Question Using one GPU to play a game while outputting from another


Apr 13, 2014
So I got my self in a weird situation. I just purchased a used GTX 570 (it works fine, tested it on seller's system) and found out I actually don't have the cable to connect it to my monitor.

I've already ordered one, but it will take about a week or so to arrive and I need a more immediate solution.

Now I have the 570 on the first PCIe slot, and my crappy 220 on the second one, configured it so I get an output from the second slot and basically I can use my computer like normally.

Except the 570 is a ghost. The driver doesn't see it, windows doesn't see it. GPU-Z sees it as a basic display adapter, but with the normal hardware of the 570.

I'd like to know if there is a way to play games, like render them on the 570 and pass the output to the 220 so I can see what I do on the monitor.

I've done it myself in the past, passing a dedicated gpu output from a motherboard onboard graphics slot, but I don't have any onboard graphics at the moment and I can't seem to find a way to do this with 2 dedicated GPUs on the internet.
