Bonjour,

Is it possible to configure 3 monitors on an nvidia card gtx 1050ti, one
FHD (1920x1080) or 4k and two other monitors with a standard resolution
(1280x1024).

The asus version of this cards has 4 ports: 1 hdmi, 1 dp, 2 dvi

Thank you.

Probably it is possible, but it would be helpful to
have more details, for example which distribution,
version, etc.

You're a little conservative... :-)

Which desktop manager? KDE, Gnome, XFCE, ...?
Which graphic card driver? Nvidia or "nouveau" or else?

Anyway, in "Settings->Display" usually it is possible to
configure a multi-monitor setup.
At least on my system, which is using F-27 with XFCE.

I never tried 3 monitors with different resolution, so
I'm not sure about this, but that could be a starting point.

If you've the official Nvidia driver, there should be a
software, "nvidia-settings", which could also help to
achieve your goal.

I think that the "official" nvidia driver has more possibikities than
nouveau.

I read somewhere that nvidia driver for linux has some limitation to use
only 2 monitors... fake news?

I'm not sure, but it is not clear to me which problem
are you having, then.

Did you tried and it was not possible?
It was possible, but it failed?
How about "nvidia-settings"?

Ah! I did not buy this card yet... I enquire if what I want to do is
possible, if someone had experienced something similar.

OK, now I got it.

Sorry, I've no experience with 3 monitors (and that card,
but this should be less relevant).

I have 4 monitors on a fedora 27 box but with 2 graphics cards, built-in
Intel and GeForce add-on, Intel and nouveau drivers respectively.

I run them Zaphod-head style, i.e. independent screens, but before I
configured them this way (my own xorg.conf), running startx had them as
one screen (no xorg.conf).

A 3 monitor setup on a graphics cards that supports it should be
possible, emphasis on the should.

I don't know much about hardware, so I was wondering if a card has 4
different ports, these ports are "and ports" and not "or ports", I mean:
you can plug as many monitors as the number of ports... Am I right? And
is there a limitation (due to power supply, resolution... anything else...)

I don't think so. Some cards have more physical ports than the number
of monitors they can actually drive. I believe your card can only drive
three monitors:

Not sure where the limitation is, some ports may carry the same
"signal", presented different ways.
