I am working on a newly assembled computer, and I am afraid I might have not plugged something in right.

Motherboard: TUF Gaming B650E-E Wifi

Graphics card: AMD Radeon RX 9060 XT

Case: Phanteks XT Pro

PSU: Corsair RM750e

The graphics card does light up so it's getting some power.

Neither the DisplayPort nor the HDMI cable works for the graphics card.

I tried unplugging each thing (monitor and computer) to powercycle as that is supposedly the usual answer to my problem.

The DisplayPort on the motherboard works, is that equivalent to the others?
