Image quality and ergonomics are two important factors to consider when choosing an LED Screen or video wall. When it comes to image quality, you must determine the right level of brightness, contrast and color consistency throughout the use of the system. Brightness and color are of crucial importance in various settings and are also important in comparing different types of displays. Although each video wall provides a lot of brightness especially when used in control rooms, the main challenge usually lies in proper maintenance of brightness throughout the video wall use. In this case, you must determine whether brightness and color are consistent throughout the video wall.
Secondly, determine whether manual intervention will be needed to keep the video wall balance in relation to brightness and color. In simple terms, you must choose an LED Display or video wall that will present the best color gamut. In addition, brightness displays on the video wall should make the system an attractive option for your specific environment. When it comes to ergonomics, you must determine the best viewing distance for all operations. Video walls installed in control rooms must be ergonomically affable for all supervisors and operators. It is actually a known fact that a video wall should be well designed for legibility of the operator.
Legibility is generally an aspect of the correct combination of a preferred pixel pitch and the collective resolution required to accurately display multiple applications across a video wall. Therefore, you must consider the viewing angle of the screen that will enable operators to properly maintain uniform view of the Video Wall with very limited brightness. Proper selection of the screen and operator positioning in front of a video wall is essential because it ensures that maximum positive results are achieved. Generally, a video wall with poor image quality and poor ergonomics is not worth having in your organization.
