Few things to note, I do sometimes get the rainbow effect, only slightly noticeable, not a big issue at all.
The projector is a tad bright, i've not adjusted the settings at all but the original colour config is fine and I dont know where to start with adjusting it. We generally use it on a white wall, and the blacks aren't very deep at all.
However we got a 150" grey projector screen and the colours look brilliant, so much better than on a white wall, the blacks are now deep and overall picture quality is so much better.
Can you do me a favour? Try running the projector at 71.928 hz (using my settings above), from your PC, and tell me if that makes the rainbows disappear.
In theory, going from 60hz to 72hz could help reduce RBE since the colour wheel speed is synced to the refresh rate. And a 20% reduction is nothing to sneeze at. It's like going from a 5X to a 6X colour wheel speed. Actually, exactly like that, since the w1070 drops to 5X at 60hz so running it at 72hz likely brings it back up to the equivalent of 6X.
I've been meaning to try painting my wall gray, although reducing the brightness doesn't actually increase the contrast AFAIK
, since you're cutting both white level and black level by the same amount, so the ratio between them stays the same no matter what.
