What is screen tearing and how does it occur?
Screen tearing is a visual artifact that occurs when a display shows information from multiple frames in a single screen draw. This happens when the graphics card renders frames at a rate that is not in sync with the monitor’s refresh rate. As a result, the display shows a tear or a horizontal line where the two frames meet, creating a distorted image. Screen tearing can be particularly noticeable in fast-paced games or videos, where the graphics card is rendering frames quickly.
The occurrence of screen tearing is often due to the lack of synchronization between the graphics card and the monitor. When the graphics card renders a frame, it is stored in the video memory buffer. If the monitor is not ready to display the new frame, the graphics card will start rendering the next frame, which can cause the tearing effect. To prevent screen tearing, graphics cards and monitors use various synchronization technologies, such as VSync (Vertical Sync) or G-Sync, which help to ensure that the frames are rendered and displayed in sync with the monitor’s refresh rate.
Is screen tearing harmful to my display?
Screen tearing is not directly harmful to your display. It is a visual artifact that can be annoying and affect your viewing experience, but it does not cause any physical damage to the display.
