change in display port may be necessary
Sitting at my Samsung monitor is arranged to display port 1.1 but it works with 1.2 too
Suggestion …If you somehow have plain black screen, and if the computer does not automatically restarts, then check if you can see the mouse. Then if it did not restart and if you can get any image, begin to play around with cables, change the port..
