How to Build a Pixel-Perfect 1 Row x 2 Column Video Wall with MXNet 10G SDVoE

How to Build a Pixel-Perfect 1 Row x 2 Column Video Wall with MXNet 10G SDVoE

Introduction

A Pixel-Perfect video wall is display technology utilized by MXNet where multiple screens are arranged in a tiled pattern to create a single large display surface, typically within a Multiview. Each screen in the video wall is calibrated and adjusted so that the pixels on all screens match each other perfectly, creating a seamless and uniform display.

With AVPro's MXNet 10G SDVoE system, a pixel-perfect video wall can be constructed in the Mentor web UI where each pixel of every individual screen is aligned precisely with the pixels of the adjacent screens, and they all have the same brightness and color, creating a seamless image without any visual distortions or gaps.

Pixel-perfect video walls are commonly used in commercial settings, such as digital signage, control rooms, broadcast studios, and entertainment venues. They can display high-quality images, videos, and interactive content, making them ideal for creating immersive and engaging visual experiences for large audiences.

For more information on how to create a Multiview in general using the MXNet 10G SDVoE system, see this KB article.

Video Wall Modes

The MXNet 10G SDVoE system is capable of displaying a Multiview video wall in 2 different modes, selectable from the Video Wall Multi-View page within Mentor.

      Genlock Wall Mode

  1. All video wall decoders are synchronized (time-locked) to the source and also each other.
  2. Does not do Fast Switch or Frame Rate Conversion
  3. Better video quality than Fast Switch mode.

      Fast Switch Wall Mode

  1. Source changes on the video wall instantaneously
  2. One frame delay
