What does 60hz mean?

60Hz on the monitor refers to the refresh frequency of 60HZ. The speed at which the image updates on the screen, that is, the number of times the image on the screen appears per second, is measured in Hertz (Hz). The higher the refresh frequency, the smaller the flicker of the image on the screen and the higher the stability. In other words, the better the protection of eyesight.

60Hz on the monitor refers to the refresh frequency of 60HZ.

The speed at which the image updates on the screen, that is, the number of times the image on the screen appears per second, is measured in Hertz (Hz).

The higher the refresh frequency, the smaller the flicker of the image on the screen and the higher the stability. In other words, the better the protection of eyesight. Normally, the human eye cannot easily detect the flicker caused by refresh rates above 75Hz, so it is best to adjust the refresh rate of your display card to above 75Hz.

It should be noted that not all display cards can achieve a refresh rate of more than 70Hz at the maximum resolution (this performance depends on the speed of the RAMDAC on the display card), and the display may also have insufficient bandwidth. and cannot meet the requirements.

Maintenance:

1. Avoid burning out the inside of the screen. CRT monitors can be burned out due to long-term work, and the same is true for LCDs, so be sure to pay attention. , if not in use, be sure to turn off the monitor or reduce the display brightness of the monitor, otherwise it will cause internal burnout or aging over time. Once this damage occurs, it is permanent and irreversible. In addition, if a fixed content is displayed continuously for a long time, it may cause some LCD pixels to overheat, causing internal burnout.

2. Pay attention to maintaining humidity. Generally, the monitor can work normally if the humidity is maintained between 30% and 80%. However, once the indoor humidity is higher than 80%, condensation will occur inside the monitor. The internal power transformer and other coils are prone to leakage after getting wet, and may even cause a short circuit; the high-voltage parts of the monitor are prone to discharge; the components inside the machine are prone to rust and corrosion, and in severe cases, the circuit The board has a short circuit. Therefore, LCD monitors must be protected from moisture. Monitors that are not used for a long time can be powered on regularly for a period of time, so that the heat generated by the monitor during operation can drive out the moisture inside the monitor.

Also, do not let anything with moisture properties enter the LCD. If you find any fog, gently wipe it off with a soft cloth before turning on the power. If moisture has entered the LCD, the LCD must be placed in a warmer place to allow the moisture and organic compounds to evaporate. Applying power to an LCD containing humidity can cause corrosion of the liquid crystal electrodes, causing permanent damage.

3. Clean the display surface correctly. If you find stains on the display surface, gently wipe them off with a soft cloth moistened with a little water. Do not spill water directly on the display surface. Water entering the LCD will cause the screen to short out.
