70,000:1 native contrast ratio is achieved
The newly developed optical engine features a new wire grid and a
redesigned aperture that reduce excess light leakage to negligible
levels, making possible a remarkable 70,000:1 native contrast ratio.
High contrast and film-like quality offered by the original D-ILA devices
also help to ensure smoother grayscale, truer black levels and more
depth.

New Color Management System with 7-axis matrix
In addition to the ordinary 6-axis matrix of red, green, blue, cyan, magenta,
and yellow, the new Color Management System features a seventh matrix
of orange to ensure the precise adjustment of hue, saturation, and intensity.
The addition of the orange axis also helps in enhancing the selection of the
color spectrum for skin tones. And for improved operability, only the color
being adjusted will be shown on the screen while the others are displayed
in black and white.
JVC original Film Tone
Until now, attempting to correct brightness or contrast settings as
desired caused black or white levels to shift incorrectly with each setting.
In order to overcome this issue, JVC has developed an original Film
Tone function, which works to balance gamma, contrast, and brightness
settings without affecting the gray scaling of the source to enable
brightness adjustment that better matches the ambient environment.

Darkness and lightness correction
Adjustment of gray level, another essential factor for creating high-
quality images, can be corrected by separating darkness and lightness
levels. By enabling darkness and lightness correction, the desired levels
of gradation can be achieved without the tedious gamma correction
process of conventional models.

Adobe RGB for a wider color reproduction spectrum
The new optical engine achieves a greater expansion of the color
spectrum by employing an innovative color filter. This results in a full-
spectrum of color reproduction with complete coverage of different
color spaces such as Adobe RGB, DCI, and HDMI with a 20%*
increase in the color reproduction spectrum compared to conventional
JVC projector models. With this
increase in color space, the new
optical engine can more vividly
reproduce colors such as the
green of trees, the blue of oceans,
etc., which were difficult to
recreate accurately up until now.

New screen adjustment modes*
JVC has focused on individual screen characteristics to ensure the faithful
reproduction of film-like picture quality. By improving upon the screen
correction modes found on conventional models, these new screen adjustment
modes analyze the RGB reflective characteristics of the screen being used to
achieve optimum correction. The user can select an optimal parameter from a
set of 94 parameters for an outstanding picture with natural color balance.
*Please refer to the JVC website for the comparison table of primary screens and adjustment modes.

THX 3D Display Certification
The JVC DLA-X7 is the world's first projector to be accredited for the
THX 3D Certification. During the THX 3D Certification process, more
than 400 laboratory tests are conducted, evaluating projector's color
accuracy, cross-talk, viewing angles and video processing to ensure
the high quality 3D and 2D display performance that home theater
enthusiasts demand today. Featuring THX Cinema Mode, this
projector has a simple, one button solution for optimized playback
of 3D and 2D movies on Blu-ray Disc and broadcast TV. Additionally,
the projector can be professionally calibrated by trained dealers to
the user's choice of screen surfaces in the THX Mode.

Certified by ISF (Imaging Science Foundation)
The DLA-X7 projector has been licensed with the ISF C
Calibration Controls) mode, enabling trained dealers to professionally
calibrate it to your choices of screen surface, lighting environments
and video sources and then securely store precision settings into the
projector. This helps to ensure reproduction of film or video content
accurate to the source and excellent picture quality optimized for
specific environments.
