What does the refresh rate of the desktop mean and what is the screen refresh rate?

Each time you refresh the system, you will check for changes to the file. In other words, the system will spend a certain amount of resources on inspection. If it is refreshed on the desktop at boot, the speed must be slow, because the background service is starting, in other words, the system is busy.

If you wait for the background service to start,That is to say, the chart of the desktop will be opened immediately,At this time, the refresh is a little slow for the first time,The last few times it will be normal。 Also, viruses and Trojan horses are generally not visible by refreshing. If you want to refresh quickly, there are two ways, one is to upgrade the hardware, and the other is to turn off background services and system programs as much as possible.

You may have a process that has not been fully started when you just boot the computer.

It may be a little slow when refreshing, this is normal, and there is nothing wrong with this.

Wait until all the processes on your computer have started and then refresh it, and it's very fast.

Of course, you can get rid of some of the startup items that don't work, and if you don't know how to get rid of them, you can use 360

Refresh means:

If you're working on a file, it's a rearrangement of the file;

If it refers to the screen refresh, it refers to the refresh circuit of the display to rescan the screen;

Increasing the refresh rate can be done in two ways.

From a hardware perspective, the most important factor affecting the refresh rate is the bandwidth of the display, which is directly proportional;

From a software perspective, the biggest influence on the refresh rate is the resolution of the screen, which is inversely proportional.

The refresh rate refers to the number of times the electron beam reiterates the image on the screen, and the higher the refresh rate, the better the stability of the displayed image (picture). The refresh rate will directly determine it**, but since the refresh rate and resolution are mutually restricted, only a display that achieves a high refresh rate at high resolution can be called excellent.

The refresh rate is the number of times the screen is refreshed per second, and what you see when watching a movie is actually a still picture, just like putting a slideshow, because the human eye has a visual retention effect, and the impression of the previous picture in the brain has not disappeared, and then the next picture will follow, and the difference between the two pictures is very small.

An action has to be displayed with many pictures, so that it feels like the picture is moving, this pair of replacement screens, is refreshing, assuming that an action is completed by 20 pictures, it looks a bit like a cartoon, and this action is increased to 30 photos, it looks much more natural, this is the refresh rate.

Basic type:

An integral part of the developing tube shell. The inner layer is coated with phosphor, and when the electrons hit the screen, it emits light spots, which can display waveforms or images, and BSV LCD splicing technology uses LED backlight to achieve uniform color display.

A television or radar receiver or similar instrument displays a panel of images or patterns, the inner layer of the screen is coated with phosphor, and when an electron hits the screen, it emits a point of light, which can display a waveform or image.

Refers to the number of times an electron beam repeatedly scans an image on a screen.

The refresh rate is the number of times the screen is refreshed per second, when we watch a movie, what we see is actually a static picture, just like a slideshow, why do we feel that the picture is moving, it is because the human eye has a visual stay effect, the impression of the previous picture in the brain has not disappeared, and then the next picture will follow, and the difference between the two pictures is very small, an action has to be displayed with many pictures, so that we feel that the picture is moving, this one by one replacement picture, It's refreshing, assuming that an action is done by 20 screens, we look a bit like a cartoon, and if this action laugh cover is increased to 30 pictures, it looks much more natural, this is the refresh rate.

Its unit of calculation and vertical scan frequency are both Hz, but these are two very different concepts. The 75Hz picture refresh rate is the most basic standard for VESA to be flicker-free, and 75Hz here should be the standard that can be met by all display modes.

Analysis: The so-called "refresh rate" refers to the number of times the screen is refreshed per second, also known as the field frequency or vertical scanning frequency. The image on the CRT monitor is made up of many fluorescent dots, each of which emits light due to the impact of an electron beam, but the luminescence dots emit light for a short time, so it is necessary to continuously hit the phosphor by an electron beam to make it shine continuously.

The electron gun inside the CRT scans from the leftmost to the rightmost end of the first row, then from the leftmost end of the second row to the rightmost end, followed by the third row, the fourth row, and ......Until it is scanned to the lower right corner, the entire screen has been scanned and traced, that is, a refresh has been completed. Theoretically speaking, as long as the refresh rate reaches 85Hz, that is, 85 refreshes per second, the human eye will not feel the flickering of the screen, but in actual use, some people can often see the difference between the 85Hz refresh rate and the 100Hz refresh rate uplift, so from the perspective of eye protection, the higher the refresh rate, the better.

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, measured in Hz (hertz). When we refer to the refresh rate in general, we usually mean the vertical refresh rate. Generally speaking, if the refresh rate is above 85Hz, the human eye will not feel the flicker, which is very good for ensuring eye health.

The refresh rate of a computer screen refers to the number of times an electron beam repeatedly scans an image on the screen, generally speaking, the higher the refresh rate, the more stable and clear the image will be.

Specifically: 1. If it is a CRT monitor, it can generally be set to 85Hz.

2. If it is an LCD monitor, it can generally be set to 60-75hz.

3. Some LCD displays with new frequency doubling technology can be set to 120-144Hz.

Now the mainstream display material is IPS screen. Refresh rate is also an important concept, the number of times the screen refreshes an image in one second. The higher the refresh rate, the more images are refreshed per second, and the more stable and clear the image will be.

Conversely, if the refresh rate is low, the image is prone to flickering and jitter. Theoretically, the more images are refreshed per second, the smoother it will be. For example, 60Hz is 60 refreshes per second, while 144Hz refreshes 144 times per second.

There are a few things to consider when choosing a refresh rate:

1. Whether your computer hardware can support a higher refresh rate. If your PC is poor, a high refresh rate may cause problems such as game stuttering and screen tearing.

2. Does your monitor support a higher refresh rate? Different monitors have different maximum refresh rates, and too high a refresh rate may damage the display.

3. Your use needs. For ordinary office use, a 60Hz monitor is sufficient. For players, a high refresh rate can lead to a smoother gaming experience. However, displays with high refresh rates are more difficult to refresh and are not needed by everyone.

It's important to note that a high refresh rate isn't available for all games. In non-shooter games, a high refresh rate may not result in a noticeable boost. And in shooting games, a high refresh rate can lead to smoother graphics and more accurate operations.

Therefore, when choosing a refresh rate, you need to consider it in combination with your own usage needs.

Summary. The screen refresh rate refers to how many times per second the screen is redrawn, starting from the top left corner of the screen. Generally speaking, the higher the screen refresh rate, the smoother the picture of the display.

The screen refresh rate refers to how many times per second the screen is redrawn, starting from the top left corner of the screen. Generally speaking, the higher the screen refresh rate, the smoother the drawing of the display screen.

1.Pay attention to personal protection: During the epidemic, you should pay attention to personal protection, wear a mask when you go out, don't go to crowded places, and avoid gatherings.

At home, you should often open the windows for ventilation, and try not to go to medium and high-risk places. 2.Regular rapid nucleic acid testing:

Usually pay attention to regular nucleic acid slippery testing in order to understand your physical health. If the nucleic acid is positive, timely isolation** will help cut off the route of transmission in time. 3.

Vaccination: If individuals do not have contraindications to vaccination, it is recommended to get vaccinated as soon as possible to strengthen their resistance to the disease. We should take precautions, pay attention to personal hygiene, and wash our hands frequently.

If you have to go out under special circumstances, wear a disposable medical mask and try not to go to crowded and crowded places.
