I have a Z97X-Gaming 3 motherboard with an integrated graphics card and additionally, I have NVIDIA RTX 2080Ti.
One display is connected to NVIDIA HDMI output and another is connected to the motherboard DVI output which is blank; initially, before the login screen, I can see the output text Ubuntu but then the login screen appears on another monitor which is connected to NVIDIA graphics card and the initial monitor goes blank.
I tried to modify the bios settings but all the attempts were unsuccessful.
Here are the current settings:
and these are the graphic cards:

I would appreciate if anyone provided any suggestion about how to enable double output.
