Just to clarify, I contacted Vivitek about the difference between all these models and the only difference is the firmware. You could flash either one of the models with the others firmware and it would technically be that model. The higher end model (H5085) just has some extra picture adjustments. I also got some confirmed specs. All three use the 0.65" DC3 DMD chip using a 6 segment (RGBRGB) color wheel running at a 6x speed. Just thought I would share the info!
