JVC introduced on the first day of CEDIA Expo a new projector lineup equipped with JVC’s latest laser light technology first introduced in its flagship RS4500 model.

These are also positioned as some of the first 8K projectors to support the HDR10+ dynamic metadata HDR profile.

The 2021 line is highlighted with three models boasting the company’s advanced laser light technology, and are said to be the world’s first projectors to offer 48Gbps 8K HDMI inputs for up to 4K/120fps performance.

The company said the new laser projectors feature new LSIs and JVC’s proprietary 8K/e-shift technology (called 8K e-shiftX for the top two series in this iteration) that enables the input and display of near 8K ultra high-definition images, while JVC’s BLU-Escent laser light source reproduces images with greater precision and dynamic range on large screens.

The three new JVC laser projectors are available in both the company’s Procision Series and Reference Series lines. These include the Procision Series DLA-NZ9, DLA-NZ8, and DLA-NZ7, and the Reference Series DLA-RS4100, DLA-RS3100, and the DLA-RS2100. Model performance virtually matches from series to series.

Product Model Color MSRP Availability
D-ILA Projector DLA/NZ9/DLA-RS4100 Black $24,999.95 October
D-ILA Projector DLA-NZ8/DLA-RS3100 Black $14,999.95 October
D-ILA Projector DLA-NZ7/DLA-RS2100 Black $9,999.95 October

With the new BLU-Escent light engine, the lineup significantly ups the brightness ante from the previous DLA-NX and RS projector series, along with support for 8K60p/4K120p resolution input using a new LSI. JVC has employed its proprietary 8K/e-shiftX technology in the top two series to scale native 8K sources. This technology achieves resolution close to native 8K by shifting pixels in four directions rather than two, as in the earlier version of e-shift.

The top-of-the-line DLA-NZ9/RS4100 models are equipped with a premium 100mm diameter all-glass lens, Ultra-High Contrast Optics for advanced contrast, and 8K e-shiftX. The DLA-NZ8/RS3100 models have many of the same features as the NZ9/RS4100, but with a 65mm diameter all-glass lens. The DLA-NZ7/RS2100 is positioned as a value model, offering a laser light source, 8K input, and step-down 8K/e-shift at what the company calls “breakthrough pricing.”

Key features include the following:

All models include 48Gbps 8K60p/4K120p inputs. These are dual 48Gbps HDMI inputs with HDCP 2.3 to ensure “future proof connectivity” and will support high action game play for the latest advanced gaming consoles.

JVC said the new 8K/e-shiftX system delivers resolution that appears close to 8K native resolution in the DLA-NZ9/RS4100 and DLA-NZ8/RS3100 models.

The company uses an improved version of its 0.69-inch native 4K D-ILA microdisplay device. The original 8K/e-shift technology doubled resolution by shifting one pixel diagonally by 0.5 pixels. The new 8K/e-shiftX, used in the two top series, uses a 240Hz driver to shift in four diagonal directions (up, down, left, and right). The result is the ability to display 8K content with pixel perfect 8K resolution, JVC said.

The new LSI for 8K60p/4K120p input and video processing provides for instantaneous processing of an enormous amount of information from 8K input to device output. The new LSIs are said to ensure “stable and high picture quality.”

The new projectors also support 4K120p input, which is expected to become more commonly available in the near future. This will make the projectors “highly effective in displaying high frame rate gaming content,” JVC said.

The 0.69-inch native 4K D-ILA device with improved drive performance shifts the image in four directions (up, down, left, and right). JVC said this is necessary to drive the panel at twice the speed of conventional systems. To achieve this, the D-ILA drive device now displays images at a speed equivalent to 240Hz, while achieving a native contrast ratio of 100,000:1, JVC said. Top performing models equipped with a laser light source achieve a dynamic contrast of ∞:1, according to JVC, as a result of a combining in a dynamic light source control that automatically controls output.

The DLA-NZ9/RS4100 is equipped with a 16-group, 18-element, all-glass, all-aluminum barrel lens. The 100mm diameter lens has a wide shift range of 100% up/down and 43% left/right, and uses five special low-dispersion lenses supporting refractive indices between R, G, and B to project high resolution to every corner of the screen.

Other models feature a 65mm diameter all-glass lens with 17 elements in 15 groups to deliver high-resolution images that are in focus all the way to the periphery of the screen, JVC added.

The BLU-Escent laser light source technology has a reflective phosphor wheel and not a transmissive one. This is said to achieve both high brightness of 3000 lumens (just under 1,000 nits) in the top performing models and an estimated life of approximately 20,000 hours. The technology uses a blue laser diode as the light source providing high brightness and longevity. JVC said the increased brightness makes it compatible with larger screens and significantly increases the peak brightness during HDR playback.

Peak brightness levels of the DLA-NZ8/RS3100 models is 2,500 lumens (730 nits) and for the DLA-NZ7/RS210 it is 2,200 lumens.

The laser diode allows instantaneous control of light output, enabling dynamic brightness adjustment with less delay compared to conventional mechanical apertures, the company said.

“By controlling the laser output according to the brightness of the video scene, it is possible to reproduce images closer to human perception. In addition, ∞:1 contrast is achieved by controlling the output of the laser during hide, signal discrimination, etc,” the announcement said.

For High Dynamic Range (HDR), JVC has added support of the HDR10+ format, which, like the not-supported Dolby Vision profile, is based on dynamic metadata. The projectors also support the baseline (static metadata) HDR10 profile and the Hybrid Log Gamma (HLG) profile used in live HDR broadcasts.

HDR10+ embeds luminance information for each scene in the content as metadata, so tone mapping can be performed according to the scene. This makes it possible to faithfully reproduce the HDR images intended by the creators, JVC said. By comparison, HDR10, the basic standard for HDR playback, has only two pieces of information: MaxCLL (Maximum Content Light Level), which represents the maximum brightness of the content, and MaxFALL (Maximum Frame Average Light Level), which represents the average maximum brightness.

JVC uses its proprietary Frame Adapt HDR and Theater Optimizer. The former performs dynamic tone mapping — either frame by frame, or scene by scene — based on analysis of HDR10 content, while the latter automatically performs optimal tone mapping according to the installation environment.

Eighteen-bit level gamma processing suppresses tonal gradations in bright areas and blacks in dark areas, and reproduces smooth gradations with high accuracy. Together, these two unique features deliver the best possible HDR image.

Ultra-High Contrast Optics further improves the quality of projected images in the DLA-NZ9/RS4100 and DLA-NZ8/RS3100 models while achieving significantly higher brightness by adopting a more efficient polarization method. The new optical device thoroughly eliminates internal unwanted light “to significantly improve the quality of projected images.”

JVC has also improved its prism polarization method to increase light output. JVC said the G (green) light component, which contributes to optical brightness, can now be used more effectively, resulting in an increase in optical efficiency of approximately 10%.

A cinema filter is said to deliver vivid color images with 100% DCI-P3 wide color gamut coverage.

For motion clarity, JVC has improved the accuracy of its proprietary Clear Motion Drive image blur reduction technology at object boundaries by reviewing the interpolation algorithm. In combination with Motion Enhance, which optimizes the drive of the D-ILA device according to the movement of the image, this technology reproduces 4K images more smoothly, JVC said.

Other Features in the new models are the following:

· All models are ISF-certified and can be color-calibrated by ISF-certified engineers.
· The Installation Settings function allows up to 10 types of installation adjustments to be saved and easily recalled. These include lens memory, pixel adjustment, and screen masks. Screen size and gain, and aspect ratios can also be set.
· The auto-calibration function is provided to optimize the optical characteristics that vary depending on installation and usage conditions.
· The Screen Correction Mode corrects color imbalance caused by screen characteristics.
· Rear air intake and front air exhaust design for various installation environments, such as installations close to a wall.
