How Far?  What Resolution?  What Density of Pixel?

James Fife | 19 February, 2018

Visual Acuity-1.pngI am often asked about the relation of video technology and viewer position and typically in two forms.  First, “how far away can a viewer be before they see a good image on a screen/tile/display?”  Or the opposite, “I have a room that is this 17' (5.2m), so what resolution or image density should I use in the design?”   Well, the answer is possible to calculate, but first you have to understand what a pixel is, what parts make it up, and the math that allows all the parts to be calculated.  I am going to start a mini-series leading up to an article release in February tying this into how to calculate viewing distance using a technology agnostic formula set based on human vision.  So stay tuned!  This series is going to change the way you think of video in a today’s modern environment.
