You should also estimate the physical and pixel dimensions for the videowall. Once you are confident that your sample window layouts meet end user expectations, you can be sure that you have a good idea of the overall shape for the videowall, determined by the layout of the room and the source content to be presented. This topic is covered in detail in Font Size and Legibility for Videowall Content. In this case, upscaling may be necessary, possibly leading to use of larger window sizes that may require enlarging the videowall. While videowall processors allow images or graphics to be reduced in size, text or symbols may not remain legible if downscaled, or even when shown at native resolution.

Content can often be displayed in small windows as “thumbnails” to save space while being adequately discernible, and then upscaled or enlarged upon user control for closer examination. High resolution imagery may be reasonably legible when downscaled. The nature of the source content will be a determinant of how legible it may be when scaled. Having an idea of scaling requirements for the source content will help you determine relative sizes for the source windows on the videowall. When creating sample window layouts, it is also important to consider which sources should be shown at native resolution, those which may be downscaled or reduced in size, and content that should be upscaled or enlarged. Videowall images may be distorted if content is not presented in their native aspect ratios.
While many videowall processors will allow images to be stretched, zoomed, or cropped to fill a window of any shape, the end user may find it distracting if content is not represented in their native aspect ratios. Be sure to maintain each source’s original aspect ratio when designing these layouts. It will also be beneficial to sketch three or four storyboards with various window layouts. Discussing this with the end user, and deciding how source windows should be arranged on the videowall, will help determine the best overall screen arrangement. The size and aspect ratio of the source content and their intended arrangements on the videowall will also influence its shape and design.Ī good first step is to determine the types and resolutions of input sources to the videowall, and how many of them must be displayed together. But room layout is not the only important factor when determining the height and width of a videowall. Other room characteristics may result in a videowall shape closer to a square.
A shallow, wide room with a low ceiling will likely necessitate a short, wide videowall. What is the “best” shape or aspect ratio for a videowall? If the objective is to make the videowall as large as possible, then its shape will be driven by the layout of the room. Videowalls may also have creative shapes with no defined aspect ratio. However, each of these arrangements results in a different overall aspect ratio, which is defined by the layout of the screens as well as the aspect ratio of the individual display devices, which could be 4:3, 5:4, 16:9, or 16:10. Videowalls two screens high by four screens wide, three screens high by four screens wide, or four screens high by four screens wide are common. When specifying a videowall system, a design engineer has the flexibility to define a specific layout for the displays. A videowall in a public setting for digital signage will have far different physical requirements than a videowall in a command and control center.ĭeciding how large a videowall should be is more than a matter of determining how many display devices are required to fill a space on a wall. The manner in which the videowall will be used, the types and quantity of information to be presented, and the size and shape of the room should be considered before selecting the quantity and type of display. Choosing the Right Videowall Shape and Sizeĭeciding how large a videowall should be is more than a matter of determining how many display devices are required to fill a space on a wall.
