I am adding more monitors to my display configuration, and have depleted all my ports on my graphics card. I have tried to use a HDMI port on my motherboard, however my PC does not detect the new display or send a video output to it through the motherboard video port. My CPU does not have integrated graphics, and I could not find a setting in my BIOS to force a video output
Is it possible to use motherboard video ports with CPU without integrated graphics? If not, why?
I have ruled out problems with the monitor and cables by successfully testing the monitor with the video ports on my graphics card.
My current relevant specs, although this section is intentionally ambiguous to help others with a similar question and different hardware.
Motherboard: B450 Tomahawk
CPU: Ryzen 5 3600 @ stock
GPU: Nvidia GTX 1050 Ti
A similar question asked about forwarding GPU rendered graphics, but did not feature a situation that lacked integrated graphics.
