This work determines the maximum display resolution that the human eye can discriminate. The limit was determined for achromatic and chromatic vision, for both the fovea and periphery.
Our results demonstrate that the resolution limit is higher than what was previously believed, reaching 94 pixels per degree (ppd) for foveal achromatic vision, 89 ppd for red-green patterns, and 53 ppd for yellow-violet patterns. We also observe a much larger drop in the resolution limit for chromatic patterns (red-green and yellow-violet) than for achromatic patterns. Our results provide quantitative benchmarks for display development, with implications for future imaging, rendering, and video coding technologies.
