The display is shaky

Guess your monitor uses Sony's Trilon CRT, which is a shade grid CRT that arranges phosphors into straight strips that span the entire screen, and the shade hood is changed to a strip shade grille, which consists of an array of parallel vertical wires fixed in a very tensile iron frame. This fence leads from the top of the screen to the bottom of the screen, rather than a fluorescent dot. Because there is only one electron gun, but it can shoot 3 electron beams, which pass through the grid and hit the fluorescent strip to make it glow, so it is also called "single gun and three beams" picture tube.

One of the drawbacks of the shadow grid CRT is that the vertical grid is not like a mesh grid, which has an infinite number of connections in between. It leads from the top of the screen to the bottom of the screen, if there is no support in the middle, it is easy to be seriously deformed like a wicker fluttering in the wind, therefore, it is necessary to use one or two horizontal thin grid bars in the middle of the grid to fix and support, but it is still easy to have the problem of display screen shaking when it is shaken. In addition, some displays have quality problems such as virtual soldering and poor component contact, which can also lead to similar phenomena.

It's normal. It means that the quality of your monitor is not very good.

Let me tell you,The display has been around for a long time,It's all like this,If you just bought it, it's like this,You have to be careful.,Maybe it's not new.,Be sure to find js to change!

There is virtual soldering on the display circuit board.

I have repaired such a fault in Meig, it is that there is a relay virtual welding in the secondary of the switching transformer, and it is good to weld it, and the screen will be black when the virtual welding is serious.

It's not your monitor, it's that your computer isn't set up, one is that the graphics card refresh rate is set low, the second is that your monitor is better not to be close to the speaker, and the third is that your system is wrong.

Hello. The causes of the malfunction you mentioned are as follows.

The monitor refresh rate is set too low.

When the refresh rate of the display is set to be lower than 75Hz, the screen often shakes and flickers, so adjust the refresh rate appropriately, such as setting it higher than 85Hz, and the screen shaking will generally not appear again.

The power transformer is too close to the monitor and chassis.

When the power transformer is working, it will cause large electromagnetic interference, which will cause the screen to shake. Keeping the power transformer away from the chassis and display can solve the problem.

Inferior power supplies or power supply equipment are aging.

The workmanship and materials used in many miscellaneous computer power supplies are very poor, which can easily cause the circuits of the computer to be poor or the power supply capacity can not keep up, and when the system is busy, the display will especially appear screen shaking. When the power supply equipment of the computer starts to deteriorate, it is easy to cause the same problem.

The speakers are placed too close to the monitor.

The magnetic field effect of the speaker will interfere with the normal operation of the display, causing the display to produce magnetic interference phenomena such as screen shake and color crossing.

Viruses do the trick. Some computer viruses can disrupt the screen display, such as: character inversion, screen shaking, graphic flipping display, etc. The ubiquitous screen shake scripts on the internet are enough to make your head as big as a cow after a hit.

The graphics card is not in good contact.

After the graphics card is reinserted, the fault can be troubleshooting.

Win95 98 system after write cache caused.

If this is the case, disabling all drive write-back caching in Control Panel - System - Performance - File System - Troubleshooter will resolve the problem at all.

The power filter capacitor is damaged.

Open the case, and if you see the top of the power filter capacitor (the largest capacitor on the board) bulging up, then the capacitor is broken, and the screen shake is caused by a power failure. Once the capacitor is replaced, the problem can be solved.

Hehe, there is a virtual solder on the circuit board of the monitor, go find someone to fix it.
