Factors that determine price/quality

  • Resolution
    • Number of pixels in the display

  • Field of View (FOV)
    • Angle (in degrees) of the visual field.
    • Varies from person to person, but typically 180 degrees (horizontal)
    • 60 to 90 degress is the usual minimum for a feeling of immersion

  • Display technique
    • Usually LCD, but sometimes CRT

  • Size/weight in combination with the factors above
