Hello,

You should do the following:
If you use Windows 10 /11 on this PC:

After updating Radmin Server, you need to restart this PC.
2. Check out the latest updates for Windows 10/11.
3. Check if the latest drivers are installed on the video adapter
4. If you use virual machine, try Installation of virtual monitor driver.
5. If it didn't help and there is no a video card with display port \ hdmi
and there is no monitor connected, then try

Create a new account with the same rights in Radmin Server.
To do this, right-click on Radmin Server

If the above option did not help, then try to disable the Display adapter on Radmin Server Side in Task Manager
If you use two video cards, and one of them is Nvidia, disable temporary Nvidia and select to use integrated for rserver3.exe.
Please, check Microsoft remote assistance (quick assist), returns a black screen or does it work?
