Screen flicker on the monitor

The display screen flicker is a common situation in which users use computers, where the screen flashes differently and the problem is different from the solution.

1. The edge of the screen flashes or the entire screen flashes. This fault is generally due to the circuit part of the virtual welding or power supply at the +300v filter capacitance reduction caused by the former is more likely, the latter generally will not appear. In addition, this can be caused by the high or low resolution and refresh frequency settings. If there is a problem with the video card or the monitor driver, you should update the driver first. If none of the above can be solved, we should focus on checking if the voltage generated by the high-pressure package is normal.

2. There is a flicker phenomenon in the corner of the screen. Sometimes some magnetic items are placed in the display attachment, which can cause a corner of the screen to blink. So this situation, first the display around the object removed, or degaussing processing, usually can solve the fault.
