I have a 2018 Mac mini and have problems waking it up from sleep. It was significantly worse when using the HDMI port on the Mac mini, I would get snow on the external display. Switching to USB-C eliminated the snow, but it still takes a long time for the monitor to receive the signal when waking up.

I have a 2011 MacBook Pro and had no problems on the same monitor.
