Can't get GPU pass through to work as I need!

[Nedio Server Unraid]

Hello everyone!

 

New to unraid and loving it so far. But I can't get the video pass through working as I need 

Below is my setup.

 

Hardware:

• Motherboard: ASUS Prime Z690-P WiFi Intel® Z690 (LGA 1700)
• CPU: Intel® Core™ i7-12700K Processor
• External GPU: ASUS Turbo GeForce® GTX 1080Ti 11GB GDDR5X
• (An old LCD) Monitor connected to External GPU via Display Port to DVI port cable (I Know my monitor is long overdue, will replace it at some point but a bit later)

 

Software:

• Unraid v6.11.5 with an XFS-encrypted data array
• Windows 10 VM (with auto start and with the External GPU passed through to it)

 

What I want:

• Use the VM as a day-to-day PC
• Shutdown my server nearly every day (it is in my bedroom and is annoying if working at night)
• Upon power-on get to the VM (on my monitor) with minimum hassle (need to figure out how to do encrypted array auto-start with the passphrase feeding without compromising the purpose of encryption).

 

My problem:

• Upon power-on Unraid "captures" the Graphics card where the monitor is connected... I can't force it to always stick to the iGPU and leave the External GPU for the Windows VM.

 

Workaround that works:

• attach the monitor to iGPU
• boot unraid (boot logs showing on the monitor) and start array
• disconnect monitor from iGPU and connect to the external Graphics Card - it works (displays the VM welcome screen)

 

The workaround is a no-go for me... Please help me understanding what am I missing.

If you can't fix it by changing some options in bios, what about buying a hdmi dummy plug and attaching it to the igpu?

If you have a second monitor, or you have a friend with a monitor, you can try to attach one to igpu and one to the gpu passed to the vm, if it will work, it will work with the dummy plug too.
