What's more of a deal breaker to those in the market for a $100k projector, an extra $20-30k on the price or the lack of 4k? I mean we've already seen one person capable of purchasing this projector bow out due to the lack of 4k....
Or was it more or a technical issue than cost? Perhaps they couldn't guarantee the same pixel perfect alignment over 6 chips with 4k, even with their alignment tech? On that matter, is the alignment tech and/or the way of combining the two projectors in this way (low light and high light projectors) patented in any way? Is there anything stopping JVC or Sony from adapting their existing projectors easily (maybe even a software update!) to enable an option to do this when two of their projectors are present, say with two NX7/9's synced up that might potentially be able achieve most of the same performance for a fraction of the price?
Thank you as always for the in depth write ups and technical information, again, even if us mere mortals cannot afford it, doesn't make it any less fascinating to read.
Not at all a silly question
In short, technical issue.
At the time of developing the product there was no native 4K 3-Chip DLP DMD Chipset available to purchase from Texas Instruments. The only chip in existence at the time was the 1.43" Cinema chip, however this was unavailable due to still being within exclusive license agreement between TI and Christie, Barco, and NEC for exclusive use within their D-Cinema projectors.
Furthermore, the 0.67” 4M-Pixel-Shift DMD Single-Chip DLP chipset released by TI has comparatively very poor contrast performance as compared with the DarkChip HD 1080p DMD chipset used in the HDR DUO PLUS, meaning that there would have been a big drop in contrast, black levels, dynamic range, and HDR performance if SIM2 had used that chip; wherein, projectors using that chip are measuring only circa 800:1 native ON/OFF contrast, whereas this measures 8 times the performance of that.
What is really needed is a Native 4K resolution DarkChip 3-Chip DLP DMD, but as of today no such chipset exists.
So at the present time the CHRISTIE is the only native 4K resolution projector with very high contrast performance through the entire range 0-20% ADL wherein almost all video content resides.
BARCO has some new projectors in the pipeline that will be making use of another intriguing patented new technology, labelled 'Light Steering' technology wherein light is shifted away from the dark parts of the image to the bright parts thereby increasing the contrast and dynamic range. However, BARCO being BARCO the focus has been on using this technology to increase the top end, namely the brightness, as opposed to focusing on improving black levels. Furthermore, due to the way the technology works it is limited by how much light there is to move in the first place, in other words with very low ADL content it probably won't make much of an improvement. So for these two reasons I don't expect performance to achieve even close to what the SIM2 HDR DUO PLUS and CHRISTIE are able to achieve, but still hope to be pleasantly surprised as and when I see the next round of prototypes, which I hope will perform better than the earlier prototypes...
