New GPU isn't showing

[Terminator_]

Hey, I just got my new GPU, a Nitro+ RX 480 4GB, upgrading from a GTX750ti, I loaded up my PC, the lights and fans on the card are working, but my computer isn't showing it connected, and is using the Motherboard graphics.
Someone please help

Do you connected the monitor to your GPU?

Yeah, it sounds like you haven't hooked your screen up to your new GPU yet. No need for onboard anymore.

Everything's correctly connected, the display is working, and there is power going to the card

I even tried to switch back to the GTX 750ti, and it still works, so the motherboard isn't broken

Problem solved:
Turns out I had to get a new driver for it, and then set it up, finally works now.
