With recent sales of 5700G,
I upgrade the CPU from 3700X to 5900G so that I can free a bit of computation from the discrete graphics card while doing heavy GPU computation.

I upgraded the bios of b550m-itx/ac, and it works with video output when the discrete graphics card is disconnected. But it always produce video output on the ports of discrete graphics card after I put back the card. Some searches tell me that the discrete card has priority so I try to set the primary video adapter to "Int Graphics". Now all I get is black screen on all video ports.

I am not asking for enabling both GPUs, but rather just trying to get the video output from iGPU.
