I’ve been using spacedesk for awhile now and for some reason if just don’t want to show display this has happened once before but I fixed it by updating my Nvidia drivers but unfortunately I don’t have an update this time and dont know how to fix it also it pc really lags when i activate it which doesn’t usually happen.
Could you please check for any incompatible software, just run the spacedesk Driver Console -> Diagnostics -> Incompatible Software Products.
if there is, please try to disable or uninstall it, restart your machine then try again with spacedesk.
Could you try the following?
– turn Server from On to Off in spacedesk Driver Console
– Restart your primary machine
– try reinstalling your Graphics Driver
