Connecting multiple external screens to Ubuntu Linux

[Gabor Szabo]

Thanks for all the replies so far.

So if I understand correctly I might buy a docking station similar to this
one:

Lenovo Powered USB-C Travel Hub - Docking station - USB-C - VGA, HDMI -
Worldwide - for ThinkPad L14 Gen 1, P14s Gen 1,
https://www.newegg.com/global/il-en/p/0XP-006B-001E1?item=0XP-006B-001E1

that connects to the USB-C of my computer and provides an HDMI and VGA
slots so I can connect two screens, one via each slot.
Will I be able to also connect a 3rd external screen to my regular HDMI
slot in the computer?
Will I be able to have 4 different screens?

As I understand this computer has a single graphics card. So how can it
drive more than one screen? What is the limit?
If I buy a desktop computer can a single graphics card drive more than one
screen there?

Any pointers to some explanations how this graphics card to screens mapping
works?
