I am connecting a brand new Mac Mini (2020) via its HDMI (2.0) connector with a HDMI to DVI cable to an 1080p external monitor on Catalina 10.15.4.
The display shows a black screen and the only way to see the image is to disconnect the cable from either end (HDMI or the DVI) and connect it again once the computer is on (and the Mac OS welcome screen shows up) - then the image appears and all works fine (even in sleep mode - it awakes as it should showing the image again).
Is this a Catalina problem and is there a way to fix it or make it work?
I have tried resetting the SMC but nothing - the monitor works perfectly with my other older Macs so the problem is not there.
Thanks for your help
