Hi,
I’m on Fedora Linux 43 Workstation , GNOME , Wayland , with an NVIDIA GeForce RTX 3060 Laptop GPU .
My display setup:
Internal laptop display: 2560×1600
External monitor: Dell S2721DGF, 2560×1440 via HDMI
Problem:
Join Displays works normally
Mirror fails every time, it shows only one screen, when I click on it I get an error:
What I already tried:
Set both displays to 100% scaling
Set both displays to 60 Hz (to the best of my ability: 60.01 and 59.95 Hz)
Tried changing resolutions, but the laptop panel does not offer 1920×1080
Mirroring still does not work

Welcome to Fedora @nagisaa
Could you test an other HDMI cable? Do you have a other option to connect the monitor (usb-c display-port) ?

I first hit this problem a couple of weeks ago when connecting to a projector. That projector is used by lots of people, so I doubt the HDMI cable is the issue. Also, I used this same laptop about a year ago on Windows with external displays and did not have this problem.
One important detail: Join Displays works fine . The problem only happens when I choose Mirror , so the external display connection itself seems to be working.
Please observe the Message :
Changes Cannot be Applied
This could be due to hardware limitations.
HDMI is not an open standard. So can be that on Windows it works different than Linux.
That is why i asked for an alternative connection … Display port on the other hand is open. Maybe with usb-C you have more look too. However for that you probably would need a docking station.

Is there a resolution that both monitors support that you’ve tried?

I see. In that case, my laptop does not have a native DisplayPort output, so the only alternative I could test would be USB-C to DisplayPort .
That said, since Join Displays works , I would expect the cable and basic HDMI connection to be fine. The problem only appears with Mirror, which makes me think this is more about how GNOME/Wayland handles mirroring than HDMI itself.

The laptop display is locked to 2560×1600 (16:10) , and the Dell monitor does not support that same resolution, so I do not seem to have a common resolution available to test for mirroring.

Guessing you’re running into something similar to, Cannot use different scaling on Wayland with clone mode (#2724) · Issues · GNOME / mutter · GitLab .
You could try asking on Gnome’s discourse instance
EDIT: You could also try a live disk of KDE and see if it works.
inxi reports three displays the internal + two dell.

I only have one, so its weird, also both on that output have the same serial number: S2721DGF
Nagisaa:
S2721DGF
that’s not the serial number but the model/type number
coutd you run grep . /sys/class/drm/*/status pls?
EDIT: also have you disabled the internal GPU?

I wanted to suggest the same, but @nagisaa is using the proprietary Nvidia driver, I don’t think that would work on a live system.
