• Dear Psyche, Our projectors have fast enough color wheels and with improvements in technology that the rainbow effect is largely a thing of the past. Of course some people may be more sensitive to this type of effect. This unit will downscale any 4k signal to 1080p as it is not a native 4k projector, it is simply 4k ready so you don't have to worry about compatibility with higher resolution media and sources.

• This is not a 4k projector, but can accept a 4k input. I have noticed the rainbow effect from time to time. It seems to vary depending on the show.
