I'm following this wiki guide (https://pve.proxmox.com/wiki/Pci_passthrough) for PCI passthrough for my RTX 2070 but getting black screen video when the VM starts (I'm directly plugged into the card HDMI output). I see the bios and grub but nothing after so I believe the device is not being touched by proxmox. When I connect with RDP I see that the device says error code 43 under device manager.
The weird thing is that this card worked perfect in my setup like 2 days ago for a brief test, so I know it works. I can also do passthrough consistently using a radeon R7 so I 100% know my bios is configured properly and the board supports passthrough. I'm losing my mind because everything seems correct from looking around.
Here's my config to hopefully help resolve the issue. Let me know if I can run anything else to narrow down the fault
/etc/default/grub
/etc/modprobe.d/iommu_unsafe_interrupts.conf
/etc/modprobe.d/blacklist.conf
output of lspci -n -s 1:00 (my 2070 address)
/etc/modprobe.d/vfio.conf
and finally /etc/pve/nodes/pve/qemu-server/101.conf (the vm I want to pass into)
