black screen
Hello, I’m having an issue using spacedesk on my PC with a Samsung Galaxy Tab A7 (model SM-T225) as a second monitor.
The tablet tries to connect via USB cable and also via Wi-Fi, but the screen just stays black. On my PC, spacedesk recognizes the tablet as a second monitor, but no image is displayed — it only shows “1 connection(s) pending…” in the spacedesk notification.
Here’s everything I’ve tried so far:
-
Enabled USB debugging on the tablet
-
Revoked and reauthorized USB debugging
-
Switched USB cables (tested with data-transfer capable ones)
-
Reinstalled spacedesk on both PC and tablet (latest versions from the official site and Play Store)
-
Enabled “USB Cable – Android” in the spacedesk Driver Console
-
Tried Wi-Fi connection on the same network (still shows a black screen)
-
Temporarily disabled Windows Firewall
-
Updated the tablet’s system software
The tablet tries to connect, but it never completes. The app shows “Display: OFF” and then nothing happens.
I would appreciate any help in understanding what might be preventing the connection from working properly.
I’ve also attached the spacedesk log files below where requested.
Thank you in advance.

Hi @rafa3kz,
This issue is currently under investigation. As a temporary workaround, please do the following steps:
1. In spacedesk Android Viewer, go to „Settings“ -> „Quality/Performance.“
2. Tap „Encoding Type“ and choose „Software Encoding (forced)“
3. Try to connect again to your primary PC.
Thank you.
Thank you very much! The workaround using “Software Encoding (forced)” worked perfectly.
I really appreciate your help and quick response. I’ll continue using this setting while the issue is under investigation. Let me know if you need any more feedback or logs from my side.
Thanks again for the great support!
