Hi @xude,
Have you done any user account switching or remote desktop connection before using spacedesk?
Could you please run services.msc on your primary machine, find spacedeskService then right-click restart it.
Then try to connect again with spacedesk viewer.
If problem still persist, please send us the following for further analysis:
- run dxdiag.exe on primary machine, click "Save All Information" then save the output file (dxdiag.txt)
- all *.etl files on C:\Users\Public\spacedesk_logs folder
Please save all the requested file in one folder, right-click then Send to -> Compressed (zipped) folder, then attach the zip file on your next reply.
Looking forward to your feedback.

If it shows "Dispay OFF" on your side, please check the display settings window on your primary machine if you can find a detached display. If it's there, please just attach it by selecting Extend or Duplicate (there's a multiple displays dropdown menu box below).

Hi @stoubar,

To further analyze the problem could you please download the 2020_spacedeskDiagnosticTool.zip file here then extract it.

Inside you will find spacedeskDiagnosticTool.cmd, just right-click it then run as administrator.
This script will start a debug view app to capture spacedesk debug traces.
On step 5 it will prompt you to reproduce the issue(just connect the viewer app with black screen/display off status), make sure to do this before pressing any key to continue.
After the script is done, a folder will be created on the same folder as the script file which contains various log files that we need for analysis.
Please right-click it -> Send to -> Compressed (zipped) folder, then attach the *.zip file on your next reply.
Looking forward to your feedback.

Hi @stoubar,
The script includes restarting the spacedeskService that's why the spacedesk SERVER window will suddenly close, but you should be able to open it again upon Step 5, when the script prompt you to reproduce the issue.
Attach option should be visible below the text editor after your second post.

Hi @dtmk,
Did you check the display settings window on your primary machine if the spacedesk display is detached?
What is your spacedesk Viewer type? Android/iOS/Windows/HTML5?
For further analysis, could you please run dxdiag.exe on your primary machine, click "Save All Information", then attach the output file on your next reply.
PS: Attach option should be visible on your side after your second post.

Hi, I seem to have the same issue unfortunately...
I have the Server running on my Laptop (Win 10 64-bit build 19042) and am trying to connect to my iPad Pro (3rd Gen, running iOS 13.5.1). I have tried connecting through the app as well as the HTML Viewer with no success. While the iPad says "Connected - Display OFF", the server shows no connection being made.

Hi @austrianaviator,

Is your auto-reconnect enabled on your iOS Viewer app?
Did you notice any error notification on your primary machine upon connection attempt?
For further analysis, could you please run dxdiag.exe on your primary machine, click "Save All Information", then attach the output file on your next reply.

Thank you for the speedy reply. I have tried to connect with the auto-reconnect both enabled and disabled. Same result. There is also no apparent error message.

Hi @austrianaviator,
Thanks for sending your dxdiag info.
It seems that you have splashtop installed on your primary machine.
You have to remove/uninstall splashtop then reboot before connecting spacedesk viewer.
For more info, please check Incompatible display hook driver chapter in our user manual https://spacedesk.net/user-manual/.

Hi, I also have the same problem: it connects, the connection appears on the server, but the IOS screen (I also tested it on Android) remains black and the message "CONNECTED - DISPLAY OFF" appears.

He won't let me attach the diagnostic file

Hi @blainethemonkey,
Attach option will be visible on your side after your second post.

Did you check on display settings window of your primary machine if there's a detached second display?
Did you also check if spacedesk SERVER window shows any indication that there's a connected viewer (e.g. connections count, on Network connections (remote) tab?
