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 lens solution.

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 front.”

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.
