hdmi port keeps failing

My MacMini will randomly NOT recognize my HDMI port. Computer wakes... but monitor has no signal so automatically shuts down. Is there a way to check the HDMI port on my Mini? Sometimes when I unplug the port and plug back it, it resets, sometimes it doesn't.

I have a 2018 mini and have two monitors connected. One is connected by a DVI to thunderbolt cable and the other was connected to HDMI. The HDMI connection kept dropping, requiring frequent unplugging/plugging to get it recognized. I gave up and bought an adapter and now connect the HDMI cable through it to a thunderbolt port.


Now my usb port won't run an external camera. I've connected 2 different cameras, and they both freeze. Jeez.
