PC built but no display

Hi,

It is my first time building a pc so I'm not well versed in this area, but I believe I built everything accordingly. I plugged in connections and checked compatibility for parts, and when turning on power everything including my motherboard, gpu, cooler, and usb accessories (like my keyboard) get powered. However, when I connect my monitor to my pc there is no signal. I tried other monitors, cables, and both work with other devices. I tried unplugging my gpu and tried my integrated onboard gpu, and yes I have plugged my hdmi/dp cable to the corresponding ports. Is there a reason there is no connection between the monitor and pc? Also, I only have space for 2 ram and both are being used.

Parts:
CPU Intel 9 - 9900k
GPU Gtx geforce tuf 1650 super
RAM Corsair 2 x 8 GB 3200MHz
SSD Corsair MP510 480GB
Motherboard Z3901 AORUS Pro WIFI Mini ITX ( I ordered the wrong one but it is still compatible lol)
PSU Corsair CX550
Cooler Corsair H60


I know this question is everywhere but I have yet to find a solution
Please help!
