Refresh rate

How often you need to refresh, to avoid flicker, depends on

Incandescent lights used to flicker with 25 Hz AC power, but not with modern 50 or 60 Hz.

These days it's recommended that computer monitors should be refreshed at 70 Hz or more.
With a million pixels on the screen, that requires very fast electronics!
