Hi all,

To expand on the title, after 2 seconds of connection without issue, screens on both devices (Win10 64bit) start flickering/flashing black. The primary device becomes unresponsive until I disconnect.

Any pointers?

Thanks!

Hi @bbpresident,

Did you notice any error notification in the primary machine side upon connection attempt?

When it starts to flicker, did it disconnect eventually?
Does it give any error code in windows viewer app?
Make sure to disable the auto-reconnect in viewer settings, so it will not try to reconnect.

For further analysis, could you please run dxdiag.exe on your Primary Machine, click "Save all information", save the output file (Dxdiag.txt) and attach it on your next reply.

Hi Lea, thanks for your reply!

I do not experience any error or disconnect and auto-reconnect is disabled.

DxDiag.txt is too long for this message, is there a way to attach the .txt directly?

Thanks!

Hi @bbpresident,
You can attach it on your next reply. Attach option should be visible below the text editor after first or second post.

Hi @bbpresident,
Thanks for sending your dxdiag info.
You Dxdiag shows an AirDisplay driver currently installed on your machine, can you try to run "devmgmt.msc", go to Display adapters -> Air Display (Microsoft Corporation - WDDM v1.1) and right-click Disable device.
Reboot your primary machine and try again with spacedesk.

If flickering problem still persist, could you please try to remove/uninstall your AirDisplay software completely on your primary machine and check if the flickering on spacedesk will be gone.

Looking forward to your feedback.

Hi Lea,

Thanks for your response.

I installed Air Display as an alternative to Spacedesk because of this issue: the issue predates Air Display on my devices.

Therefore, uninstalling/disabling Air Display did not work unfortunately.

Thanks again for your persisting help.

Hi @bbpresident,

Thanks for the feedback.
First, please try to update your NVIDIA GeForce GTX 750 Ti graphics driver.
You can download the latest driver from their website - https://www.nvidia.com/Download/index.aspx.

If updating the GPU did not help, please try the following:
- run "services.msc", find spacedeskService then restart it
- run "devmgmt.msc", go to Display adapters -> spacedesk Graphics Adapter, right-click disable-enable it.
Try again with spacedesk connection and if the screen flickers again, wait for 5-10 seconds and disconnect.

Then please send us the following for further analysis:
- all the *.etl log files in C:\Users\Public\spacedesk_logs folder.
- go to C:\ProgramData\Microsoft\WDF, then copy (2-more) most recent WudfHost_ext__xxxx.dmp
Please take note that ProgramData folder is hidden by default, in case you cannot find it you should enable first the "Show hidden files, folders and drives".
Just open a File Explorer -> View -> Options, on Folder Options window click View tab then click the "Show hidden files, folders and drives" to enable it then apply the changes.

Save all requested files in one folder, then right-click -> Send to -> Compressed (zipped) folder, then attach the *.zip file on your next reply.

Looking forward to your feedback.

Hi Lea,

Restarting the service or display adapter did not work unfortunately.

The .etl files are attached in a zip, the WDF folder was empty.

Thanks again.

Hi @bbpresident,
thanks for sending the log files. We will analyze it.

By the way, did you already update to latest Nvidia driver?
Can you also quickly try to click the spacedesk tray icon on your notification task bar, to open the spacedesk Server window, then click the "..." button to display a menu, then select "Clear All display Settings" then try again with spacedesk.

Hi Lea,

Yes, drivers are up to date, and sorry to say clearing display settings didn't work.

Thanks!

Hi @bbpresident,
Is this the first version of spacedesk you ever tried?
Or did you try spacedesk before (old version) and it worked but now it's not anymore?
