i run qDslrDashboard successfully on the Raspi with the solution from the board. There is an element14 Touchscreen attached to the Pi working fine.
But when i use the HDMI to an external screen and starting the dashboard it is staying black

The same issue when i start the pi without touchscreen/external and connecting me with VNC. Every other software is running and displayed fine.
Does anyone using VNC successfully or have an idea whats wrong with my settings?
Thanks
Max
