If this is the case that they are doing is pretty simply I don't think anything too complex, basically:
subpixel1 wheel rotation 1: half of R, W, G, half of blue
subpixel2 wheel rotation 1: other half of blue, W, G, other half of red
subpixel3 wheel rotation 2: half of R, W, G, half of blue
subpixel4 wheel rotation 2: other half of blue, W, G, other half of red
they could also do this for a 0.66" xpr dmd in the below manner to get 5x wheel speed:
subpixel1 wheel rotation 1: half of R, Y, G, half of blue
subpixel2 wheel rotation 1: half of blue, Y, G, half of R
My main question is, for us technically minded folks why don't they put the correct specs and diagrams on their websites? I've actually corrected BenQ a couple of times for wrong info on their website in the past year, this would be a really large marketing error to not capitalize on the fact they are using a faster sequential color speed than some competitiors.
Its also too bad its basically impossible for highly interested folks like myself to evaluate their new reference projectors (HT9060/LK990) as none of the dealers near me carry them to demo. A lot of this stuff could be put to bed really easily with a comprehensive test, including things like very fast shutter speed photography to capture sequential color speed. Its a pretty large marketing blunder to think that people will spend $6000-$9000 on their top projectors, sight unseen, just based on their webpages and mainstream review sites which regularly fail to convey the whole story and cover all the nuances. I would love to do a comparison myself but 15 grand on projectors just to compare isn't pocket change.
It’s very possible. Although I can’t say for sure as I’ve never inquired about business projectors or projectors in that price class.
Besides contrast specs, which we all agree are total fabrication, I don’t think any of the manufacturers are attempting to deceive. Well... maybe JVC in the first few years of E-Shift. But this color wheel question is a complex subject that would be nearly impossible to adequately explain in a spec sheet. Benq, to their credit, does list this information for the HT3550 on their website:
As far as not being able to see/experience high end gear— that’s been an industry wide problem with a lot of brands not just projector manufacturers. While it’s not even in the same discussion as the models you mentioned, benQ is planning a big push for the HT5550. They’ll actually be demonstrating one at an event later this month in New York. I was a bit surprised as this is a dealer only model— much to many member’s chagrin. I know the HT9060 is coming as well but all I know about that model is Chris Eberle of Secrets has one and his initial impressions were very positive (review still isn’t published).
