Don't always degauss, it's not necessary, if you find that you are often magnetized, or look for anything with strong magnetism around, important is audio and video, if there is, keep them away.
If the display is magnetized, the display will be color cast, and this can only be solved by degaussing.
In fact, the display itself also produces a magnetic field in the process of use, but it is relatively weak, and generally does not magnetize the screen, so in order to ensure that the slight magnetization phenomenon can be eliminated, there is a degaussing coil behind the display, which is connected to the AC power supply after being connected in series with a degaussing resistor, and the instant degaussing resistance is relatively small, so the degaussing coil will produce a large magnetic field to degauss the display, this time is relatively short, as the degaussing resistance gradually increases, the degaussing magnetic field will weaken. Small magnetization problems can be solved by the degaussing function that comes with the display. The same is true of the principle of home televisions.
If you feel that you are often magnetized, you can check whether the degaussing resistor has been disconnected, this resistor should be easy to buy and not expensive.

Maybe there is a reason for aging.

Degaussing once is enough. Don't use it too much. If the color is not right, see if you can adjust it.,If you can't adjust it, it should be a problem with the display.。。 Aging..

Not good, it doesn't matter.
The old saying goes.
Or the color temperature is wrong, adjust it to 9300K

To put it simply, the display is magnetized by the surrounding magnetic field (speakers, transformer power supply, etc.) to be demagnetized when it appears at the plate point, look down professionally: Degaussing refers to the elimination of the magnetization of the display, and to understand degaussing, you must first know what magnetization is. What is commonly referred to as a display is magnetized, and what we see is an irregular color spot on the screen.
Magnetization is caused by the explosion-proof protective steel belt on the outside of the picture tube being approached by the surrounding magnetic materials (such as magnets, non-magnetic shielded speakers, etc.); Even if there is no magnetic material around, the prolonged action of the Earth's magnetic field is enough to cause the protective steel strip to be magnetized, just as a steel needle after being touched by a magnet is magnetic. Once the steel strip is magnetized, it will affect the normal deflection of the electron beam when the picture tube is working, resulting in the distortion of the image. (Due to the different working principles and structures--- liquid crystal displays are not affected by magnetic fields because there is no deflection scanning electron beam and no steel belt).
In order to eliminate the effects of magnetization, in fact, every time the display is turned on, the degaussing circuit will automatically activate to eliminate possible magnetization. The working principle of the degaussing circuit is to use an alternating magnetic field (obtained by 220V alternating current applied to the circuit of the degaussing coil in series with a thermally sensitive electric chain resistance) to eliminate the constant magnetic field that is magnetized by the pure hall. Some people say:
It cannot be degaussed frequently, it will be harmful. In fact, the inability to use degaussing frequently is not due to the adverse effects of degaussing on the display (basically none!). But there is no need for this!
Only in cases where the magnetization cannot be completely eliminated by each automatic degaussing, it is necessary to increase the degaussing effect manually to enhance the degaussing effect. Some articles mentions: "The degaussing coil has a charging process after degaussing, and if the interval between degaussing is too short and the coil cannot be fully charged, then the second degaussing has little effect."
In fact, after degaussing, there is not a charging process, but the thermistor connected by the degaussing coil needs to be cooled down to reduce the resistance back to the initial value to ensure that the degaussing coil works normally again, so it is correct that the necessary time interval is required for two degaussing.

The computer is often demagnetized badly and will damage the screen of the monitor! It is recommended to degauss when you notice a magnetic field on the monitor!
-
Good! The most recent CRT display is automatically demagnetized every time it is turned on.
-
That means you're about to have a problem with your monitor.

That's the CRT monitor.。。 Good for CRT...
Display degaussing.
Many displays have a built-in degaussing function, which can be performed by selecting the degaussing option from the control menu. When degaussing is performed, the display screen will shake violently, accompanied by a loud current sound, and after about a few seconds, the shaking and current sound will stop at the same time, and the degaussing will be completed. The degaussing function of the display has a good effect on the relatively weak magnetization, and it is also very convenient to use, but it has little effect on the deep magnetization caused by strong magnetic field interference. >>>More
What to do if the computer monitor has a blurred screen.
Troubleshooting steps: 1. Driver problems, which are also an important cause of blurred screens, mostly occur after changing the driver version of the graphics card, or may be caused by driver file corruption. The solution is very simple, reinstall and install the official graphics card driver. >>>More
