2022 Big Sur 11.4 (20F71) on Mac Mini no longer recognizes dual monitors?

I have to use one that HDMI to HDMI and one thats USBC to HDMI

The HDMI to HDMI one doesn't show up


I've opened the system preferences and the one that is USBC to HDMI shows up correctly as and LG HDR 4k but not the other same brand and model that's HDMI to HDMI


Option (detect displays) does nothing

I see this issue going back two years on mac minis


Mac mini, macOS 11.4
