Are you using Extend mode? Could you please try hovering your mouse or a window far beyond your primary screen and check if it will be visible in your secondary screen?
Could you also check the status of spacedeskService.exe in the Task Manager under ‘Processes’ or ‘Details’ while the issue is happening?
In the meantime, there are a few things you could try:
– Please make sure that your Graphics Adapter driver is up to date. If it’s not, please try to update it to the latest version.
– Could you please try the ‘Clear spacedesk settings’ and ‘Clear Windows Display Settings’ buttons in the spacedesk Driver console?
– Please note that we recently released new versions for the Windows 10 viewer and Android viewer. Also, make sure to update your spacedesk Driver to v1075.
