Hello Proxmox Community,

I'm seeking assistance with configuring GPU passthrough on my MINIS FORUM Mini PC NAB6 running Proxmox VE. Here are the hardware details:
  • MINIS FORUM Mini PC NAB6
    • Processor: Intel Core i7-12650H up to 4.7 GHz
    • RAM: 32 GB DDR4
    • Storage: 1 TB PCIe 4.0 SSD
    • Networking: Dual LAN, WiFi 6, Bluetooth 5.2
    • Graphics: Intel UHD Graphics 770 / Alder Lake GT1
    • Ports: 2 x HDMI, 3 x USB Type-C, 4 x USB Type-A
I have successfully identified the GPU in my system using the following command:

Code: 
root@pve:~# ./foundIOOMU.sh
IOMMU Group 0
00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P GT1 [UHD Graphics] (rev 0c)

Additionally, I have confirmed that the IOMMU feature is enabled in the system:

root@pve:~# dmesg | grep -e DMAR -e IOMMU

However, despite these confirmations, I am encountering difficulties in passing through the GPU to a Windows 11 VM.

I would greatly appreciate any assistance or guidance on how to properly configure GPU passthrough for my setup.

Thank you in advance for your help!

if u know how fix this problem please
 
Have you tried enabling PCI-Express in Edit PCI Device advanced settings?

6.146403.png

Try enabling that and then setting the Display to None.

Then you should get output on your attached display.
