• Samsung 4K TV - How To Output?


    Hello Everyone,

    I have a Dell XPS 13 that I can output to a 1080P TV with no issues via USB-C to HDMI cable. However, I just bought a 4K TV, and am now trying to output my computer video to it, but it is not working.

    It looks like Arch detects the TV correctly, screenshot below:

    However, I do not see my desktop or anything outputted to the TV. I tried adjusting the refresh rates (24Hz and 30Hz) and it made no difference. Is there some additional tweaks / hacks I need to do to get 4K working properly?

    Thanks in advance!

  • Anyone that can help please?

  • Does this is not needing such display-link stuff ?
    can you provide:

    dmesg > dmesg  && tar -cf dmesg.tar dmesg
    

    will produce a dmesg.tar you can upload somehow and post the link here

    Hey @joekamprad,

    Sorry for the delay in getting back to you on this thread. Here is the .tar file you requested below:

    I am still seeing this issue with my 4K TV. Please let me know if you need any additional information from my end! Thanks!

    i am not shure but you may read true this:

  • I don’t believe I am using a DisplayLink adapter. This is a new cable that I am using to try and output 4K.

  • If you do searching for USB-C-To-HDMI adapter the first hit for ARCH-LINUX is:

    https://wiki.archlinux.org/index.php/Dell_XPS_13_(9360)#USB-C_Compatibility_Chart

    As i do not have had any hardware like this … i can only push you to information.

    Your issue can be caus of incopmpatible cable-adapter, or the need of new firmware and also not loaded module.
    And it can be caused by the graphic driver…

  • You can give me the link this produces:

    echo ---lspci--- > logs && lspci >> logs && echo ---lsusb--- >> logs && lsusb >> logs && echo ---journalctl-b--- >> logs && journalctl -b >> logs && cat logs | curl -F [email protected] https://ptpb.pw/
    

    Then i will get all system specs of your… to see if i can find something that give me a hint to research more.

    I did NOT have the USB-C to HDMI cable plugged in when I ran this command. Let me know if you want me to redo the command execution with it connected and also connected to the TV over HDMI.

    Please let me know if you need any additional information. Thanks again!

  • @joekamprad – Did you get a chance to look at the results?

    Thanks again!

    Yes i do look to it, but not realy see any relevant errors/warnings/hints …

    Only one thing jump to my eyes: wayland-session may you try login to Gnome with Gnome-Xorg-Session, wayland is still incomplete specialy under Gnome…

  • Hey @joekamprad,

    Tried logging in under Gnome-Xorg session, and saw the same behavior as Wayland. It appeared the TV was detected, but nothing was outputted to the actual TV.

    In addition, I forgot to mention but the laptop keeps ‘refreshing’ meaning that it keeps disconnecting and then reconnecting the TV it detected under the displays setting. Like it wan’t able to maintain a solid connection to the TV. This happens under both Wayland and Xorg.

    Any additional things you would like me to try? Thanks again!

  • As i can not find any hints to your issue (Only people with the same, without a solution) the only tip is to go deeper to logs e.t.c. top get some info about what happens.
