Bicheando por AVSF me he encontrado con una review de este bicho, bastante interesante salvo por el precio. A ver si os parece a la altura de los cacharros que se manejan por aquí:cuniao

NEW CHRISTIE HIGH CONTRAST 4K HDR RGB LASER PROJECTOR REVIEW
SUMMARY:
Not only is this without a shadow of a doubt the best video projector in the world, this is quite literally the best video image performance that I have ever seen in my life to date. Period. End of story. Goodbye. The End.
It significantly outperforms not only all other projectors, but also all other video display devices that I can think of with respect to overall video performance, across all formats, from televisions (whether OLED, LED LCD, MicroLED or otherwise) to modular emissive video walls.
In my opinion, this is the new video reference gold standard against which all other video displays should now be compared. It is quite literally the ultimate video display and with it Christie has set a benchmark of near insurmountable Everest proportions.
MEASUREMENTS:
CONTRAST:
ON/OFF contrast and ANSI contrast by no means tell you the whole picture as far as contrast performance of video content is concerned. Why? Because neither ON/OFF nor ANSI are in fact directly applicable with respect to actual video content. ON/OFF contrast and ANSI contrast are the two extremes of the contrast range that relates to video content. The ON/OFF Contrast only gives you the black level on a completely black picture. Whilst this is useful with respect to obtaining and comparing what is best black level performance capability of the particular display device, this does not tell us what is the typical contrast and/or black level performance for the majority of actual video content. Similarly, the ANSI Contrast only gives you the black level at what is typically the extreme upper limit of video content brightness. Hence, typically over 99% of video content falls within these.
Consequently, in order to gain a proper understanding and to be able to properly assess and evaluate what is the comparative contrast and associated black levels performances regarding different display devices we really need to be taking measurements with respect to the contrast performance in-between the ON/OFF and ANSI contrast; namely the full range of ADL (Average Display Level) contrast.
Where ADL is defined as being the average on-screen brightness after gamma correction; and the ON/OFF contrast corresponds to an ADL of 0%, and the ANSI contrast corresponds to an ADL of 50%.
The following contrast measurements were taken at actual usage light output levels:
NATIVE ON/OFF CONTRAST = 21,150,500:1
1% ADL = 83,649:1
2% ADL = 44,545:1
3% ADL = 34,730:1
4% ADL = 19,461:1
5% ADL = 15,452:1
10% ADL = 8,228:1
20% ADL = 3,771:1
ANSI CONTRAST = 1,035:1

LUMINANCE:
● PEAK LIGHT OUTPUT = 30,000 LUMENS
● 5.365m / 17’ 7” WIDE 0.9 - 1.0 GAIN SCREEN , WITH CIRCA 16,500 LUMENS LIGHT OUTPUT:
- WHITE LEVEL = 440 NITS
- BLACK LEVEL = 0.00002 NITS
GAMUT COVERAGE:
● %AGE OF BT.2020 COLOR GAMUT = 92.2%
- Both the RED and BLUE are beyond BT.2020; with the GREEN falling slightly short:

PHOTOGRAPHS / SCREENSHOTS:
All of the photos have been taken using a professional photography calibrated flagship Nikon camera, in HDR, as unprocessed and unedited raw images, accurately capturing the actual projected image black level, with the white balance precisely matched to the projection screen. Hence, with respect to these aspects, in addition to the image sharpness and detail delineation, the photos are accurately representative of what the projected images look like in person.
However, despite using HDR photography, the magnitude of the luminance dynamic range of this projector is so incredibly large that it was impossible to capture the full extent of this; and also similarly the chroma (color) gamut coverage of the projector is very considerably wider, deeper, and greater than the capabilities of the camera. Hence, with respect to these aspects the photos are by no means even close to what the projector looks like in person in these regards; where the only way to see what are their actual respective performances is to view the projector in person.
(N.B. in order to view the images with the best accuracy this is best done via a calibrated video display)
*** If viewing this using your a mobile device you can simply zoom in with respect to the photos to see them in their full high resolution; or alternatively to view and/or grab the full size photos simply right click on whichever image and select VIEW IMAGE from the menu window. You can also then left click to zoom in and view the image in 1:1 ratio ***

MISCELLANEOUS INFORMATION:
● Model name / number to be confirmed.
● The projector is available in a variety of iterations, from 2 laser modules (= 5,000 lumens) to 12 laser modules (= 30,000 lumens); with each laser module providing circa 2,500 lumens of light output. Pricing varies accordingly; from the 2 module option being the cheapest to the 12 module option being the most expensive. Being the top of the top of the pyramid of flagship high-end video projection, as expected, all MSRPs / RRPs will be ‘six figures’.
● There is only a very small few percentage light loss post-calibration, because out-of-the-box the projector is already very close to D65 white point.
● Speckle is a non-issue. With unity gain screen there is absolutely no perceivable speckle whatsoever; hence, there is absolutely no need to any anti-speckle systems / solutions. The manifestation of speckle has been minimized as a consequence of utilizing multiple different wavelengths of laser diodes for each of the red, green, and blue, in conjunction with avoiding usage of a high gain projection screen material.
● Black levels are so black that there is absolutely no need whatsoever for any masking of black bars; and you literally cannot see where is the divide between the edge of the projected image where there is black and the outside of the projected image where there is no light being projected at all.
● The world-record-breaking projected contrast and black levels performance has been achieved via use of the same patented technology that features within the Dolby Cinema projectors; which is akin to the Full Array Local Dimming (FALD) that some LED LCD TVs utilize. Where, with respect to this projector, there numbers 2,073,600 dimming zones.
● Color depth: 12-bit
● Does not currently support consumer Dolby Vision.
** HOWEVER ** it is most certainly technically possible for Christie to add this at some point in the future, and probably simply via a firmware update. Although, I must stress that at the present time Christie has not and is not yet committed to adding this. But it is most certainly technically possible if Christie decides that it is something worth doing.
● Supports 4K60 with low latency.
● OPTIONAL UPGRADES (with associated one-off additional costs):
- “Mirage” upgrade (via firmware update) adds both High Frame Rate (HFR) 4K120 support and active 3D functionality, with 4K60 into each eye.
- Multi-Point-Of-View for gaming – up to 4 number active glasses, each perceiving different full sized images, which are 2K60 each. Support for 4K30 might also be added.
● No external chiller required; only environmental climate control / cooling
● Multiple lens options covering a wide array of throw distances versus screen sizes
● 3-year warranty.
● Shipping / availability commencing 2nd quarter 2019.
