this be my fourth projector and my second unit use a DLP chip . I can easily see rainbow in single chip dlp projector but this one almost completely eliminate they . I can still see a few rainbow , especially when there be bright object in a mostly dark scene , but it be hardly noticeable to I and none of my friend have be able to see they yet . if you be one of the few people who be bother by the rainbow effect , you may still want to demo this projector before purchase it online . I be originally use a gray screen in a light-controlled media room but the black with the darkchip3 be so good I move to a Stewart Filmscreen studiotek130 screenwall and the picture be spectacular . I recommend use a white screen with this unit . there be no gap between pixel or mirror dimple so the image be silky smooth . after calibrate with dve , the color be incredible . Colors pop , black be black and whites be white . Optoma have a zero dead pixel policy and a nice warranty . they also offer affordable -lrb- cheap , imo -rrb- extend warranty and upgrade service plan to meet you need . if you be in the market for a top-of-the-line single chip dlp projector , I honestly do not think you can get much better than this .
