Simple video walls can be driven from multi-monitor video cards, however more complex arrangements may require specialized video processors, specifically designed to manage and drive large video walls. For example, the 100-inch video wall located in the main lobby of the Lafayette Library and Learning Center has enough size for the distant passerby to view photos while also providing the nearby observer enough resolution to read about upcoming events.
Video walls can also benefit smaller venues when patrons may view the screens both up close and at a distance, respectively necessitating both high pixel density and large size. Examples include the video wall in Oakland International Airport's baggage claim, where patrons are expected to observe the display at long distances, and the 100 screen video wall at McCarran International Airport, which serves as an advertising platform for the 40 million passengers passing through airport annually. Video walls are sometimes found in control rooms, stadiums, and other large public venues. Reasons for using a video wall instead of a single large screen can include the ability to customize tile layouts, greater screen area per unit cost, and greater pixel density per unit cost, due to the economics of manufacturing single screens which are unusual in shape, size, or resolution. A command signal may, for example, power all screens in the video wall on or off, or calibrate the brightness of a single screen after bulb replacement (in Projection-based screens). Such screens often contain the hardware necessary to stack similar screens together, along with connections to daisy chain power, video, and command signals between screens. Screens specifically designed for use in video walls usually have narrow bezels in order to minimize the gap between active display areas, and are built with long-term serviceability in mind. Later Diamond vision displays and all Jumbotrons used field-replaceable modules containing several flood gun CRTs each, one per subpixel, that had common connections shared across all CRTs in a module the module was connected through a single weather-sealed connector. Early Diamond vision displays used separate flood gun CRTs, one per subpixel. Diamond Vision was historically similar to Jumbotron in that they both used cathode-ray tube (CRT) technology, but with slight differences between the two. Jumbotron technology was also previously used. Typical display technologies include LCD panels, Direct View LED arrays, blended projection screens, Laser Phosphor Displays, and rear projection cubes.
Do you provide customer support? Yes, we have full customer technical support for any bugs, and we can customize the software to your needs too.A video wall is a special multi-monitor setup that consists of multiple computer monitors, video projectors, or television sets tiled together contiguously or overlapped in order to form one large screen.
Software takes only a few seconds to install and be running. Is it easy to install? Yes, it was designed to be easy and fast to install.
Screencasting from iPhone and Android are planned for the future. How does screencast work? You can screencast from Microsoft Windows, Linux or Mac using a regular browser.
You can use a tablet or phone to send shoot commands (so the PC can be just a server hidden from view), but the PC is necessary to control everything and process data. Do I need a PC to control the system? Yes, you need a PC running Microsoft Windows or Linux.
You can use fewer screens than your license allows too, but not more.
How does licensing work? You get a license for a number of screens. Are there plans for resellers and distributors? Yes. Where is the REST API documentation? Read the REST API documentation here. Buy online right now! How does your video wall controller works? There is a small server software that handles content and user interface, communicating to client software that runs on Linux, Windows, Android or Raspberry Pis. What can Corollarium Videowall be used for? Digital signage, large screen installations, operation centers, advertisement, control rooms and more.
