Hi guys, it’s a very relevant topic and worthy of clearer explanation.
1080p via pixel shifting is every bit as native as almost all consumer 4K projectors. You get a 60hz refresh rate and 1920x1080 pixels on the wall.
If you don’t interpret it as 1080p, remember that other display technologies like wheel-based projectors (lamp light instead of led light) also use similar tricks: a lamp based projector has a rotating wheel which alternately shows red green and blue channels of the image. Some also have yellow or white. So you never really see the entire rgb pixel at once. In fact even on non-pixel shifting dlp the same principle applies, the mirrors alternately show each separate colour channel one after the other.
The speed of this switching is fast enough that you typically won’t notice a different even at 60hz and surely not at 24hz. But this is a bit subjective, some people are more sensitive to this, just like the “rainbow effect” on wheel based projectors.
We don’t believe that this qualifies as false marketing. On the other hand, there are many advantages to using this newer DMD than the bigger 1080p option without pixel shifting. It uses substantially less power which makes it possible to make the PicoPix Max so portable, and for the battery to last up to 3 hours long. Where it makes sense to use the larger 1080p DMDs, we’ve done so, for example on the Screeneo S and U series projectors.
Hope this helps!
