Dell M6800 Multiscreen initialization sequence

Hi! I have a Dell M6800 and I;m using three external screens. The main screen is connected via displayport, the second screen that the desktop extends via DVI, the third desktop extension is to the laptop's own screen and a fourth monitor that the desktop extends to is connected via HDMI. NOw the problem is that when the laptop is first turned on it starts with onlt the laptop own monitor and the HDMI. If I turn off the computer and simply reboot it then all the monitor's wake up and the laptop's external screens are working perfectly as they should (as they were configured to be working).

Any thoughts?

Is there a way to secure scrren initialization sequence?

Thank you for your time.
