Nyquist frequency of human eye.

SUMMARY

The Nyquist frequency for the human eye is not a fixed value, as it varies based on content and individual perception. The concept of Flicker Fusion Frequency is more applicable, indicating the refresh rate at which the eye perceives continuous motion without flicker. High-quality televisions operate at refresh rates up to 240Hz, but typical video content ranges from 14 to 60 frames per second (FPS). Therefore, monitor design must consider both refresh rates and content type to minimize perceived flicker.

PREREQUISITES
  • Understanding of Flicker Fusion Frequency
  • Knowledge of monitor refresh rates
  • Familiarity with video frame rates (FPS)
  • Basic principles of human visual perception
NEXT STEPS
  • Research the impact of refresh rates on visual perception
  • Explore the principles of Flicker Fusion Frequency in detail
  • Investigate monitor technologies that minimize flicker
  • Learn about content-specific refresh rate requirements for optimal viewing
USEFUL FOR

Monitor designers, display engineers, and anyone involved in optimizing visual display technologies for enhanced user experience.

I'm designing a monitor and I've been getting various answers to this, seems to really depend. I've gotten everything from 10-120Hz.

There's is not really a Nyquist for the eye, the eye is "analog" - for monitors, and televisions you are looking for the refresh rate that the eye will not perceive the flicker - or strobbing of a digital image. The eye can pick up individual images at pretty high speed. That will depend on what will be on the monitor - High quality TV are at 240fps - but then it will still depend on the content and does it introduce distortion. Keep in mind that most video content is between 14 and 60 FPS

A better name for this is Flicker Fusion Frequency...
