Liquid crystal display refresh rate how much appropriate

Accurate LCD and LED LCD screen refresh rate and the display panel has only a relationship, and the ordinary computer LCD display is the LCD panel and backlight source of the structure, LCD and led only two different light source and refresh rate is completely not related. The LCD display defaults to 60 hertz.

Refresh rate is divided into vertical refresh rate and horizontal refresh rate, generally referred to the refresh rate usually refers to the vertical refresh rate. The vertical refresh rate indicates how many times the image of the screen is redrawn per second, that is, the number of screen refreshes per second, in Hz (Hertz). The higher the refresh rate, the more stable the image, the more natural and clear the picture display, the smaller the impact on the eyes. The lower the refresh rate, the more the image flashes and shakes, and the faster the eye is tired. In general, if you can achieve more than 80Hz refresh rate can completely eliminate the image flicker and jitter, the eyes will not be too easy to fatigue.

Obviously the higher the refresh rate is better, but it is recommended that you do not let the display has been working at the highest refresh rate, which will accelerate the CRT tube aging, generally lower than the highest refresh rate of one to two stalls is more appropriate, recommended 85Hz. The light-emitting principle of the liquid crystal display (lcd/led) is not the same as the traditional CRT, because each point of the liquid crystal display keeps the color and brightness after receiving the signal, and it doesn't need to be refreshed as much as the cathode ray tube display (CRT). Therefore, the high quality of the liquid crystal display and will never blink, the eye fatigue to the lowest. and refresh rate on the significance of the CRT is more prominent, sometimes, lcd/led refresh, but will affect its service life as long as 60-75 can be.

Here is a brief introduction to the Win 7 system how to adjust the refresh rate, of course, this refresh rate and the game inside the refresh rate, and the movie inside the frame/second is not a concept ... will not affect each other.
