Thanks for all the info. What I'm doing is a 360 degree projection on large surfaces where the public will be close to the projected images, so the higher the resolution the better. I have been told that the quality is to be high enough that when standing beside the projected image the pixels must not be seen, which is a tall order I know. So it's 6 projectors in a circle, within a concave room of some sort, and the 7th projector facing up to fill in the gap at the top. I have to warp the images across all seven outputs so that it all fits in together. When number 1 and number 6 and top projectors meet, so that the images join well is up to who makes the content. Can the eVigilant products take the image from a TH2G?
