Hey!
Note: I posted this Thread in MacOS Monterey Cathegory in this Forum - with no answers. So this is my 2nd try :-(
I have a strange Problem, wich i cant solve.
Setup: 27" iMac Late 2015 Base Model with 1 TB SSD @ Latest macOS Monterey
External Monitor: Dell Alienware AW3418DW
The external Display is connected via HDMI to Thunderbold 2 Cable.
Display works without any Problems.
If i shutdown the iMac or leave it in Standby the Display won`t turn on automatically (the external Display is not turned off and in Standby) if i start the Machine by pressing the Powerbutton on the iMac or - while in Standby - pressing Keys or move the Mouse the display remains black. I manually have to start the external Display and everything works fine. The iMac is not starting the display itself. Maybe its macOS related?!
I cant find anything regarding the Problem on the Internet. I tried different cables with no effect.
Any Help?
Thank you!
