Hi @armada45
Thank you very much for sending the diagnostic logs.
Based on the logs, you have splashtop display hook driver (lci_proxywddm) running on your machine. This product is currently not compatible with spacedesk.
You have to uninstall it, then reboot before you connect a spacedesk viewer.
To uninstall, just open the splahstop Wired XDisplay Agent on your machine the click on Advanced, then Uninstall the Virtual display driver.
OR just open the spacedesk Drive Console -> Diagnostics -> Incompatible Software, then click the Uninstall button beside the lci_proxywddm driver, then reboot your primary machine.
