Hi All
There is the vvvvonderful PJ-link module: pjlink by @Colorsound but the projector I am currently working with a Sony VPL-FX52 and it does not support PJ-link.
Before I dig deeper into Sonys PJ talk: http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000015642.pdf I might be lucky that someone else has already made such a module and want to share it.
