This only affects both Intel and Nvidia cards and is fixed by changing your intel / nvidia settings to not scale the desktop.
For intel graphics cards a driver reinstall should fix it ( Intel driver update video ).
If you have a mixed nvidia and intel machine that switches bewteen cards then go to the intel control panel for your display and switch the scaling option from "Maintain Display scaling" to "Maintain Aspect Ratio".
For nvidia only machines see below ...
If after updating this you still get a black screen when starting VelociDrone then it is most likely that the registry entries for the screen resolution have been zeroed. They can be manually updated via windows regedit ....
