Error message Gnome-Networks-Display, unable to fix so far

Hi all, I have been trying for literally DAYS to mirror my screen on a wireless display, without any success obviously, and I am really, really desperate for some help.
I hope I am asking in the correct channel, don’t hesitate to redirect me otherwise. Also, I tried to see if similar topics existed, but I didn’t seem to find any, sorry if that was my mistake.

Onwards:
(I use Fedora 41-Wayland)

Here is the issue: I want to mirror my screen on a wireless display (here a simple samsung projector LFF3). I can connect to the device via Bluetooth, and that way I can cast music/media on the projector but NO image, just the sound. I can actually also mirror the screen when I have a built-in option to mirror screen like Youtube does with “Watch on TV”.
But, I cannot mirror the actual screen of my desktop for instance, or videos on VLC, or a work presentation on PowerPoint, etc. This is what I’m trying to achieve. Other people with a Windows computer have easily made it worked by just pressing WIN+K, but Linux distros apparently lack that option, gods only know why.
I have tried Gnome-Network-Display, as it was what I found was supposed to work when I searched online, but I only get Error messages (see picture). Not very chatty error message too, what I am supposed to get from that haha?

I am unfortunately not a pro at anything-Linux, so I am unsure if there is just a command somewhere that I missed that would magically fix it. I really hope that it’s the case, otherwise I am just floored.

I deeply appreciate any help or advice give, and thank you for your time!

TLDR: Gnome-Network-Displays only give Error message when trying to connect to projector. Internet didn’t give me any answers, will you? :pleading_face:

Hi Loraine,
Welcome to the Fedora Forums. People here will certainly try and help you if they know how.
Personally I do not :frowning: :slight_smile:
If no-one chimes in, you could also try the Gnome Desktop forums. Desktop - GNOME Discourse

Best of luck!

Thank you for your kind message! I really appreciate the answer even without a solution :slight_smile: It seems like a very specific problem so I’m not holding out to much hope unfortunately :upside_down_face: I’ll try the Gnome Discourse as well, thanks for the tip!

I had a little look around, and came up with a couple of things to try.

  1. Run Gnome Network Displays as a Flatpak from Flathub
    Install GNOME Network Displays on Linux | Flathub
    And make sure when starting Gnome Network Displays it starts the Flatpak version.

  2. The Projector has Wifi ( https://images.samsung.com/is/content/samsung/assets/au/tvs/product-specs/Updated_The_Freestyle_2023_Retailer_Spec_Sheet_131123.pdf ),
    Try connecting to the projector through Wifi with NetworkManager. And try again with the versions of Gnome Network Displays.
    If that is not enough, you can look into using ‘Miraclecast’.

  3. Not the answer that you asked for but there is a MicroHDMI and you can get some pretty long HDMI cables 10 meters (33 feet) for HDMI 1.4 cables
    5 meters (16 feet) for HDMI 2.0 cables
    3 meters (10 feet) for HDMI 2.1 cables
