mac mini no dosplay

Hi all. My Mac mini and monitor doesn’t communicate with each other all of a sudden. Same Mac mini, same monitor. Just doesn’t display anymore. Blank screen.

The Mac mini can be re-boot smoothly, without any funny sound or heat problem as fast as I ‘feel’. I then connect the monitor with other computer, the monitor works as usual. May I know what can I do now? Since I can’t fix the Mac mini without a display.

Mac Mini blanks out randomly for a few seconds and then comes back on I have a new Mac Mini 2022, paired with a new HP M27FQ monitor. Installed with all the defaults, the monitor will go blank for a few seconds and then the screen contents will reappear. Occurs randomly. Cannot see anything in the logs. Tried changing the default display settings without much effect. How can I determine if my monitor is compatible with the Mac mini? Is there a list of compatible monitors?

Mac Mini blank screen at start up (after 10.14.6 upgrade) Since upgrading to OS X 10.14.6, my screen at start up becomes blank. This occurs only when you start your computer from power off. The only solution is to unplug and plug the HDMI cable (after logging in blindly). It doesn't occur after restart. If you restart (from menu) there is no blank screen. This is pretty annoying, and I believe it is a software issue, rather than graphic card problem. I plug in to another monitor with a different HDMI cable to see if this is due to the monitor or HDMI cable fault, but the issue remains. The signal was transmitted from the computer to the monitor, but it is just totally blank (black screen). My Mac Mini is 2018 model and has warranty up to the end of 2021. Any one experiencing this problem? If so, I can I let Apple knows of this issue (as I believe it is related to the OS X 10.14.6 (since it occurs on the first start up after the upgrade).
