Hello. I set up the most recent versions of the driver and android app today (09/13/2020), and can connect my galaxy Tab A as a mirror, but cannot get the monitor wall to work. The Tab A shows up as "Invalid GUID" and continues to mirror. I followed the suggestions given in https://forum.spacedesk.ph/community/discussion-board/cannot-connect-multiple-android-viewers-shows-invalid-guid/#post-4671, but they did not help. Below are my specs. If anyone has a solution, I would love to try it.

PC: HP 14-dk1xxx, AMD Ryzen 3 3250U with integrated Radeon graphics. 4 gig ram (shared), Windows 10 64 bit, version 1909, build 18363.1082.

Tablet: Samsung Galaxy Tab A, model SM-T590, Android 10, kernel version 3.18.124-18974136.

Hi @cynikal,
Is this the first time you try spacedesk?
You can easily switch from Mirror to Extension mode via display settings window.
Can you send us the exported .reg file on your videowall engine?
Just click the "Export Registry settings" button.
Can you also send us your dxdiag info?
Just run dxdiag.exe on your primary machine, click "Save all Information" then attach it on your next reply.
Attach option should be visible after your second post.

This is a new setup for me, yes. However, I don't have an option to attach files showing yet.

Hi @cynikal,
Thanks for sending the requested files.
We were able to reproduce it now here on our side after continuously trying it since few weeks ago.
And it seems a bug on our android viewer app after clearing the data of spacedesk App in the device settings.
We will soon fix it and get back to you as soon as we have new version with the fix.
For now, I was able to solve it on my android device by uninstalling and reinstalling the android app.

OR if reinstalling didn't work try to enable the Auto-Connect in the viewer settings -> Connection, then save the IP address of your primary machine, then close the viewer app then run it again.

Can you quickly try it?
Then let us know the result.
Looking forward to your feedback.

Uninstalled, rebooted the Tab A, and re-downloaded from the app store. No dice, still shows as invalid GUID as soon as they see each other.

How about this? Did you also try it?

Hi @cynikal,
Or try to change any settings in the viewer settings (e.g. enable auto-reconnector set different custom resolution or disable touch/auto-rotation), as long as it's not the default settings.
Once you change it, close the app and rerun it, and once it worked, you can go back to the previous settings.
