So, just to close this out... it seems that the amdgpu driver had set an overly-restrictive maximum pixel clock if you used a DisplayPort-to-HDMI passive dongle. As per the issue I'm hopeful this will be fixed in a forthcoming kernel. Anyway, for now I am running a patched kernel and all of my monitors work fine with kernel 6.18.1.
