Thank you @Josef Swanberg and @RBeddig. I appreciate your replies. @RBeddig If it's not too much to ask: in our case, we'll have zoom lenses on all the projectors, so we'll need to measure throw ratio as well I assume. I guess the best way to measure is to simply put a temporary flat surface in front of the projector and measure the throw ratio and lens shift manually, right? Or do you use a different way (I hope I'm not asking you to divulge any secrets here ☺️ )?
Thanks, as always!
