I don’t know what you mean by a „detached secondary display“. By that are you referring to when Spacedesk is running? My PC consists of 3 monitors at all times, and when I look in Display Settings, there is nothing detached. All 3 monitors have the desktop extended to them. They are working fine. Even when I run Spacedesk, nothing shows up as detached in Windows Display Settings.
Regarding Virtual Desktop, are you saying disabling it is not enough? I need it to run my VR apps and uninstalling it is not an option. If a complete uninstall is the only way Spacedesk will run, then I’ll have to find a solution other than Spacedesk.
