If I have a Ryzen processor with no integrated GPU, what happens when I connect a monitor to an HDMI port on the motherboard? Is the dedicated GPU from the PCI-E slot handling those? What happens if I take it out of the system? Does that mean I just get no video output whatsoever, or I do but it is the CPU doing all the work, making it unsuitable for anything graphics-intensive?

@cirno IIRC It shouldnt work if your CPU doesn't have any way to output video with GPU without GPU

@cirno You most certainly need an APU (CPU with GPU onboard).
