visual threshold

When will people stop being silly and understand that displays are optimal for general use once the dot pitch is below your visual threshold.

Visual thresholds near a continuously visible or briefly presented light-dark boundary.

Night vision systems enabled the measurement of visual thresholds following World War II.

This has been shown to result in loss of visual sensitivity but is unlikely to impair common visual tasks, except under conditions of reduced visibility when objects are already near visual threshold.

But beyond the global visual threshold, I well believe that it is the spectator's hand which is, through these paintings, grabbed, the unconscious hand seized by the delicate touch of these great digital surfaces.
