hi guys,
i am new to this forum, but have been an owner of CRT-projectors for over 20 years now, and i promised myself that, next time i buy a front-projector, it will be something other than a CRT,as, let's face it, that is a technology that has reached its peak in performance and price (SONY, RUNCO,VIDIKRON,etc), and it is time to "go digital", so to speak...
like a lot of other people, i have been waiting for DLP,LCD and/or D-ILA technologies to catch-up to CRT's in contrast, color and resolution, but keeping the brightness, reliability, easy of set-up and pricing, that these newer technologies have been known for, and it seems to me that finally there is a "light and the end of the tunnel", with the recent introduction of the SHARP XV-Z9000U and the, supposedly, upcoming SELECO HT-300.
however, i have a few questions :
to owners of DLP projectors, could you once and for all tell us about the reliability of those DMD-chips ??? do they suffer from "dead-pixels",like LCD's do?? i guess in their case, they should be more appropriately called "dead-DMD-chips", as in DMD-chips that fail to operate properly after some time of use, or that came from the factory already "stuck"...and while we are on the subject, what about "dust-blobs" and pollution contamination on their optics? is it as bad as on LCD front projectors???
also, what is the deal with this new TEXAS INSTRUMENTS (TI) DM3 chip? is it the one that some people refer to as the "black-chip",with a built-in layer of some black material right on the chip, for better contrast?
and what about this new press release from TI,dated 6/7/2001 titled "SEQUENTIAL COLOR RECAPTURE and DYNAMIC FILTERING",in which it is described a major improvement in single panel DLP system... "SCR, a technology that allows all three primary colors (RGB) to be present simultaneously in a single panel DLP system such that it can be as efficient as, or potentially more so, than a three panel system, but without the additional parts, size, weight and cost. images can be up to 40% brighter than is currently possible,as well as increased color saturation"...WELL, WOW...!!
oh well, perhaps i am going to have to wait for another year, untill finally everything falls into place, as in a single panel DLP front-projector that comes with this new "SCR" technology, 1280x720 DMD-chip(or higher!),a SEALED "light-engine" to prevent dust and pollution contamination (like the SELECO HT-250),and the new SAGE/FAROUDJA "DIAGONAL DECORRELATION DEINTERLACING" chip (DCDi) built-in, for top-of the line 3/2 pulldown film deinterlacing ---motion detection line doubling from video sources --- pixel by pixel interpolation... and, best of all, quite inexpensive for all it does !!!
any thougths on this posting, guys??? thanks.....
