gpu passthrough Nvidia RTX 2060 all ok but no video signal

[fr23]

Hi, I got very easily with my old Amd radeon hd 7780 graphics card the passthrough gpu, but now I have a msi geforce rtx 2060 ventus gp oc and I do all the steps, the machine boots but does not give video signal. For my old card I had no problem. I am going to post my settings. I hope someone can help me, I am using a translator since I am Spanish and I have little base in English. Hope you can understand me.

Right now I am using proxmox 6.0.4, but I have tried 6.4 and version 7 without success. Please help

Checked that the machine starts correctly, I can access by remote desktop. I try to also try to pass it its own extracted rom. Nothing I follow without video signal

is there no one who can help me?

Rdp works and the vm detects the gpu correctly? What exactly do you mean by „no video signal“? Afaik using gpu passthrough results in a disabled vnc availability. Or do you intent to use a display attached to the gpu?
