4K Native and 8K/e-shift Projection
8K Home Theatre Projection Achieved by Combining Native 4K and "e-shift" Technology
"E-shift" is JVC’s proprietary high-resolution display technology that shifts a pixel by 0.5 pixels vertically and horizontally to achieve 4 times the pixel density of the original content. The 8K/e-shift technology adopted for the DLA-NX9 combines "e-shift" technology with another proprietary technology, Multi Pixel Control, to convert Full HD and 4K-resolution images into 8K-equivalent resolution (8192 horizontal by 4320 vertical). The result is an eyeopening, high-definition display that is very close to the original subject*1.
*1: The projector does not support 8K signal input.
Frame Adapt HDR function
The Frame Adapt HDR function* enables reproduction of any HDR10 content dynamically and in high-resolution!
The colour grading of HDR content varies, some HDR content are adjusted to bright side and others to the dark side. Using JVC’s original algorithm, Frame Adapt HDR instantly analyses the peak brightness in HDR10 content frame-by-frame and in real time adjusts the projector to the optimum dynamic range. What’s more, the gamma processing accuracy of gradation performance has been improved dramatically from, 12-bit to 18-bit.
All these advancements help to bring out deeper blacks in darker scenes, and higher peaks in brighter scenes without losing colours. Reproducing images with smooth gradations, that are closer to reality as seen by the human eye. (*from firmware version 3.10 and higher)
In the picture, scene 1 represents a dark scene, scene 2 a bright scene and scene 3 a combination of bright and dark.
High quality, all glass lens
The DLA-NX9 is equipped with an 18-element, 16-group all-glass lens featuring a full aluminium lens barrel. In order to project high-resolution images to every corner of the screen with the 100 mm diameter lens offering wide lens shift of ±100% vertically and ±43% horizontally, the projector adopts five ED lenses that take into account differences in the R/G/B refractive index to reduce chromatic aberration and colour fringing when lens shift kicks in to deliver precise reproduction of 8K-resolution projection. The DLA-N7 and DLA-N5 models feature a 17-element, 15-group all glass lens with 65 mm diameter to project fully focused 4K native resolution to all corners of the screen.
High Dynamic Range (HDR)
HDR (high dynamic range) content contains more data including an extended brightness range, 10-bit gradation and a wide BT.2020 colour gamut. For this reason, high basic performance is required for precise reproduction by the projector. With D-ILA projectors, HDR content are optimally reproduced with “high-brightness, high contrast, and wide gamut” to enjoy high quality HDR content as you’ve never experienced in the past. Moreover, in addition to HDR10 content, which is found on UHD Blu-ray Discs, the projector automatically detects the Hybrid Log-Gamma (HLG) signal, a technology used widely in broadcasting, allowing the user to view it in an optimum picture mode.
Auto Tone Mapping
The Auto Tone Mapping function featured on the latest models automatically adjusts each content based on the values in the mastering data, such as Max CLL and Max FALL*6, which indicate the brightness of the HDR content. Image quality is automatically adjusted for optimal viewing of various HDR images with different brightness.
*5: Content without mastering info is set at fixed level or can be adjusted manually.
*6: Max CLL (stands for Maximum Content Light Level); Max FALL (stands for Maximum Frame Average Light Level)
Brighter, High Contrast, Wide Gamut
High-quality, Clear Picture with Brightness
Maximum brightness of 2,200 lm*2 can be achieved by combining a 265 W ultra high-pressure mercury lamp and a highly efficient optical engine. *2: Achieved on the DLA-NX9.
Images Full of Presence with D-ILA’s High Contrast
JVC’s original D-ILA device combined with an optical engine equipped with a wire grid results in a high native contrast ratio of 100,000:1*3. Combined with Intelligent Lens Aperture, a dynamic contrast ratio of 1,000,000:1 can be achieved*3. *3: Figures for the DLA-NX9.
Vivid Images through a Wide Range of Colours
By using a new cinema filter, the projector achieves not only 100% coverage of the BT.709 but also coverage beyond the DCI-P3*4 display range used in film production. The wide color gamut ensures a more accurate reproduction of HDR content and natural gradations. *4: DLA-NX9 and DLA-N7.
