As far as I know, most monitors have a refresh rate of 60Hz.
Old fashioned CRT monitors drew the picture on the screen by hitting phosphor with an electron ray. The beam moved on and the phosphor would continue to glow for a short while. You needed to refresh this again with in a short period. 50 times per second was enough to produce a usable image. (In televisions they used longer glowing phosphors and refresh it 25 times per second, interlaced).
- A faster refresh yielded a slightly less tiring image.
- Having the refresh rate of the CRT at the same frequency of the fluorescent tubes used in many offices resulted in interference.
For these reasons the refresh was often increased to 60, 72, or 75 times per second.
(Often limited by the capabilities of both the monitor and the graphical card).
This means the refresh rate of 60Hz is not quite universal, and only found in older CRTs or in offices where cheap CRTs or cheap graphical cards got used.
'LCD' screens however work differently. *1
With a flat panel the image is not refreshed as such. The display keeps the last image until changed. This yields a crispy, stable image.
Changing this image however takes some time. The first generation flat panels which got sold as monitors had a delay of about 50ms to change a pixel from black to white or vice versa. This is fine for office work, surfing etc etc.
Given its more stable image I think it is even better for most tasks, despite being slower.
Its only disadvantage would be with rapidly changing images (E.g. gaming). For those you either want a CRT or a monitor with a rapid screen refresh. 25ms or faster used to be accepted as enough for gaming.
I know, not LCD but TN, IPS etc etc. However LCD seems to be the commonly used term. That or 'flat panel'.
