDP 47998 UDP 48000", a black screen, and no video received. But I don’t want to use the direct connection mode of the independent graphics, so I don’t care about it. 😉

A same problem to me after I install Gameviewer (a remote controller from Netease)
I figure it out by let the laptop using Nvida globally, and the ddprobe.exe still report with 0 (in CMD , i still can't find how to using && in WPS )but sunshine works fine.
I think might some software change some default setting, but I can't find where exactly.

by the way, the problem can't be solved by let sunshine.exe using Nvida, if someone know how to set, plz let me know, using Nvida globally is not a power-saving way for someone always keep PC on like me.
