Screen tearing is a visual artifact that occurs when a display device shows information from multiple frames in a single screen draw, and the video feed to the device is not synchronized with the displays refresh rate. It is characterized as a horizontal split at one or more places in the image. During video motion, screen tearing creates a torn look as the edges of objects fail to line up, and it can occur with most common display technologies and video cards. Screen tearing is less noticeable when more than two frames finish rendering during the same refresh interval since that means the screen has several narrower tears, instead of a single wider one.

Screen tearing can occur when your monitors refresh rate and GPUs frame rate are not synchronized, and it can also occur if your frame rate is lower than the refresh rate of your display. There are a few different ways to fix screen tearing, depending on what features your graphics card and monitor support. Some of the ways to fix screen tearing include:

• VSync: This is the most common solution to eliminate screen tearing. VSync (Vertical Synchronization) syncs the frame rate of your GPU with the refresh rate of your monitor, but it can cause stuttering if your FPS often dips below your monitors maximum refresh rate.

• Adaptive VSync: This is a feature that dynamically turns VSync on and off depending on your FPS. It eliminates screen tearing and stuttering, but it requires a compatible graphics card and monitor.

• Enhanced Sync: This is an AMD technology that reduces screen tearing without the input lag of VSync. It works by allowing your GPU to render frames as fast as possible, but it only displays the most recently completed frame.

• Fast Sync: This is an NVIDIA technology that reduces screen tearing without the input lag of VSync. It works by allowing your GPU to render frames as fast as possible, but it only displays the most recently completed frame.

• FreeSync: This is an AMD technology that eliminates screen tearing by synchronizing the refresh rate of your monitor with the frame rate of your GPU. It requires a compatible AMD graphics card and monitor.

• G-SYNC: This is an NVIDIA technology that eliminates screen tearing by synchronizing the refresh rate of your monitor with the frame rate of your GPU. It requires a compatible NVIDIA graphics card and monitor.

• Variable Refresh Rate: This is a technology that eliminates screen tearing by synchronizing the refresh rate of your monitor with the frame rate of your GPU. It requires a compatible graphics card and monitor.

In conclusion, screen tearing is a visual artifact that occurs when a display device shows information from multiple frames in a single screen draw, and the video feed to the device is not synchronized with the displays refresh rate. It can be fixed by enabling VSync, Adaptive VSync, Enhanced Sync, Fast Sync, FreeSync, G-SYNC, or Variable Refresh Rate, depending on what your PC system and monitor support.
