Show+Tell Launches Design App for Large-Format Video Displays

Large-format LED video wall displays are becoming widely used to create dynamic spaces. Show+Tell's Retina Calc helps retail, architectural, and environmental designers better understand the relationship between viewing distance, pixel pitch, and perceived image quality.

The term “Retina Display” was coined by Apple to describe a screen with a resolution high enough that the average eye cannot see the individual dots which make up the image. The calculation is a combination of pixel pitch (the closeness of the pixels which make the image) and distance of the viewer from the display.

Specifically, this calculator from Show+Tell (New York) will help you determine the best viewing distance for a given pixel pitch or, conversely, the best pixel pitch for a given viewing distance.
