Much of the discussion of refresh rate does not apply to LCD monitors. This is because while a phosphor on a CRT will begin to dim as soon as the electron beam passes it, LCD cells open to pass a continuous stream of light, and do not dim until instructed to produce a darker color. Pertaining to LCDs, see also response time and Input lag.
On smaller CRT monitors (14") few people notice any change above 60–72 Hz. On larger CRT monitors (17", 19") most people would experience mild discomfort unless the refresh is set to a more comfortable 85 Hz or higher. 100 Hz is comfortable for most people. However, LCD monitors do not suffer from the same problems as their CRT predecessors and the refresh rate simply does not mean the same. LCD or TFT monitors will provide excellent quality and resolution at 60–Hz
