Quick note: the DLP470TE (.47 4X shift) and DLP660TE (.66 2X shift) also have the same 5.4 micron pitch and 17 degree +/- tilt angle as part of TI’s new TRP pixel architecture. The .47 1080p DMd is also a TRP chipset. The older .65 1080p DC3 used in some of the more popular 1080p models (like the Ht2050A) uses a larger pixel pitch combined with a shallower tilt angle.
While I’m sure the light frame was not helping with contrast/blacks, according to BenQ it wasn’t a direct cause for the poor contrast of those first generation DLP470TE 4K projectors.
From what I understand the Ht3550 and HT5550’s improvement in contrast comes down to three things: an optimized light path with all glass optics that absorb and reflect less light, the dynamic iris and, perhaps the unsung hero, improved HDR tone and gamut mapping.
Any word on a 4K .95 chip? I loved the sharpness on my old W5000 that the .95 chip produced.
