Edge Overlap with C-Series: Simplify multi-projector edge blending

Edge Overlap displays a single continuous image across multiple blending-enabled projectors

The Matrox PowerDesk Edge Overlap feature allows C-Series users to easily and intuitively adjust the number of overlapping pixels between edge blending projectors to create a seamless, unified image. With Edge Overlap natively supported at the GPU level and no scaling required, C-Series cards provide outstanding image quality for all standard applications—across the entire desktop—for a very effective collaborative work environment.

Matrox C-Series cards can be combined with affordable edge blending projectors to provide a unique, cost-effective solution for boardrooms, classrooms, digital signage applications, and worship and presentation environments looking to drive seamless digital content on up to six projectors in a wide range of configurations.

Use Simple and Cost Effective Equipment

The Matrox PowerDesk Edge Overlap feature for C-Series graphics cards creates affordable multi-projector solutions that avoid the higher costs and complexity associated with ultra-high-end projectors and custom projection hardware and software.

Use three basic system components to power up to six blended projectors—a Matrox C-Series graphics card, one standard computer, and up to six edge blending projectors. There is no need for additional and expensive software or hardware such as software-based blending applications or external hardware blending components, which complicates installation setup, adds costs, and increases support issues.

Using a Matrox C-Series card lets value-added resellers and system integrators benefit from using a single common off-the-shelf commercial system to build multi-screen, overlapped projection setups.

Project Seamless and Pristine Images

To show content across multiple projectors seamlessly, Matrox Edge Overlap duplicates the GPU’s output edges. This allows each output edge to be physically overlapped with the other. The fine details of manipulating the number of overlapped vertical and/or horizontal pixels is managed by the PowerDesk user interface with simple and easy-to-use controls. At the point where the image is lined up, the image naturally appears brighter where the projected images overlap.

Projector edge blending resolves the brightness effect by adjusting the light intensity for the overlapped parts of the image to match the rest of the projected content.

Combine Matrox Edge Overlap feature with edge blending technology to create a perfectly aligned, seamless, pristine image with even light intensity displayed across two to six projectors.

Flexible Multi-Projector Options

The Matrox Edge Overlap feature can be enabled in a variety of multi-projector set ups with C-Series cards, whether they are positioned in landscape or portrait mode and in either a horizontal and/or vertically-stacked configuration.

Example 1.
Three landscape projectors are positioned in a 3x1 horizontal configuration.
space Example 2.
C420 can connect up to four projectors in multiple configurations, including 4x1 (horizontal), 1x4 (vertical) and 2x2 (square) with projectors in landscape or portrait/pivot modes.

Example 3.
Use a C680 six-output card for large projection applications, including a 3x2 configuration.
 
 

Easy and Intuitive Setup

If you already have a Matrox C-Series graphics card installed, setting up the Matrox PowerDesk edge overlap feature is fast and easy to do.

  1. Access Matrox PowerDesk desktop management software from your desktop
  2. Choose "Edge overlap and bezel management" from the menu choices.
  3. Select "Edge Overlap" and adjust each projector's horizontal and/or vertical seams by choosing the overlap pixel density.

Works with Affordable Edge Blending Projectors

The Matrox PowerDesk Edge Overlap feature included in all C-Series cards supports edge blending projectors (examples: Mitsubishi 8000 Series and Panasonic D6000 series). These projectors provide excellent image quality, ever-increasing luminance, high reliability, and cost-effectiveness.
