Can I select which GPU to use?

Hello, I am Richy.
I own the Oculus Rift S, and I have a question.

So, my desktop has 2 graphic cards; a AMD Radeon RX 580 8GB and also a NVIDIA GeForce GT 220.
I mainly use my RX 580 for graphic intensive processes like gaming and etcetera, but I use the GT 220 for my other monitor which is just for notes and other small stuff.
Whenever I launch the oculus app, The oculus app thinks that I will be using the GT 220 to connect my Rift S.
I looked around in settings, and couldn't really find anything to solve this, which basically forced me to take out my GT 220 every time I want to play VR.
If the answer to this would be something like "use the gt 220", I can't use the GT 220, because it has no DisplayPort and isn't powerful enough to handle a VR headset.
If there is a possible way to select the graphics card to use, can someone please tell me.

Thanks

    Are you starting the app with your Rift S already plugged in? Because it can only really use the card that it’s connected to. The presence of the other card might be confusing to app into giving you a message about your video drivers, but if you ignore that, does it actually prevent you from playing, or impact your game performance?

    Thats a pretty weird setup, though. Do you really need to keep such an outdated GPU in your system? Why not just plug your second monitor into your primary GPU?

    Hello, @nalex66

    No, I am not starting the app with the oculus already plugged in.

    If I ignore the video driver messages, then when I plug my Oculus DisplayPort cable into my RX 580, it just doesn't detect it. The Oculus App thinks that I am connecting my Rift S to the GT 220.

    I mean, Yes, I can remove the GT 220 and plug my second monitor into my main card, but the RX 580 has 3 DisplayPort outputs, 1 HDMI output, and 1 DVI output.
    That 1 HDMI output is being used by my main monitor, and I don't have a DisplayPort to HDMI cable for my second monitor.
    I know I have a DVI cable but I just can't seem to find it.

    I will try the solution where I plug the Oculus Rift S in before starting the app, and give an update if it works.

    Great news, I have found a solution to all this.
    Now I don't need to take out the GT 220 every time I want to play in VR.

    All I did was disable my GT 220 in Device Manager under properties.

    That will serve as a temporary solution whilst a DisplayPort to HDMI cable ships to my location.
