How the monitor determines and removes the stain

The main symptoms of the monitor being magnetized are: There are some areas where the color spots, the local image is dark or the color becomes lighter. If the picture tube is magnetized the symptom is lighter, you will find the monitor appears to have the dust, but with the finger a rub and no traces of dust. If the magnetization is more serious, you will see the display of a certain area of the colorful color spots. Sometimes, you may see a spot on the monitor that has a lighter local color, which may be the performance of the Tube's shroud being magnetized.

The easiest way to detect if a monitor is magnetized is to use Word software, the default white background in Word makes it easy to find subtle changes in the local color of the screen, which may be the result of contact between the Monitor's signal line or the display card and the motherboard slot, or the magnetization. You can try to move the monitor signal cable and power Plug and unplug the display card to determine. If there is no change, it must be the picture tube has been magnetized.

The display is magnetized mostly because the display has a magnetic field around the device to the picture tube has a magnetized effect, such as computer speakers, microphones, stereos and so on. Under normal circumstances, the computer's dedicated speakers are magnetically treated, it will not be magnetized display, but inferior speakers may have magnetic leakage phenomenon. It is common that some speakers of the side or after the face of the display has a certain magnetic effect. If you find that the display may be magnetized, the easiest way is to move the display around 20 centimeters apart from the chassis, keyboard, mouse, and anything that may be magnetic.

The method of eliminating the magnetization of the picture tube is not too complicated and can be solved by oneself. For the relatively light of the intensity of the display through the machine itself with the degaussing function can be solved. More than 15-inch and more automatic degaussing function, such as the OSD menu of Samsung Monitor has degaussing menu, select it, the monitor screen a jitter, degaussing process is completed. However, you may need to press the degaussing button several times to remove the abnormal color completely.

If the monitor is magnetized more seriously, the above method can not completely solve the problem, it needs to use a special tool-degaussing stick to solve. Degaussing Stick is the use of magnetic induction principle, through the coil of alternating current in the geometric center of the loop to produce an alternating magnetic field, the cathode of the display to degaussing, so as to achieve the purpose of degaussing. Handheld degaussing stick in front of monitor screen with the center of the screen centered, the radius of the gradual amplification of the circular motion, at the end, the degaussing rod placed in the center of the screen, and the screen surface into a 90-degree angle, keep the vertical slowly back to the monitor 1m, and then turn off the power, reboot. Observe the degaussing effect carefully. If the effect is not good, can be repeated, until completely eliminate the display due to magnetization caused by the abnormal phenomenon.
