When this happens to me I first make sure that on boot I have something
connected to [an extra video card] video input. Otherwise the card is
likely to not initialize that video input. Shouldn't be necessary for DP
inputs which hot kick in when something is connected.

Next thing I would check dmesg to see the this hardware has been detected
(if there are any conflicts with interrupt numbers or address ranged to be
used, you should see these). I'll also check lspci to see if the system
sees that hardware on the bus.

In general, one shouldn't need to do anything in BIOS. On Dell
workstations when PCI express video card meant to be exclusively used as
video adapter in BIOS they make it "primary video", or sometimes totally
disable onboard video. You can try the last, but if the box comes with no
video output at all (so you will not be able to change BIOS settings),
then you may need to use CMOS setup reset jumper to reset settings to
factory default (of course, you can change BIOS setting without video, but
you will need for that to remember all menus, and mouse the excludes, only
keyboard can be used).

But as it is Dell server, one never knows...

Good luck!
