That's exactly what it is, switching rate is alot faster tho.
But all LED machines show this artifact so far, some more, some less - at least for some people. Those who can watch colorwheel DLPs shouldn't bother at all. DLP units with color wheels are simply unwatchable for me, within 20 minutes it feels like my head explodes.
While I can still see color seperation artifacts on LED machines, they are nowhere near as bad as on colorwheel based units. I can also only see them in darker scenes. I've previously mentioned that Public Enemy is a good demo disc for these type of artifacts, the scene when Dillinger hides in the hotel in the forest and the agents are approaching. While moving my eyes across the screen, the higher contrast areas (background/trees, faces/trees) are breaking up in a shade of grey/blue. So this is different to the rainbow artifact of colorwheel based units, where all colors were shown.
I've not had the chance to test the latest firmware on the Mico 50, but I was told it would significantly improve this issue. At least Sim2 is aware of it. Not sure about Runco and others. I can't see any such artifact in brigther scenes or with 3-chip DLP.
I've tried to show this artifact to a couple of other people on the Mico 50, but no one else could see it... lucky me, eh?
