The number of times the information displayed by the monitor is updated per second is called the refresh frequency.
The screen refresh rate is for a CRT monitor. Because a CRT monitor is a monitor that uses a cathode ray tube. The graphic images on the screen are made up of individual pixels that emit light due to the impact of electron beams. It is composed of phosphor dots. Since the phosphor in the picture tube emits light for a short time after being hit by the electron beam, the electron beam must continuously hit the phosphor to make it continue to emit light. For LCD, there is no refresh rate problem, because each pixel in the LCD is continuously emitting light until the voltage that does not emit light changes and is sent to the controller, so the LCD does not have "constant charging and discharging". caused by flickering.
How to change the refresh frequency:
1. Click Start, click Control Panel, click Appearance and Themes, and then click Display. Alternatively, you can right-click on the desktop and click Properties.
2. Click the Settings tab and then click Advanced.
3. Click the Monitor tab, and then click the screen refresh rate you want to use.
4. Click "Run" in the start menu, enter "dxdiag" in the interface that opens, select "Other Settings" in the interface that opens, see "Replacement", in the pop-up interface, select " "Replacement value", enter any value from [70-85], confirm. This is a forced modification of the monitor's refresh frequency. The refresh frequency is too low, such as the default 60HZ for general computers, which is quite irritating to the human eye, so it is better to increase it slightly.
Note: · The default refresh rate setting is 60 Hertz (HZ); however, the monitor may support a higher setting. For information about settings supported by your monitor, check the manufacturer's documentation.
· If you use a higher refresh rate, you can reduce the frequency of the screen flickering; however, if the specified refresh rate is too high for your monitor, the screen may become unusable and may Damage hardware.
