Frequently Asked Questions
Does it run in a virtual machine?

Yes, Operator Terminal Expert is the current line for Harmony panels; Vijeo projects import with a conversion step.
Can screens scale between panel sizes?
Projects support multiple targets; design the master layout for the smallest panel you will ship.

Tips from Real Projects
An OEM shipping three panel sizes from one project learned to design for the smallest screen first; widgets that fit a 4.3-inch display scale up cleanly, while the reverse never works. Small-first is a rule worth engraving.
