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. [10]As the flicker is most clearly seen at the edge of our vision there is no obvious risk in using a CRT, but prolonged use can cause a sort of retinal shock where the flickering is seen even when looking away from the monitor.
However, this does not apply to LCD monitors. The closest equivalent to a refresh rate on an LCD monitor is its frame rate, which is often locked at 60 fps. But this is rarely a problem, because the only part of an LCD monitor that could produce CRT-like flicker—its backlight—typically operates at around a minimum of 200 Hz.
Flicker: Perceptible on lower refresh rates (60 fps and below) [22] Depends; in 2013 most LCDs used PWM to dim the backlight [23] However, since then many flicker free LCD computer monitors were introduced. [24] Does not normally occur due to a high refresh rate higher than FPS [25] Does not normally occur at 100% brightness level.
This is distinct from, though can be combined with, spatial dithering, which uses nearby pixels at the same time. FRC cycles between different color shades within each new frame to simulate an intermediate shade. This can create a potentially noticeable 30 Hz (half frame rate) flicker.
Flicker-free is a term given to video displays, primarily cathode ray tubes, operating at a high refresh rate to reduce or eliminate the perception of screen flicker.For televisions, this involves operating at a 100 Hz or 120 Hz hertz field rate to eliminate flicker, compared to standard televisions that operate at 50 Hz (PAL, SÉCAM systems) or 60 Hz (), most simply done by displaying each ...

Jitter can cause a display monitor to flicker, affect the performance of processors in personal computers, introduce clicks or other undesired effects in audio signals, and cause loss of transmitted data between network devices. The amount of tolerable jitter depends on the affected application.
