I am using AnyDesk to mirror a Windows 7 laptop screen onto an Android Tablet. Until recently, everything was fine, but one day, and every time since, I connected as usual but could only see a black screen. I can still see the AnyDesk Settings button, but no laptop picture.
I tried updating the AnyDesk software on the laptop, and reinstalling the app on the tablet. I tried a second Windows 7 laptop with the same result.

I've found this problem recently. I'm using Windows 10 on a HP Laptop with additional HDMI screen (the problem happend with or without the external screen). After a Windows update the problem appeared, so I imagined the problem could be a corrupt configuration related with the screen or something. I'm using the default HP Energy Plan (Recommended for HP), and fortunately I had another customized Energy plan with some parameters changed, and after changing it it worked fine. Let me explain what is the parameter responsible of the black screen issue.
Solution
- Go to "Energy Options"
- Go to "Change the Plan Configuration"
- Go to "Change Energy Advanced Configuration"
- Find parameters group "Interchangeable Dynamic Graphics"
- The parameter "Global Configuration" is the PROBLEM. ___This parameter adjusted with "Maximize performance" works WRONG. ___This parameter adjusted with "Optimized performance" works FINE.
The reason for this is that if you connect to an active session if the target monitor shuts down you will see the screen in black as well.
It also happens for example if you connect by Anydesk to an RDP session and that RDP connection is closed.
The solution would be to log out, connect to anydesk and log in from the connection by Anydesk
Can it be what is happening to you?
This may be a little niche but in my case it was because I had colour correction turned on in accessibility settings (red/green colour-blind) on my tablet.
It's happening when an RDP session is minimized or you're signed out. To make anydesk available as a service you need to install it rather than running as exe. When you run it you'll be seeing an option "Install Anydesk"
At least, it is my case.. :) another solution is using connecting by user account, then you put the user and password and you are in. I think it is also the case if more than one user is logged in the machine. Anythesk then doesn't know which desktop to connect.
