The flicker of a CRT monitor can cause various symptoms in those sensitive to it such as eye strain, headaches [9] in migraine sufferers, and seizures in epileptics.

A cathode-ray tube (CRT) television displays an image by scanning a beam of electrons across the screen in a pattern of horizontal lines known as a raster. At the end of each line, the beam returns to the start of the ...
Screen-door effects are more noticeable than LCD when up close, or on larger sizes. [53] New models are no longer produced. Colored sub-pixels may age at different rates, leading to a color shift, although some models will scan pixels to even out wear and prevent this shift. [54] Sensitive to UV light from direct sunlight.
Display motion blur, also called HDTV blur and LCD motion blur, refers to several visual artifacts (anomalies or unintended effects affecting still or moving images) that are frequently found on modern consumer high-definition television sets and flat-panel displays for computers.
This ability (plus built-in genlocking) resulted in the Amiga dominating the video production field until the mid-1990s, but the interlaced display mode caused flicker problems for more traditional PC applications where single-pixel detail is required, with "flicker-fixer" scan-doubler peripherals plus high-frequency RGB monitors (or Commodore ...

This can create a potentially noticeable 30 Hz (half frame rate) flicker. Temporal dithering tends to be most noticeable in darker tones, while spatial dithering appears to make the individual pixels of the LCD visible. [1] TFT panels available in 2020 often use FRC to display 30-bit deep color or HDR10 with 24-bit color panels.
