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 ?
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.
