Thought I might post a thread about this. But I went to a venue the other day and they had a extra wide screen with what looks like 6k, cheap too. It was hard to see, but from what I could tell they had three Benq Fullhd projectors seamlessly stitched together on the screen. Imagine four ones tilted vertically stitched together (4320*1920), how many wide 4k movies could fit in that. ;-)
