Oh, that's a very common mistake, one that I still make myself every now and then when troubleshooting Ryzen CPU's. If the AMD processor has a G in the name, such as 2200G, 2400G, Athlon 240GE, etc, they have integrated graphics. Intel's normally have integrated graphics unless it has an F in the name, like Core i7 9700F, Core i9 9900KF, etc. Hopefully things go smoothly once you have a GPU connected. If not, let us know, we'll do what we can to help!
