Hi @laim2431,
Current spacedesk is in Desktop Duplication/Mirror mode.
You can easily switch to Desktop Extension mode via Windows Display Settings -> “Extend these displays” in the dropdown menu.
Or via Display switch, just press Windows logo + P hotkey, then select “Extend”.
For assistance, please check the chapter Configuration & Settings -> Windows Driver (Primary Machine) in the user manual https://forum.spacedesk.netuser-manual/#item_469.
