My monitor wont turn on/connect properly

MSI MPG 321CURX. I have 2 displays, this is my main display and Monitor 1 in windows. Originally had it connected via HDMI and had to manually turn it off anf on again every time I turned on my pc or woke it up. Now I have it connected via DP.. and now I "only" have to manually turn it off and on again after booting most times. like 4/5 times.
