Hi @soratoni,
For further analysis, could you please send us the diagnostic logs of the issue.
On your primary machine, just follow the steps below:
– open spacedesk Driver Console app (via start menu or spacedesk tray icon) then click „Diagnostics“
– if Debug View is not available, please click the download button first
– switch Diagnostic Collection ON (make sure to click Yes in the User Account Control box to proceed)
– try to connect your viewer app and reproduce the black screen issue
– switch Diagnostic Collection OFF
– click Save All Information button (if message box appear, just click No to proceed)
PS: Saving all information will take a few seconds, then please send us the whole folder which contains all the diagnostic logs collected.
Please right-click the folder -> Send to -> Compressed (zipped) folder, then attach the *.zip file in your next reply.
