Just made this new PC and the HDMI port does not show my second monitor.

asus x570 plus (wifi)

I have tried multiple cables. Cables work if I plug the HDMI into the gpu but I cannot get the MOBO hdmi to work.

Any suggestions or things I could look at to fix this?

you don't plug anything into the mobo, that is for integrated graphics only. you should only be using the gpu connections unless you have an APU instead of a GPU.

Ahhh I see. Last processor I owned had integrated graphics. Thank you for the response.
