Hi @xiao,

Please follow the steps in your spacedesk Viewer to see if this fixes your issue:
1. Go to Settings > Quality/Performance
2. Click on Encoding Type, then select Software Encoding MJPEG (forced)

I did that before posting here, but it still takes time to work after plugging and unplugging, closing and reopening the app, each multiple times. Before I updated, I would open the app and they both automatically connected like monitors would. Any other suggestions?

HI @xiao,

For further analysis of the issue, please send us the logs of your Primary PC by opening the spacedesk Driver console as administrator and clicking on Diagnostics then follow the steps below:

1. Download the DebugView.
2. Check the Diagnostic Collection box.
3. Reproduce the issue e.g. by connecting the spacedesk Viewer app.
4. Uncheck the Diagnostic Collection box.
5. Click “Save All Information” button (this might take a while to finish).
6. Compress/Zip the folder which contains the logs, then attach to your next reply to this post. If the folder exceeds 512kb, you may upload it to Dropbox or Google Drive then include the download link on your next reply.

Thank you.

Hi @ernest,

Thank you for sending your logs. Can you try reinstalling your spacedesk viewer app and try connecting again?

I decided to update on a whim and now my tablets show black screens and won’t connect no matter how I connect them. If I can get an image on one, it fails once I connect a second device. I wish there was a way to downgrade until the new version works, I need this to draw ASAP!

Hey @xiao and @ernest, I totally get how frustrating it is when something that worked perfectly suddenly breaks after an update. A couple of things you could try while the team looks into your logs: first uninstall and reinstall both the spacedesk driver on your PC and the viewer apps on your tablets. Double-check that Windows Firewall or any antivirus isn’t blocking spacedesk because updates can reset those permissions. Also, in the viewer settings try switching between the hardware encoder and software (MJPEG) encoder to see if that stabilizes the connection. Make sure all your devices are on the same Wi-Fi network and that it’s a strong connection. If it’s still acting up, keep sending those diagnostic logs Renz asked for, they really help the devs pinpoint what’s going on. Fingers crossed you’re back to drawing smoothly soon!
– Hope you find it working. dear🫡

Hi Spacedesk team, I still am not able to get the USB Andriod connection working. Besides reinstalling both Viewer and Console, I have tried changing cables and viewer devices and no success.

I think it is worth noting that connection via LAN works. It is only connection via USB that shows a black screen on my viewer device and laptop is unable to detect additional display.

Hi @ernest,

If you have any pending OS updates in your viewer device, please update. Also, when connecting to your PC via USB while spacedesk’s Android USB option is turned off, what USB mode is being used? In order to connect to spacedesk USB, you should have the USB mode to “Transferring Files”/”FTP” or “Transferring images”/”PTP”. Please see attached image as reference.

Hi @spacedesk-renz,
Yes, the USB mode is File Transfer/Android Auto.

To update, I saw another topic:
https://www.spacedesk.net/support-forum/topic/black-display-when-using-usb-3-0-3-1/

I then tested out with a USB 2.0 cable (USB A to USB C) and it works. Therefore it seems the issue is the same as the other topic.
