Boot will not show, however windows starts, MSI X99

[Gaeflin]

Hello all,

as title says, I turn on the PC, in few seconds Windows starts, however I am not able to enter bios, because the monitor is blank durring the time of bios. It started when I switched to display port from DVI port.

Using:
Mobo: X99A XPOWER GAMING TITANIUM
GPU: GTX 980Ti Asus
CPU: 5820K

Dunno what to do,

with intel mb there two settings to look at one is primany display the other is mult monitor. the first tells the mb what display port to use first. if it set to auto or ipgpu. it try to turn the wrong port on at post and you miss the bios splash screen, the same if you have both a gpu and ipgpu and have the video cable on the wrong post at post. if your not using the intel gpu port on the mb turn off mulit monitor support. make sure your prmany display settings is set right.
