P2412H, Mac mini M1, not waking up?
I use Mac mini M1 with two Dell monitors. 23' and 24''. 23" is working fine. But my 24" P2412H goes to sleep mode and does not awake anymore. I keep pressing the power button two times for "off" and "on". But it displays and instantly goes black again. After a few 10-12 minutes later it automatically turns on. Also, If I turn off that Mac mini M1 and after if I try to on it on, but goes black. Please help. I hope I explain my question well.

Hello! It sounds like you're experiencing issues with your Dell P2412H monitor not waking up properly when connected to your Mac mini M1. Here are a few things you can try to troubleshoot the issue:
Check the connection: Make sure the connection between the monitor and the Mac mini M1 is secure. You can try unplugging and re-plugging the cables to ensure a good connection.
Update the monitor firmware: Check if there's a firmware update available for your P2412H monitor on the Dell website. Updating the firmware might help resolve any compatibility issues with your Mac mini M1.
Adjust the power settings: You can try adjusting the power settings on your monitor to see if that resolves the issue. Go to the monitor settings and look for options related to power management, such as "Power Saving Mode" or "Energy Saver." You may need to disable these options or adjust the settings to ensure that the monitor doesn't go into sleep mode too quickly or frequently.
Reset the monitor settings: Try resetting the monitor to its default settings to see if that helps. Go to the monitor settings and look for an option to "Reset" or "Restore Defaults."
Try a different cable: If the issue persists, try using a different cable to connect the monitor to the Mac mini M1. It's possible that the current cable is faulty or incompatible with your setup.
I hope one of these solutions works for you. Let me know if you have any other questions!

The 2011 released P2412H was never tested on Apple. Dell validated the P2412H on Windows XP/Vista/7. Post the question on the Apple Forum to see if any Mac mini M1 users are using the P2412H.
