    I use a tablet samsung S9+ and a phone samsung s21.
    When S9+ is USB and s21 is Wifi.. all is ok but wifi is slow and sometimes very slow.
    So I try to connect both via USB.
    I see on the spacedesk Desktop panel both are now on USB (USB(2 connected))
    and I removed Wifi from the s21 to make sure it’s only USB.
    But the s21 displayes a black screen.
    In display settings (windows10) I see the s21 screen greyed out.
    in the spacedesk Desktop panel s21 says : “Display mode Detached”
    where the s9+ says “Display mode Extension mode”
    If I remove the s9+ USB then s21 goes in “extension mode” and I can use it.
    Not sure what I need to do to get both in extension mode ?

    thx for help.


    Hi @sgodzillap,
    Could you please open the Windows Display Settings on your primary machine and click the detached/greyed-out client then just attach it by selecting extend from the drop-down menu.
    You can also refer to our CONFIGURATION AND SETTINGS
    -> Windows Driver (Primary Machine) -> Desktop Extension or Desktop Duplication (mirror) Settings in Display Control Panel chapter in our manual –
