Experience dynamic movie theater-like action, right here...
The HC7900DW home theater projector utilizes
Mitsubishi Electrics cutting-edge image-processing technologies to project beautiful,
exciting cinema-like images in the privacy of your own home.
Image reproduction has been refined for brighter,
sharper and clearer 3D viewing performance free from
phenomena such as crosstalk, judder and flicker.

The 3D experience can also be enjoyed using
commercially available 3D glasses.
*Some types of glasses may not work with this unit.
Please confirm compatibility at the retail store before purchase.
Wireless glasses cannot be used.
Minimal Flicker
Flicker when the screen is white has been
reduced through use of a 120Hz conversion
process in addition to that of the conventional
horizontal 96Hz display.

flicker cannot be applied simultaneously).
Reduction of "white flicker" that tends to appear in bright, white parts
Image showing "white flicker" effect
Thanks to motion-vector analysis technology, the position of a person
can be distinguished from the background and a moderate parallax
added to produce the sensation of depth used in 3D images. Unlike
simple 2D-to-3D conversion where the entire screen is shifted, 3D
images with a natural sensation of depth are reproduced, making it
possible to bring even classic films back to life in vivid 3D.
Positions of person and background are 3D image with
detected, and a moderate parallax is added natural depth sensation
The Latest Image Technologies Brought Together for Cinema-like Quality in 2D or 3D
New optical engine
with comprehensively improved contrast
and light leakage realizing high contrast of 150000:1
A variable iris is incorporated for optimal DLP pixel elements.
TM
Excellent black immersion is possible even when scenes change
instantaneously from light to dark. In addition to this, a fixed iris is
installed near the DMD chip. These features combine to further
improve contrast.

New Variable Iris
High 1500lm (Max.) luminance with clear, high-definition images
In addition to Variable Iris, a high-power lamp is adopted, providing both
enhanced image brightness and contrast. The high 1500-lumen (Max.)
brightness ensures that, in both 2D and 3D, high-resolution images are
clearer, sharper and more vivid than ever.
3D images reproduced in full high-definition with fine gradation
Equipped with two full 10-bit panel drivers (DDP3021)
PNX 5130 chip of FRC installed.
High-performance extra-low-dispersion lens for
full high-definition resolution (with V-lens shift)
Compared to commonly used glasslenses,
the projector is equipped with a high-performance
extra-low-dispersion (ED) lens system comprised
of a total of 13 lenses in four groups. Chromatic
aberration is minimized to the fullest and image
resolution is improved throughout, including the periphery.

Possible to set high-speed (6x) drive
As well as the conventional drive speed,
a high-speed (6x) drive can be set exclusively for
the 24P signal in 2D. This feature minimizes
the color breaking noise that is produced due to
color-wheel-based color separation methods.
FRC installed – Reproduce content supplemented with
optimal frame number
Applying motion-vector analysis technology, data from the previous
and succeeding images are used to produce highly accurate image
frames. The optimal number of frames is supplemented to match
the contents and the final image is reproduced. As a result, motion
blur in the vertical, horizontal and diagonal directions is suppressed.
True Video Mode
Blur is suppressed using video image motion interpolation.
New frames are created from previous and succeeding images.
True Film Mode
While retaining the clicking sensation unique to film, sharp clear images are projected.

the 24-frame film-like texture.

Color management function for easy fine-tuning of colors
The projector is equipped with a new color management function for
independent color R (red), G (green), B (blue), C (cyan), M (magenta)
and Y (yellow) adjustment of "Hue," "Saturation" and "Brightness." It is
also possible to adjust a specific color; when a color is selected only
the objects of that color are shown in color (others are in monotone),
making it possible to tune colors to preference more easily.
