Hey guys!
I’m new to Fedora 39, and I would like to know how to project my notebook screen onto a Samsung Smart TV.
On Windows, I know it’s very easy, but on Linux systems (I’ve tried it on Ubuntu too) I’m having difficulty.
I don’t just want to share a YouTube video on the TV, I want to have the option to duplicate the screen, extend it or be able to choose between one and the other.
It is possible?
In advance, thank you very much! 
Depends upon the TV as well as how you wish to use it.
There is an app gnome-network-displays that can project the desktop image onto the newer Samsung TVs. I use it for 2 different TVs that are both fairly new. Copies the desktop monitor onto the TV.
There is also the ability to connect via DP or HDMI to an external monitor and use it as a second monitor, either mirrored or spanned display.
From your comment I would assume you simply wish the desktop screen to be displayed on the TV so if you install the app mentioned above then launch it from the app icon it should be able to connect.
Isn’t it as simple as plug in an HDMI cable?
Or did you want to use a wireless video feature?
If so what protocol does the TV support?
I’ll try with gnome-network-displays.
In this case, when I connect an HDMI cable, nothing happens. How can I know if there is an HDMI driver on my note?
But, the idea is to use it with Bluetooth, and I don’t know what my TV’s protocol is. I don’t even think any novice user knows. 
This type of feature is the least expected in a system, it could be easier in Fedora.
So, installing gnome-network-displays worked in part, as it only connects once, then reports an error in the application. Then, you need to turn off the TV and restart the app to work again.
Anyway, as it worked in parts, I’ll close the topic.
In time, I needed to install GStreamer Multimedia Codecs - H.264. So if someone is going to follow these tips, they might need to install it too.
Thanks! Until!
That sounds like a problem in managing the TV. The TV has the ability to switch inputs and when using a different input than normal the user must select the alternate hdmi input. In most cases the tv does not automatically switch to a different input.
I don’t know of any TV that uses bluetooth video input, especially when using 4k graphics.
Mine that is less than 6 months old certainly does not.
