The computer display or television screen operates on the principle of change of successive frames. This principle is similar to the work of a film projector. When watching a movie frame rate of approximately 25-30. Due to the complexity of the image on a computer or TV screen, its refresh rate should be much higher. This index will affect the image sharpness. Thus, the choice of TV or PC monitor is better to give preference to goods for which the rate is higher.
The first versions of the monitor shows the average quality of the picture. The user can notice the screen flicker when the image changes. Because of this, it was recommended to use protective shields, and in the course of continuous operation for such monitors should have done a few breaks to relieve the load on the eye.

REFERENCE! As a result of technological development to replace CRT monitors came more modern screens: LCD and TFT-monitors. Initially, they lagged significantly in brightness, contrast, and image quality was low. However, long-term process improvements will deliver higher quality indicators, which led to an increase in the popularity of such models.
What affects the refresh rate of the computer screen
If the display personnel rather low frequency, then, as described above, visual display flickers. While the highest rate of this parameter allows you to make shimmer virtually invisible, and it improves the image pickup comfort.
The average refresh rate of the screen is considered to be 60 Hz. This is quite enough for comfortable work. In advanced models of the liquid crystal monitor screen refresh rate reaches 144 Hz or even 240 Hz. This makes it possible to increase the smoothness of the image. Such displays are well suited for gaming.
