Bash list all display output ports
I am looking for a command which prints all visual output ports a laptops has.
I have searched Stack and Google for a while now but I cannot find an answer.
The closest I got is xandr

Unfortunately this output doesn't show the information I need. The information from xrandr is not accurate.
Tried lspci, dmesg(maybe it is in there but couldn't find it), lshw and possible some more hardware listing commands.
The ideal situation would be
VGA x1
HDMI x1 or mini
DP x1
DVI x1
But a finger at the right direction would be greatly appreciated

So I am messing with trying to change dual monitor setup on my machine and found your post. Because I'm interested in the actual display I'm looking for EDID resource from the attached monitor:
find /sys/devices -name "edid"
which produces an output like:
/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-HDMI-A-1/edid
/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-DVI-D-1/edid
/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-DP-2/edid
/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-HDMI-A-2/edid
/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-DP-1/edid
not all of which are valid but if you look at the individual folders in the /sys stuff theres file called status that looks like:
cat /sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-DP-1/status
connected
also more details about the connected display devices (vs the actual video card output) by doing something like:
cat /sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-DP-1/edid | edid-decode

This is a complicated problem.
xrandr will display any and all outputs according to the knowledge of all the GPUs that are under control of the X11 server. But a hardware manufacturer may add built-in converters to e.g. convert a GPU chip's DisplayPort output to DVI, or just leave some of the GPU's outputs unwired. The GPU, and by extension xrandr, has no way to know about changes like that. Also, a listed DisplayPort output might physically be a Mini-DP or a Thunderbolt connection.
If you have a laptop with two GPUs and have one of them disabled (either through BIOS or by software like Bumblebee for NVidia Optimus technology), the output information of a disabled GPU will obviously not be available to xrandr.
Another way to approach the problem might be using dmidecode: with dmidecode -t 8, you should get a listing of all connectors/ports the hardware manufacturer has described in BIOS DMI data. However, this information may not always be correct or complete: I have a laptop that lists no DMI connector information at all.

Unfortunately this doesn't give me the output I am looking for. I dont have a problem with substracting output but with the inacurate information from xrandr. I have a EliteBook 820 G1 which does not have a HDMI port but xrandr displays HDMI x2.

So I am messing with trying to change dual monitor setup on my machine and found your post. Because I'm interested in the actual display I'm looking for EDID resource from the attached monitor:
find /sys/devices -name "edid"
which produces an output like:
/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-HDMI-A-1/edid
/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-DVI-D-1/edid
/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-DP-2/edid
/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-HDMI-A-2/edid
/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-DP-1/edid
not all of which are valid but if you look at the individual folders in the /sys stuff theres file called status that looks like:
cat /sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-DP-1/status
connected
also more details about the connected display devices (vs the actual video card output) by doing something like:
cat /sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/drm/card0/card0-DP-1/edid | edid-decode

This is a complicated problem.
xrandr will display any and all outputs according to the knowledge of all the GPUs that are under control of the X11 server. But a hardware manufacturer may add built-in converters to e.g. convert a GPU chip's DisplayPort output to DVI, or just leave some of the GPU's outputs unwired. The GPU, and by extension xrandr, has no way to know about changes like that. Also, a listed DisplayPort output might physically be a Mini-DP or a Thunderbolt connection.
If you have a laptop with two GPUs and have one of them disabled (either through BIOS or by software like Bumblebee for NVidia Optimus technology), the output information of a disabled GPU will obviously not be available to xrandr.
Another way to approach the problem might be using dmidecode: with dmidecode -t 8, you should get a listing of all connectors/ports the hardware manufacturer has described in BIOS DMI data. However, this information may not always be correct or complete: I have a laptop that lists no DMI connector information at all.

I by "ports" you mean "holes in the casing where I can stick a connector" then the only place where those may be listed is the manufacturer's web site. (Example for the HP EliteBook 820 G3.) Only the manufacturer knows what they have designed and assembled.
xrandrlists all the ports which the GPU provides; the manufacturer, in their wisdom, may chose not make all of them available externally, or to provide extra connectors via converters.– AlexP
