Not only DLP. Some laser projectors use a color wheel to get the same effect; other laser projectors use multiple lasers, but pulse the colors individually and you get a similar effect; probably there are some laser projectors that do all colors simultaneously too, just as there are some DLP projectors with 3 DLP surfaces and prisms/etc to split and combine the light. My laser projector does the pulsing, I find it slightly less distracting than I remember color wheels being, but it's very similar; thankfully the family has gotten used to it; I only notice it on content that encourages a lot of fast eye movement.
- CarVac 2y agoScanning displays like a laser projector or a CRT will flash any individual spot but the illumination is almost continuous, so people have less issues with them.
- toast0 2y agoI'm talking about laser illuminated panel projectors used for viewing film or video content, not scanning lasers used for light shows. Scanning a laser beam is a lot more difficult than scanning an electron beam, so rasterised displays from a scanning laser are limited compared to CRTs.
- CarVac 2y agoAh, those are just wider-gamut conventional projectors.
