It looks like it is one of my monitors. I mean, it could theoretically be the dock... but I'm pretty sure I've isolated it.
My left monitor won't actually display anything now. I replaced the cable assuming that was the problem but I can't get anything to show on it now via the dock. The right monitor displays fine.
I swapped the connectors and the left monitor still won't display but the right one will. I also swapped the adapter (HDMI -> USB-C, HDMI -> DP) and still the monitor on the left doesn't display. Occasionally it will flash black and then OSD HDMI1 No input. I moved the cable to HDMI2 but get the same result.
The thing is, I can plug my Xbox into the monitor and it works as expected.
I can't verify the settings for the monitor's resolution and refresh rate because macOS thinks the monitor is working and is displaying the settings on the monitor that is black to me.
