This software is absolutely great. I use it since over 7 years, and it allowed me even then to output from my old MacBook Full HD Frame Packed 3D images to a 3D beamer. It has incredibly many features. Moreover the developer, Stéphane Madrau, is extremely helpful and fast, if there is any problem. And if you ever bought a version, every update is free. As I said, I bought it over 7 years ago, and the update to the newest version that runs on the newest OSX versions, is still free! Unbelievable. So, I can recommend it completely, if you want to output via monitor settings a special format (like Full HD Frame Packing) that is not supported by default, but still possible by your hardware! Big thanks to Stéphane!
