Ah, yes.. strictly the camera seeing that, not me. No noticeable "rainbow" effect at all, and I've run a LOT of content through it now.

From what I have read, I think this BenQ uses a RGBRGB wheel. Not sure how fast it spins though.

Very very pleased with this projector!

Now I am trying to get a permanent screen setup worked out, aiming for 100" diagonal at about 10' from the viewers' eyes. I have ordered a fiberglass backed 100" pull-down from Amazon -- Costco also has a similar item for $100 less though. And if I can work out how to store a shop-built rigid screen the cost will be about $20 instead.
