Sometimes flashing, sometimes not flashing, the problem is on the top
Here is your monitor hardware problem. Check your monitor at the professional maintenance office.
I think it's a question of frequency. Adjust it for a little bit
Causes of display jitterThe display refresh rate is set too lowWhen the display refresh frequency is set below 75Hz, the screen will often appear jitter and flicker phenomenon, the refresh rate is appropriately increased, such as set to higher than 85Hz, the phenomenon of screen jitter will not occur any more.The power transformer is too close to the monitor and the caseWhen the power transformer works, it will cause greater electromagnetic interference, resulting in jitter of the screen. Put the power transformer away from the cabinet and monitor, so that the problem can be solved easily.Inferior power or power supply equipment has been agingThe use of many brand-name computer power components work, the materials used are very poor, easy to cause the computer circuit or poor power supply capacity can not keep up, especially when the system is busy, the display screen will appear the phenomenon of jitter. When the power source of a computer starts to age, it can cause the same problem.The speakers are too close to the monitorThe magnetic field effect of the speaker interferes with the normal operation of the display, and causes the display to cause magnetic interference such as screen jitter and string color.Virus troubleSome computer viruses disrupt screen displays, such as character inversion, screen jitter, graphical flip displays, and so on. Screen shake scripts that are everywhere on the Internet are enough to make you look like an ox after you get caught.Poor contact with the display cardAfter re insert the display card, the fault can be eliminated.
In addition to adjust the screen refresh Hz (60 Hz) and teach you a simple way, because now the graphics on screen now too old, as long as you can put down the display resolution. PS: my monitor has been adjusted to 1280X800
