DPI's dVision Scope Stretches 1080 Resolution

Digital Projection International
(DPI) traveled to CEDIA Expo to present a new twist
for natively handling 2:35:1 aspect ratio material
without a losing resolution or introducing distortion
to 1080p material.
The projector, which features 2.75 million pixels
when scope HD content is displayed, is listed as
providing 2560-by-1080 resolution to deliver a true
1080p solution for 2:35 aspect content without optical
stretching, and without the need for an anamorphic
Michael Bridwell, Digital Projection marketing
director, said that despite announcements of competitors’
4K solutions, DPI sees projectors with highquality,
easy-to-use 2:35 aspect ratio solutions as
meeting a true market need.
“The most interesting thing to us right now is the
2,560 by 1,600 [DLP] chip that’s able to take our dVision
scope, and that’s native aspect ratio shifted. It is
a truly functional application for the residential market
right now,” Bridwell told TWICE. “What you do is use
a custom integrator to dampen the extra pixels leaving
2,560 by 1080p. So when it senses a change in
aspect ratio content, you don’t need an extra lens off
The company said the dVision Scope 1080p uses
a combination of horizontal resolution and intuitive
input analyzing firmware for an anamorphic-lens-free
full-resolution constant height widescreen image.
The single-chip dVision Scope 1080p attains a
pixel density with more resolution detail and higher
small area contrast than previously thought possible.
The greater pixel numbers avoids optical stretching
to achieve the 2:35:1 aspect ratio.
Another benefit is the ability to maintain a constant
height image while moving between 1.78:1 and
2.35:1 aspect ratio content (or any content wider
than 1.78) without an anamorphic lens.
In addition, anamorphic optics reduces a projector’s
brightness and contrast performance, DPI said.
Bypassing the need for such a lens also presents a
more cost effective alternative.
When 1.78 content is being viewed, the dVision
projector presents that content at native 1080p resolution.
When wider aspect ratio content is presented, the
wider content continues to be displayed at 1080 pixels
of vertical resolution, so the vertical height of the
image is maintained.
Horizontally, the image is resized to as much as
2,560 pixels, depending on the aspect ratio of the
source being displayed. The projector’s aspect ratio
is thus adjusted so that the wider content is presented
with increased horizontal resolution (beyond the
1920 horizontal pixels associated with 1080p content).
Specifically, when scope content is presented,
the projector automatically detects the presence of
the “letterbox” black bars within the signal, and immediately
resizes the image to fill the height of the DMD
(1080p) while also presenting the proper aspect ratio
by increasing the horizontal pixels employed.
The new dVision Scope 1080p projector inherits
the field-proven reliability and exceptional optical
qualities of DPI’s long-respected dVision series.
Suitable for home entertainment venues with medium
to large screens, the Scope 1080p is quiet, elegantly
designed and offers a diversity of system capabilities.
Installation flexibility is assured through an extensive
array of ultra-accurate optics, which provide
throw ratios as short as 0.8:1 and as long as 4.5:1.
Projector lumens and black level can be further optimized
to suit venue conditions through the straightforward
adjustment of the motorized lens iris. Additionally,
the Scope 1080p’s quick-change motorized
lens mount provides a broad range of horizontal
and vertical lens shift, allowing the projectors to be
placed in a wide variety of locations in relation to the
screen. Intuitive user controls and comprehensive
source compatibility ensure all dVision displays are
simple to integrate, control and operate.
