I use Catalina on Asus A550JX everything is OK but When i plug HDMI monitor before boot OS. It's can't boot and restart continuously.
Issue
I boot windows only. not plug HDMI monitor. everything OK.
If I connect HDMI monitor before boot OS. It's can't boot and restart.
I have to get into the OS first. After that, plug HDMI to laptop and monitor can use. everything OK.
I select Device > UseIntelHDMI already but not work.
