Hi @thegeorge289,
Which driver did you delete? Is it spacedesk?
How did you delete it?
Did you uninstall the whole spacedesk server/driver software properly via Windows Control Panel or via spacedesk MSI installer?
Or did you just remove/uninstall the spacedesk driver in the Device Manager?
Have tried forced rebooting your primary machine?
Is your primary monitor still not working after PC reboot?
