Vnc windows 10 login stuck

Hi i am running Tight VNC server on a remote PC which has 2 monitors.

When i log in with a VNC viewer, it prompts me for a password and i am presented with the Windows 10 lock screen, everything normal.

When i hit enter to type my windows password the screen goes black. The cursor then appears to be stuck in the center of the screen.

If i type my password anyway and hit enter nothing happens. After some time the lock screen returns or if i reconnect.

The target machine has two displays but i am only presented with the 1080p res of the secondary monitor.

Does anyone know some way around this windows + VNC login problem, without access to the target machine? I have tried different VNC clients and none of them show both monitors or make the password field visible, just a black screen after the initial win 10 lock screen. Ultra vnc viewer the screen flashes grey and white after hitting enter.
