<div dir="ltr">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.</div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jan 18, 2017 at 1:45 PM, Will Marler <span dir="ltr"><<a href="mailto:will@wmarler.com" target="_blank">will@wmarler.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">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.</div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jan 18, 2017 at 12:19 PM, Jayme Howard <span dir="ltr"><<a href="mailto:g.prime@gmail.com" target="_blank">g.prime@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">I've used both together, but I don't remember if one was mirroring the other or if I did it as dual-monitor.
