Are you "DLP Sensitive" New faster engines fix most of the problem
We started writing about this many years ago when DLP projectors were using 1 X and 2 X or 4 Speed color wheels. That is to say they were not fast enough for the fast action in movies, they were OK for Power-point presentations etc.
DLP projectors & TVs flash parts of a colour one after the other to make the illusion of the whole colour (using your eye/brain visual processing).

Any 3D watching comes with safety warnings, especially for children.
Systems trick you into seeing 3D and upset your natural 3D perception for a short time afterwards.
(So don't go fly a plane).

The only "safe" way to watch 3D is without 3D glasses.

The DLP "Rainbow Effect" This visual artifact is best described as brief flashes of perceived red, blue, and green "shadows" observed most often when the projected content features bright/white objects on a mostly dark/black background (the scrolling end credits of many movies are a common example).
With faster systems most people do not notice the "rainbow" artifact at all.
The effect is likely rooted in the concept of the flicker fusion threshold .
The "Rainbow Effect" is unique to slower single-chip DLP projectors. As described above, only one colour is actually displayed at any given moment. As the eye moves across the projected image, these separate colorus become visible.
With a static picture from a single-chip DLP-based projector, it is easy to understand how this averaging works just fine. Where things potentially start to fail is when there is motion in the image, or when one blinks or rapidly moves one's eyes quickly between various parts of the image. In these cases, the perceptual integration of the image may break down and one might see "rainbows" or false flashes of color, in the image, again the new faster light engines seem to overcome this problem.
As we mentioned at the start the new generation of DLP projectors have via 6 X speed colour wheel made "rainbows" a thing of the past for almost all people.
