Internal monitor not detected

Hey! I'm new to freeBSD and, after a little fight with xorg and the nvidia drivers I finally got to launch xorg and configure all of my monitors.
Except for one. The laptop's internal monitor, and it's not even listed with % xrandr :

   1280x800      74.93    59.81  
   1280x720      74.78    60.00    59.94    50.00

DP-2 disconnected (normal left inverted right x axis y axis)

There should be three monitors listed as connected, or at least available, but eDP-1 is missing (as it is so called under Linux).
What can I do and what info should I provide?
Here's the output of % kldstat :

I have nvidia modeset enabled on /boot/loader.conf. I'm assuming it has something to do with the driver?
 
What I think I am looking at is a desktop with a discrete Nvidia GPU. I am guessing that the GPU has 1xHDMI and 3xDisplayPort.

The screen connected to your HDMI seems to be fine. But you are only seeing one of the remaining 2 displays connected to DisplayPort.

My guess is that the last monitor is hiding as a disabled output. I would then try:

xrandr --output <outputname> --auto

...and see if it hides as DP-0 or DP-2.

But I am a little confused as you write "internal monitor" which makes me think laptop and 2 external displays. I would still try the above but is now wondering how things are connected? HDMI, DisplayPort or USB-C? I have seen system turning off the internal display if something was connected to the external HDMI port. But if this was working with Linux this should be fixable.

As drm, nvidia and nvidia-drm seems to be loaded that seems to be OK. We might need to dive deeper into the Xorg log and see how well the autoconfiguration worked. But these days you rarely need to configure manually and I think we can get by with xrandr.
 
Start with the basic stuff: which graphics card / cards does your laptop have? The pciconf command will tell you. Here is an example:
Code: 
root@kg-core2:~ # pciconf -lv | grep -A 4 vga
vgapci0@pci0:7:0:0:    class=0x030000 rev=0xc7 hdr=0x00 vendor=0x1002 device=0x6617 subvendor=0x1da2 subdevice=0xe263
    vendor     = 'Advanced Micro Devices, Inc. [AMD/ATI]'
    device     = 'Oland LE [Radeon R7 240]'
    class      = display
    subclass   = VGA
Note: this is from my workstation, not a laptop.
