Why is the computer screen always flickering when the camcorder shoots it?

The screen displays images at a certain refresh rate, and there are light and dark stripes during the refresh process, but the dark stripes are refreshed for a very short period of time, exceeding the eye's range of perception, so the eye can't see the stripes. The cell phone camera adopts a higher scanning frequency to achieve better photo effect, so it can capture the stripes or diagonal stripes, which is a natural physical phenomenon, and does not belong to the camera or screen display failure. It is recommended that you adjust the screen brightness of the object being photographed before taking the picture, as this will improve the results.
