Connecting multiple external screens to Ubuntu Linux

[Gabor Szabo]

Hi,

I have a Thinkpad (
https://www.lenovo.com/il/en/laptops/thinkpad/13-series/ThinkPad-13-Windows-2nd-Gen/p/22TP2TX133E
). It has a single HDMI slot but when I run xrandr I get:

Screen 0: minimum 320 x 200, current 1920 x 2160, maximum 16384 x 16384
eDP-1 connected 1920x1080+0+1080 (normal left inverted right x axis y axis)
294mm x 165mm
.....
HDMI-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y
axis) 510mm x 287mm
....
DP-1 disconnected (normal left inverted right x axis y axis)
HDMI-2 disconnected (normal left inverted right x axis y axis)

(The .... are just lots of lines of possible configuration).

Based on this (and on my lack of understanding) I could connect another
monitor to DP-1
and one to HDMI-2, but I don't know where can I plug them in physically?

If I understand correctly an HDMI-splitter might work, but the screens
connected to that would show the same image. (Mirror configuration.) I
would like to have different content on each screen.

Any idea?

In a more generic question: what do I need in my computer so I can have
more than 2 displays showing different(!) content? Do I need a separate
graphics card for each display?

regards
    Gabor
