What is the reason for Screen Tearing?

Question

Video cards

I would like to know the essence of the emergence of Screen Tearing, as well as understand the system for processing an image by a video card and output. Can this effect occur when the monitor's refresh rate is higher than the graphics card's image processing rate?

Answer 1

May appear. The most important thing is that they are synchronized with each other, then they will not appear. This is called vertical sync .
