Bonjour,
Les infos préliminaires concernant la nouvelle série de projecteur JVC X7500 (& X9500) amenés à remplacer la série JVC X7000 & X9000 peuvent être consultées ici (en Japonais...) :

"JVC Kenwood will release JVC brand home theater projectors "DLA - X 770 R" and "DLA - X 570 R" compatible with 4 K / 60 p video input and HDR signal Hybrid Log - Gamma (HLG) system in late December. The price is 900,000 yen for X770R, 700,000 yen for X570R. The color is X770R black (B), X570R two colors of black (B) and white (W).
DLA-X770R
The panel is a D-ILA projector which realizes 4K display by combining 0.7 type and Full HD D-ILA device of 1,920 × 1,080 dots, "pixel shift" technology "e-shift" technology. Compared to the '15 year model' DLA-X 750 R 'and' DLA-X 550 R ', it improves brightness and contrast, it supports HLG for HDR picture quality broadcasting, and switches automatically when HDR 10 signal is input It is a big feature that adopted "HDR auto picture mode".
The main difference between the two models is brightness and contrast ratio, as well as the higher model DLA-X770R acquired THX 3D display standard certification. It also has its own "Real Color Imaging Technology" to realize "film quality" faithful to original images.
Supports full-spec 4K video input compatible with 18 Gbps transmission band such as 4K / 60p 4: 4: 4 signal, 4K / 60p 4: 2: 2/36 bit, 4K / 24p 4: 4: 4/36 bit. It also supports HDCP 2.2.
With the 265 W high-pressure mercury lamp and a high efficiency optical engine, the X770R has a high luminance of 1,900 lumens (the conventional model X 750 R is 1,800 lumens). Combined with D - ILA device with narrow pixel gap and high light utilization efficiency, it realizes a precise, smooth, and powerful image. It is said that you can enjoy clear and powerful 4K images.
The X570R also carries a 265 W high pressure mercury lamp, but its brightness is 1,800 lumens.
Moreover, the X770R improved the native contrast ratio from 120,000: 1 of the conventional model to 130,000: 1 by the D - ILA device and the optical engine adopting the wire grid corresponding to the high power lamp. In addition, it has "intelligent lens aperture" which analyzes the input image by its own algorithm and automatically controls the black level, and the dynamic contrast is strengthened to 1.3 million: 1 (conventional model is 1.2 million: 1). The X570R has a native contrast ratio of 40,000: 1 and a dynamic contrast of 400,000: 1.
Following the conventional model, it supports HDR video input such as UHD Blu-ray. Utilizing high native contrast, HDR content is faithfully reproducible.
Newly supports "HLG" adopted for 4K broadcast by SKY Perfect and Hikari TV, and "HDR auto picture mode" which automatically switches when HDR 10 signal is input is installed. Depending on the type of signal, it may not be switched automatically.
Also equipped with original video processing technology "Multiple Pixel Control". The new analysis algorithm adopted in the flagship model "DLA-Z1" is also adopted in the X770R / X570R. Not only 4K video but also full HD video can be converted to higher definition 4K video and expressed. Compared with conventional band processing, image detection with emphasis on higher bands ensures both sense of refinement and blurring, realizing the reality unique to 4K.
In addition, a low delay mode optimum for games etc. is also newly installed. In the same mode it reduces the display delay of PC signals and games and boosts response performance to quick operation.
As a moving picture processing technology, we will equip the "Clear Motion Drive" of moving picture interpolation corresponding also to 4K / 60p 4: 4: 4 and "Motion Enhance" controlling the driving of the D - ILA device according to the picture. It has a "pixel adjustment function" that allows delicate adjustment in units of 1/16 pixel, and it can store 2 memories. Equipped with 6 axis adjustment color management.
In addition, an auto calibration function that optimizes the image quality that varies depending on installation conditions etc. can also be used. For automatic calibration, commercially available optical sensors and dedicated software, PC, Ethernet cable are required.
Projection size is 60 to 200 type. 2x zoom lens (F3.2 ~ 4). Zoom and focus are electric. It corresponds also to the lens shift of ± 80% up and down, ± 34% right and left. A new correspondence screen has been added to "screen correction mode" which corrects color imbalance caused by the characteristics of the screen to be used.
It has two HDMI inputs and supports 3D, Deep Color, HDCP 2.2. In 3D playback, 1,920 × 1,080 dots are displayed. 3D synchro output, trigger output, RS - 232C, Ethernet etc are equipped. Fan noise is 21 dB (lamp mode: low). Power consumption is 380 W (standby time 1.5 W, eco mode standby time 0.4 W), external dimensions are common for 455 × 472 × 179 mm (width × depth × height). Weight is 15.6 kg (X 770 R) / 15.4 kg (X 570 R). The X770R also has a lens cover."
et à la lecture on peut constater qu'il n'y a aucune révolution du style inclusion d'une matrice UHD/4K, dans cette nouvelle série X7500 (1X9500). Celles-ci correspondant en fait à une évolution des séries X7000 & X9000 précédentes et dont il faudra attendre l'annonce officielle JVC afin d'en connaître les détails précis.
La présentation officielle par JVC de ces nouveaux projecteurs aura lieu au CES de Las Vegas début Janvier 2017. (Edit Hugo 23 Déc)
