Display connected but shows black screen when I re-connect it

[riore2us]

I often playing a PC game by tablet for screen as a monitor, Not using PC monitor because it’s too cold outside to get out of bed.

Perhaps it is due to an update,
but recently when I connect to the server from the SpaceDesk client app,
I hear the Display connection sound,
but the second display is not recognized and just shows “Connected – Display Off” on a black screen.

If I restart the PC and try to connect from the client before other startup applications are launched,
the screen appears, but if I disconnect and try to connect again, the screen turns black and no display appears.

I have tried reinstalling both the client and server apps,
but the same phenomenon occurs no matter how many times I try.

Please investigate it. Thank you!

Hi @riore2us,

Thank you very much for sending the diagnostic logs.

It seems that you have a Virtual Desktop (from https://www.vrdesktop.net/) installed in your primary machine.
This software seems to have incompatibility issue with spacedesk.
We were able to reproduce the same Display Off issue after installing the Virtual Desktop then reboot.

Please try this workaround steps to make it work with spacedesk:
– open device manager in your primary machine
– go to Display adapters and right-click Enable device the “Virtual Desktop Monitor”
– open spacedesk Driver Console then switch the spacedesk SERVER OFF-ON

If the steps above did not help, the only option is to uninstall the Virtual Desktop app then reboot your primary machine.

Hello @lea,

Thank you for quick reply,
By following the steps specified, I have confirmed that Spacedesk now appears to reconnect without any problems.

As far as I know, Spacedesk is the only application that can stream PC video with sound and wirelessly, so it is very useful.
I am very surprised that such a rare application is available for free.
Hopefully, there will be a separate high quality, low latency service like Duet Pro available for a fee.

I’m looking forward to seeing the service evolve for the better!
