Viewing distance

  • Minimum viewing distance = 30.4inch = 2.53foot = 0.772meter
    (max 70° viewing angle for full field-of-view experience)
  • Visual Acuity minimum distance = 62.4inch = 5.2foot = 1.59meter
    (pixel < 1/60° so that individual pixels cannot be seen)
  • Ideal viewing distance = 67.4inch = 5.61foot = 1.71meter
    (30° viewing angle for full field-of-view experience)
  • Maximum viewing distance = 77.5inch = 6.46foot = 1.97meter
    (min 26° viewing angle for full field-of-view experience)
