Conclusion: Optoma offers up a serious “premium” performance projector in the under $10,000 range, in the form of the HD8600 . Like every other projector we’ve reviewed, it has some strengths, and some shortcomings. This is one of those projectors, though that is mostly strengths. I have always been enamoured with the “look and feel” of DLP projectors, when done well. I’ve owned a few, and always been pleased, despite being one of the relatively few who are rainbow sensitive.
