Does the virtual display not support connecting to a laptop's discrete graphics card with direct-connect mode turned on, but only supports connecting to the core graphics card of the CPU? about parsec-vdd

ParsecVDD v0.45 has introduced an ability to set the parent GPU, check out this official guide.

我成功了，我是**🤣，上次用这个网页里的方法的时候没有发现注册表里有一项disablechange的值，把它改为0就好了，不过在独显直连模式串流moonlight还是会有“Connection terminated, no video received from host, please check your firewall and port forwarding rules Ports in: UDP 47998 UDP 48000”的报错，黑屏接收不到画面，不过我不咋用独显直连模式，就不管这个了😉

Thank you very much for your reply. I found that my virtual monitor was able to connect to the Nvidia discrete graphics card, but I found a new problem. If you have time and are interested, you can take a look:LizardByte/Sunshine#2417

Yeah I see, it could be a problem of vdd, but let's wait for response from Sunshine.

是的，我明白了，这可能是 vdd 的问题，但让我们等待 Sunshine 的回复。

Sunshine的回复似乎没有作用，我用ddprobe.exe测试确实得到了0的结果，我不明白nomi-san想表达什么，看起来似乎vdd事实上并没有连接到独立显卡，因为在nvidia的控制面板里只显示连接了一个笔记本的便捷显示屏😥
