Let’s find out what video walls are. They are classified according to:

from the elements that make up the screen:

  • LCD displays or LCD panels. A professional LCD video wall can be used to display information in high definition.
  • LED screens (based on LEDs). Models with LED screens are ideal for outdoor advertising. They are bright enough.
  • rear projection video cubes (including those with laser illumination). Solutions based on video cubes are less sensitive to the illumination of the installation site.
  • split screens of projector images stitched together. Usually these video walls are not too bright. However, they need more space for installation.

on screen size:

  • small (from 4 to 8 panels) – for control rooms and conference rooms of small sizes.
  • medium (from 9 to 16 panels) – for control rooms, situational and monitoring centers, at concerts and TV studios.
  • large (from 17 panels) – for large monitoring centers.

by type of installation:

  • mobile – video walls that can be rolled on a special rack with a chassis.
  • stationary – video walls mounted on a wall, on a rack or on the floor, but not designed to be moved. When installing such a solution, you will have to decide in advance where the video wall controller and other switching will be located.

Video walls are also classified depending on the thickness of the interpanel seam . The picture will look more coherent if the panels are with a narrow frame or almost without it. The top solutions have a seam of 0.5 -1.5 mm (seamless). However, they are less affordable.

Video walls differ in brightness. Solutions with low brightness are suitable for indoors, but with maximum brightness – for the street. The brightest are considered to be on LED screens, as well as projection cubes with laser illumination.

In addition, video walls may differ in the arrangement of elements. Panels can be placed not only horizontally. They can be placed vertically, as well as obliquely, etc. Panels for video walls can be organized into a three-dimensional structure – a panorama. Switching such an unusual system will be a difficult task, since it will be necessary to use a non-standard or exclusive scheme.

Now all the listed types of solutions are presented on the CIS electronics market. For example, you can easily buy a video wall in Moscow in our store. We have solutions for every taste.

Video wall equipment selection criteria

A video wall usually consists of three basic elements: panels (displays), mounts (brackets or mobile stands) and a controller. Let’s find out how to choose the right equipment for her.
First of all, pay attention to the task that you want to solve by installing a video wall:

  • broadcasting of mass events (sports competitions, show programs) on large venues;
  • making presentations in conference rooms;
  • demonstration of multimedia information in shopping centers;
  • creation of an information screen for dispatch services and situational centers.

For example, if the solution is to be used at public events, it must have a sufficiently large screen size. After you decide on the task, proceed to the choice of panels.

Depending on the type of matrix, panels can be of the following types:

  • LED screens are displays based on LED elements. They are used in outdoor advertising. Solutions based on them have high image brightness and reliability. There are also LED-panels with laser illumination, which are less dependent on the illumination of the place. Their brightness is almost 2 times more than others.
  • LCD displays are displays made from liquid crystals. So-called LCD screens. Based on them, you can build a high-resolution video wall. Such a solution can provide a detailed image. This is essential, for example, in the field of professional dispatcher monitoring.

Panels for video walls differ in the width of the frames. Not so long ago, they also appeared with an ultra-thin frame (up to 1 mm). With their help, it became possible to build seamless video walls. They are now widely used in airports, hotels, medical centers – everywhere where there is a need for round-the-clock information display. Buying a seamless solution will cost more. But given that the thickness of the seam is one of the determining parameters in the usability of a video wall, it will be useful to overpay.

Now that the panels are selected, you can look at the rest of the equipment:

  • device that will act as a video signal source. Usually this is the PC from which the signal is transmitted further.
  • video wall controller. Such a device receives a signal from the source and directs it to the screen. It is it that provides the output of the image in multi-window mode. The controllers differ in purpose (depending on the type of processed video signal), design and number of outputs. You can learn more about how to choose a controller from our blog article.
  • mounts and/or racks. Depending on whether or not you will move the video wall in the room, it can be wall brackets or mobile stands. Without them it is impossible to carry out its correct installation.
