Yes, I can confirm that a PC with on-board Intel card and an NV card can be
configured for dual-monitor, with Aero on. And I can make a video window across
both screen.However, I haven't success with Linux host. I've read in another
thread that you can start 2 X server, each for one card.
While for VM, the qemu pass-through readme said IGD card can be the secondary
card for calculation only (so no output). This mode is named "Universal
Pass-Through", so maybe the NV card in this mode will have the same behavior?

It just treats them as independent displays. It can either mirror them, or
extend the desktop onto multiple. It can't do multiple independent desktops.
A real life example of this is a motherboard with onboard video coupled with a
discrete GPU in a slot. As long as the onboard isn't disabled, they can work
in tandem, at least for software rendering. From what I understand, as well,
DirectX 12 and Vulkan both support hardware rendering with multiple GPUs of
different brands.

That's an interesting scenario ... How does Windows handle multiple graphics
cards? Like, let's say this was all bare metal, and the machine had 2 different
models of nVidia cards and an ATI card, with a monitor connected to each card.
Would Windows be able to display a desktop on each monitor, or span a single
contiguous desktop across them? If yes then I'd guess that what you're asking
is at least theoretically possible, though I've never tested personally.

I've used both together, but I don't remember if one was mirroring the other or
if I did it as dual-monitor. It was a configuration I abandoned early on. It
DID work, but it caused (about 75% of the time) Nvidia code 43 issues for me.
But it definitely did work outside of that.

Is it possible for a guest VM to use both spice server graphics with
qxl video AND hdmi gpu passthrough? Could the guest be configured
(windows 10 in this case) see it as a dual-monitor setup?
Has anyone tried this or gotten it to work?
