Whenever I turn on my pc, it connects okay to my monitor because it says "DP Input" when I turn them both on, NOT "DP Input No Signal" (That's what it says when there is no signal). But, after it says "DP Input", the message disappears and the screen is black but kind of lit up. I also noticed that the red light next to the cylinder icon on my PC case isn't on. My fans are working by the way.
