When I restart my 2018 Mac mini sometimes the Samsung CF391 32" monitor won't work properly. Let me explain I press the power button and the Apple logo and progress bar shows up on the monitor. Then the monitor goes off and has the flashing blue light like it's on standby as if the computer was off. The mini has the normal solid white light. I was forcing shutdown to fix this but now I realized if I unplug the HDMI cable from the mini and plug it back in the monitor turns on. It doesn't happen every time but maybe half the time. Is this something wrong with my monitor, my mini is glitching, or maybe a software problem?
