In general, video walls are formed of interconnected specialized monitors. They differ from conventional monitors in the width of their frames and the fact that they can be calibrated, which helps to ensure uniform colour gamut, brightness, etc. of the monitors. Novelty on the market: self-calibrating monitors.
When selecting a video wall, it is very important to choose the right monitor size, which affects the overall size of the video wall when it needs to fit specific dimensions. The diagonal of a screen ranges 43 to 55 inches and can take any format chosen by the customer, starting with 1×2, 2×2 and so on.
Based on the customer’s request, the monitors can be mounted both vertically and horizontally, which enables the creation of exceptional shapes of video walls. However, if a solution of a highly non-standard format is required, each of the monitors may also need dedicated content players to facilitate the further processing of the image in order to adapt it to the selected video wall format. It should be noted that several different video sources may be displayed on a video wall.
The maximum operating capacity of such monitors ranges 16 to 24 hours per day, and the brightness, depending on the lighting in the premises where they are used and the intended purpose of use, can equal 350 to 700 nits.
The width of each monitor frame also plays a significant role when it comes to video walls. The distance resulting from the sum of the width of two frames is also known as ‘bezel to bezel’.
The smaller the gap, the less it interferes with the accurate transmission of the content. By now, the smallest available ‘bezel to bezel’ gap is 0.88mm, the average reaches 1.8mm (most commonly chosen by customers), and the largest is 3.6mm.
Such monitors also have a frame compensation function, which is required to maintain an integral image even where the frame covers the content.
The video wall can be mounted both by inserting it into a niche and simply on a wall, in both cases using pop-out mount, which, when clicked on, automatically push out the monitors for servicing. A video wall can also be mounted on a mobile or stationary stand.
