Thanks for the report, Seegs108. For the record -- I think that's my photo you linked to above and to be fair: it had its contrast drastically boosted to show the striations. It only shows up in brighter scenes with less detail (sky,...

Quote:Originally Posted by BobL Yes the further throw is not applicable to most retro screens but they still suffer other problems. Actually, the general principle for retro-reflective is to have it as close to the viewer as...

Quote:Originally Posted by BobL All gain screens are susceptible to hot spots some worse than others. In general the further the throw the better. I don't think this is true for retro-reflective screens that send most light...

Quote:Originally Posted by hifiaudio2 Nice schematic. However, I was told there would be no math. Ha Nice home theater build, btw. Suppose I should mention the other possibilites of DFI that would not lead to the same loss in...

Thanks Mark, & Kelvin. Agreed. Most everyone would benefit from a higher contrast projector. Just not if you're watching with a ton of ambient light in a white room with a huge matte white screen close to white walls/ceilings... where...

Quote:Originally Posted by HoustonHoyaFan IIRC this is exactly what how DFI on the Sony is implemented. It is very similar to a film projector (remember those) running at 24p where the aperture is opened twice per frame. Yes some...

I drew up a little schematic of how I think DFI should work; here it is as a PDF: http://cl.ly/MQB9 I believe the HW30/50 & VW95 are all using (2) in my schematic; namely, 96Hz processing with 48Hz flicker (frame doubling, then...
