I am facing blank screen issue when I connect to Windows 2012 or Windows 2016 server. I am running vnc in service mode.
In user mode, as long as Windows RDP session is active then only I can use VNC. The moment I close or minimize RDP session the VNC session does not respond to any input.
If I try to connect in service mode, I see only a blank black screen and does not respond to any user input. Is this a known issue?
I have tried installing ultravnc 32-bit and 64-bit both one after another.
I have attached snapshot of the vnc server settings. Please help resolve.
