The Meridian MF10 digital projector
offers extraordinary black reproduction
capability, with 30,000:1 native contrast
ratio. It also features a brand new 0.7in
full high definition device and associ-
ated optical engine utilising advanced
D-ILA technology. The impressive
contrast ratio is obtained via the native
capabilities of the engine, without the
use of a dynamic iris, thus ensuring
true black reproduction without loss of
brightness.
D-ILA is a particularly advanced approach
to LCOS (Liquid Crystal On Silicon) display
technology which offers significant advances
over other display systems.
Unlike many other systems, which use a
single display element and a colour wheel,
which introduces flickering and other
artefacts such as colour dithering and
rainbow effects, the MF10 employs three
individually-tuned 1920 x 1080 pixel D-ILA
devices – one each for red, green and blue.
D-ILA devices achieve a significant reduction
in stray light by flattening the spaces
between pixels and using new, advanced
liquid crystals and orientation technologies.
The optical engine also employs wire grid
polarisers, which signficantly reduce light
scatter into the projection lens, further
contributing to improved contrast.
In addition to a host of superb quality
features, each Meridian MF10 projector
is hand-tuned at our headquarters and
manufacturing facility near Cambridge,
England. Here, using specially-developed
test and calibration routines, we precisely
set gamma, colour temperature and
other parameters, allowing the MF10 to
dramatically exceed the performance of off-
the-shelf projectors.
Meridian has exclusive access to the inner
workings of D-ILA, and using special
software developed by William Phelps, we
are able to unlock the full potential of this
projector – particularly the ability to calibrate
the individual Red, Green and Blue colour
look-up tables (LUTs) that determine exact
colour levels for each pixel.
With full access to the projector’s processing
system, we can perform a full calibration
procedure, optimising not only gamma but
also colour/grey scale, ensuring more natural
colour and minimum artefacts. In addition,
we provide the highest degree of accuracy
with all available gamma selections. No other
company or process has access to these
capabilities.
Superior colour rendition is made possible
by an unusually broad colour space – the
MF’s colour rendering system exceeds the
gamut of competing systems (see over).

The standard motorised projection lens is a
large-diameter all-glass assembly with 16
elements in 13 groups. It is made by Fujinon
Corporation, noted for their quality projection
lenses. The lens minimises chromatic
aberration effects and delivers maximum
resolution by ensuring that individual pixels
areallinfocuson-screen.The2xzoom
capability permits a large, bright image even
in smaller environments that do not allow for
longer projector-to-screen distances.
The projector also includes a special vertical
stretch facility for the display of extra-wide-
screen images with the addition of a third-
party lens assembly. Most projectors obtain a
2.35:1aspectratiosimplybymaskingoffthe
top and bottom of the display area with black
bands (letterboxing). This inevitably reduces
the image resolution, brightness and contrast,
as a significant number of available
display pixels are not being used. In the case
of the MF10, the image is expanded vertically
to facilitate the use of all 2,073,600 pixels
in the display engine, dramatically increasing
brightness and contrast.
To make positioning of the projector in an
installation as easy as possible, the MF10
offers±80%verticaland±34%horizontal
lens shift, and the unit may be table or
ceiling mounted. Ease of installation is
further enhanced by the front intake/exhaust
arrangement of the low-noise fan system,
which leaves only interconnects on the rear
panel. In addition, the lamp is easily accessed
via a side panel wherever the projector is
mounted.
The projector features HDMI 1.3 inputs,
allowing225MHzbandwidthandbillions
of colours, enhanced resolution and higher
frame rates. The connectors are widely-
spaced to allow the easy connection of
professional cabling. The multiple input
capability of the MF10 makes it particularly
easy to install in a wide variety of systems.
AMeridianDVDplayerlikethoseinthe
800 or G Series can drive the MF10 directly
via HDMI, and there are also component,
S-Videoandcompositeanalogueinputs.
