Spacedesk no longer connecting properly

#1 · 10/10/2025, 05:54

Hello!

I have had spacedesk working for about a week but all of a sudden today, when I try to connect all I get is a black screen with the text „Connected – Display OFF“ bouncing around. I have tried uninstalling both the app and the driver and have reinstalled the android app as well as the new 2.20.06 driver but the issue still persists.

Running on a Win11 PC and connecting to a Google Pixel Slate

I have attached the zip of the debug diagnostics folder

Hi @andy-4,

thank you for sending the diagnostics. It showed that there was a failure in initializing the virtual display. Please reboot your Windows PC and try spacedesk again.

I have since rebooted my PC as well as my tablet but the issue is still happening

Hi @andy-4,

please try the following:
– check in Windows display settings if the spacedesk display is detached. If it is, set it to extended or mirrored display.
– update the graphics adapter driver to the latest version
– in the spacedesk viewer settings, select Software Encoding

If none of the above helped, please send again the diagnostics.

Hi @spacedesk_nicole

My spacedesk randomly worked once the other day but then when I needed it today I have the black screen with „Connected – Display Off“ error again.

I have checked the Windows display settings and it does recognize that I have a 3rd screen attached and my display is extended. My tablet also shows up listed in the spacedesk Driver Console connections

I have the latest nvidia studio driver 581.57

I’ve set the encoding type to software encoding from the default automatic selection but that didn’t change anything

I have attached my diagnostics again

Hi @andy-4,

thank you for the update. Our spacedesk display driver failed to create a DirectX device using the Nvidia GPU. Usually, this can be fixed by a reboot but in your case, it is possible that your machine is running out of RAM.

Do you have a game running or any application that heavily relies on the GPU? If yes, could you please try to connect spacedesk first before running the game/application and see if the spacedesk viewer shows the frames.

Please also try to use a smaller resolution for spacedesk.

@spacedesk_nicole

I think that might be the issue, thank you! I was running firefox, obs, and blender all at the same time
