For 19.04, I am working on it because I found some strange issue with HDMI too after installing it.
Boot system connected with HDMI connected, first it shows only blank purple magenta and after a minute, only blank black screen. Power off the smart station, disconnected both HDMI, VGA, and boot the system and after completion of booting, connect the HDMI, it shows login screen. I will give you a log.
