Monitor refresh rate is set too low

When the display of the refresh frequency set below 75Hz, the screen will often appear jitter, flashing phenomenon, the refresh rate appropriate, such as set to higher than 85Hz, the phenomenon of screen jitter generally does not appear again.

Power transformers are too close to the monitor and chassis

The power transformer will cause large electromagnetic interference when it works, thus causing the screen jitter. Put the power transformers away from the chassis and the monitor so that the problem can be solved.

Poor quality power or power device is aging

Many of the computer power use of the components of the work, materials are very poor, easy to cause the computer circuit is not smooth or power supply ability to keep up, when the system is busy, the monitor will appear in particular the phenomenon of screen jitter. When the computer's power device starts to age, it is also easy to create the same problem.

The speaker is too close to the monitor.

The magnetic field effect of the speaker will interfere with the normal work of the display, causing the screen jitter and string-color magnetic interference phenomenon.

Virus Mischief

Some computer viruses will disturb the screen display, such as: character inversion, screen jitter, graphics flip display. The screen jitter scripts that are ubiquitous on the web are enough to make you a big bull in the middle.

Bad contact with the display card

The failure can be eliminated after reseating the display card.

WIN95/98 system post-write cache causes

For this reason, the write cache is disabled in the Control Panel-system-performance-File system-Troubleshooter, allowing for a fundamental solution to the problem.

Power Filter Capacitor damage

Open the chassis, if you see the Power filter capacitor (the board of the largest capacitor on the top), then the capacitance is broken, the screen jitter is caused by power failure. After changing the capacitor, you can solve the problem.
