I’m new to Vine and am using it to control my Mac desktop with a very large screen from my MacBook Pro.
On other VNC servers, there is a command line option, -geometry, that sets the screen size seen by the client. It can be something other, usually smaller, than the physically connected display. (This is different than scalling the large display down, which I see how to do in the client.)
I can’t find a similiar thing in Vine. Am I looking right at it somewhere and not seeing it?
