High resolution makes the picture as clear and comfortable for viewing as possible. Expressiveness of colors provides realism of the depicted objects. Clarity allows you to view the picture on the screen in detail, being at a considerable distance. And the ability to receive and broadcast a video stream from multiple sources simultaneously, helps to get important information in real time.<\/p>\n<p>Seamless video walls are successfully used to display video and static images in the following devices and spaces:<\/p>\n<ul>\n<li>Trainers to create the most realistic environment possible.<\/li>\n<li>Conference rooms to show graphs, charts and tables to illustrate a report.<\/li>\n<li>Tele and radio companies, where it is important to promptly receive and air current news.<\/li>\n<li>.<\/li>\n<li>Situation centers for analysis of current events.<\/li>\n<li>Dispatch centers for displaying maps or video.<\/li>\n<li>Trade and entertainment centers for displaying advertisements, broadcasting festive events.<\/li>\n<li>Lecture halls, etc.<\/li>\n<\/ul>\n<h2>Purpose of the technique<\/h2>\n<p>Parameters of seamless video walls, reaching dozens of meters in height and width, allow to use the systems for demonstration of any types of content, broadcasting from different channels, instant display of digital and scanned images. For the correct display of information, a controller is used. Its task is to scale and change the location of pictures, switching between channels, signal distribution from multiple sources, providing live streaming with minimal risk of interruptions and freezes. Thanks to the controller, the management of the video wall becomes easier, and the probability of malfunctions in its operation can be reduced to zero.<\/p>\n<h2>Video Wall Types and Differences<\/h2>\n<p>The following classification allows you to navigate in the variety of multimedia designs and unmistakably choose a model for specific tasks. By purpose distinguish devices for classrooms of educational institutions, for reception, for fitness rooms, for meeting rooms, for dispatch centers, mobile devices for installation indoors or outdoors. By the number of displays &#8211; 2*2, 3*3, 4*4, models for individual projects with a different configuration of horizontal or vertical arrangement of TVs. The size of the seam between the elements can be 0.88, 1.8 or 3.5 mm.<\/p>\n<h2>Design of the video wall<\/h2>\n<p>A video wall consists of:<\/p>\n<ul>\n<li>A number of displays depending on the chosen configuration.<\/li>\n<li>Necessary number of mounts, brackets and cables HDMI, Display Port, VGA.<\/li>\n<li>Switchboard. This is a device for receiving signals from several channels with a control panel, which is connected to the system using cables such as HDMI, DOP, VGA, selected depending on the inputs of the transmitter.<\/li>\n<li>Video processor (video controller). This device is necessary for simultaneous work with different channels without loss of image and video quality. It can be used to display video of several users at once, transfer control rights or monitor the system remotely.<\/li>\n<\/ul>\n<h2>Panel type<\/h2>\n<p>There are two main types of panels: LCD (LCD) and LED. The first are so-called professional LCDs, which are suitable for small walls or large configurations in rooms with a large or limited area. Such a solution can be called ideal for showing high-resolution pictures or detailed images that require detailed study.<\/p>\n<p>LED video wall &#8211; LED video panels. Their main advantages are brightness of color and increased resolution. However, such models have significant application limitations. At a short distance, the viewer may feel uncomfortable because of the many pixels &#8211; dots that make up the image. And monitors with a fine grain pitch have a higher price, available to a limited contingent of buyers.<\/p>\n<h2>Use outdoors or indoors<\/h2>\n<p>.<br \/>\nModern panels are suitable for use in the open, including &#8211; in special climatic conditions. The only requirement &#8211; the presence in the instructions for use of an indication of the permissibility of installation on the street. The optimal solution in this case will be LED panels, which are adapted for the design of multimedia facades of buildings.<\/div><\/div>[\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][\/vc_column][\/vc_row]<\/p>\n","protected":false},"author":1,"featured_media":6107,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[187],"tags":[],"class_list":["post-5816","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-bez-kategoriyi-uk"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/livesound.in.ua\/en\/wp-json\/wp\/v2\/posts\/5816"}],"collection":[{"href":"https:\/\/livesound.in.ua\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/livesound.in.ua\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/livesound.in.ua\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/livesound.in.ua\/en\/wp-json\/wp\/v2\/comments?post=5816"}],"version-history":[{"count":0,"href":"https:\/\/livesound.in.ua\/en\/wp-json\/wp\/v2\/posts\/5816\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/livesound.in.ua\/en\/wp-json\/wp\/v2\/media\/6107"}],"wp:attachment":[{"href":"https:\/\/livesound.in.ua\/en\/wp-json\/wp\/v2\/media?parent=5816"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/livesound.in.ua\/en\/wp-json\/wp\/v2\/categories?post=5816"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/livesound.in.ua\/en\/wp-json\/wp\/v2\/tags?post=5816"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
