Mac mini 2018 and Samsung C43J890 issue

I purchased an ultra wide monitor recently but display nothing when new boot of Mac mini. I suspected Samsung delivered USB-C cable problem and replace by Apple Thunderbolt 3 (0.8m). Problem still.

Sometimes I have to unplug cable and replug such that Samsung monitor could recognise "signal" from Mac, or reboot Mac again.

Anyone have this problem and solution?

Mac mini 2018 or later

Go to the Samsung Displays built in Menu and check to make sure that it is, setup and locked onto the input coming from your Mac Mini.
