Hello,
After an update of Windows 10, it is not possible to see the screen if the screen is either physically turned off or by the save screen.
Do you have a remedy for this ?
Thank you
Patrice

    Hi,

    This same problem is happening to me since this Windows 10 update, and I had to stop using TightVNC after years of flawless operation.
    Is it possible to solve this problem?

    Thanks a lot!
    Teo

    What versions of TightVNC are running on the hosts with this issue? I have experienced these black screens too under Win10.

      In my case it happens with every version of TightVNC I tested (at least from 2.8.27 but also earlier for sure).
      Currently both the server and viewer are the up to date version 2.8.59, and the black screen is still there. :-(

    Hello, I have the same problem (black screen), on three machines, Windows 10, no monitor attached. If I connect the monitor, I get the correct image. I have installed 2.8.59.

    Try activating the TightVNC Server on the host as service .
    I had the same black-screen problem when running the TightVNC Server "on demand".
    I changed the TightVNC Server to a Service and it worked fine.
