What Is Screen Tearing and How to Fix it

What Is Screen Tearing and How to Fix it

Stephen Mash
When using computer displays for visually intensive applications such as gaming or watching films, getting the best out of your monitor can positively enhance your viewing experience. However, suddenly seeing blurring or disjointed images across the screen can be annoying, particularly if you're in the middle of playing the latest triple-A release with your friends.
This article aims to explain the phenomenon of screen tearing, an issue that impacts computer displays. We'll briefly explain what this effect is, how to recognise it on your monitor, and offer solutions should you find you are affected.

What is Screen Tearing?

Screen tearing is an effect seen in moving pictures where the display suffers from distortion due to incorrect rendering of fast-changing images on the screen. Depending on the nature of the visual artefact, this may appear as a short-lived distracting glitch or a persistent distortion that can cause eye strain. In all cases, the overall effect is to disturb the visual experience and distract the viewer.

What Causes Screen Tearing?

There are two leading causes for screen tearing effects: configuration issues between the graphics processor unit (GPU) generating images and the monitor that displays them.
  • A disparity between the frame rate of computer-generated images and the monitor's refresh rate that displays those images can be one cause. A significant difference between these two rates can result in image artefacts appearing when the computer-generated image frames change while the screen completes one display cycle. The difference between the two rates will determine the size and scale of the screen tearing distortion and how long it persists.
  • Screen tearing can also occur when there is a match between the frame rate of computer-generated images and the monitor's refresh rate that displays those images. A lack of synchronisation between the computer generation of images and their display can distort a fixed point on the monitor. The phase difference between the start point of the source frame generation and the start point of the display refresh determines the position of the distortion. Any slight differences between the frame rate and refresh rate will result in the movement of the screen tearing artefacts up or down the screen.
Synchronisation issues may be caused by operating a GPU beyond its standard capabilities.
For example, it cannot maintain the required frame rate or generate more frames than the connected monitor. These problems occur in image-intensive gaming applications that require a high frame rate to deliver responsiveness. In addition, issues in the performance of the GPU, or insufficient GPU memory, can create throughput bottlenecks that generate screen tearing effects.

How to Spot Screen Tearing

The most typical example of screen tearing is a horizontal line across the display screen where the picture above the line does not precisely fit with the picture below the line. As a result, the two images are horizontally offset, which can appear as a subtle blurring or, in extreme cases, a disjointed picture. In all cases, the effect is distracting and detrimental to the viewing experience.
Under some conditions, screen tearing may appear at multiple points on a screen. A vertical line displayed on the screen will appear to have several breaks along its length where the line shifts horizontally.
The most common situation where screen tearing occurs is when the image moves horizontally, such as in games where players scan their eyes around a room. This scrolling movement amplifies the visual impact of any screen tearing effects.

How to Fix Screen Tearing

How to Fix Screen Tearing
If you are experiencing display issues, here are a few suggestions for how to fix screen tearing.
  1. The first step to resolving screen tearing effects is to adjust the display resolution and refresh rate to ensure they are compatible with the settings for the computer's GPU. The display resolution should match the GPU output resolution. In addition, you should set the display refresh rate to its maximum value. Adjusting the resolution and refresh rate can resolve screen tearing issues quickly and effortlessly.
  2. The next step is to check the graphics drivers on your computer system, ensuring that the latest available drivers are installed and correctly configured. More information is available online for each specific driver. Also, if the screen tearing effects have suddenly appeared following a system update, check if the issue is due to an incompatibility with the latest version of the display driver. The simplest method of checking is to download and install an older driver version to eliminate this possibility.
  3. For computer systems with a graphics processor connected to a display that both support the AMD® FreeSync™ function, this adaptive synchronisation technology can eliminate tearing effects. If this function is enabled but screen tearing effects are present, this may be due to compatibility issues between the processor and the display. In this case, disabling the AMD FreeSync function may resolve the issue.
  4. For computer systems that use the popular and capable NVIDIA® technology to create graphics, adjustment of the G-SYNC™ function can help resolve screen tearing issues. NVIDIA designed G-SYNC to eliminate ghosting and tearing effects. It achieves this by dynamically managing display refresh synchronisation when connected to a compatible display. Therefore, where the G-SYNC function is enabled when screen tearing effects are present, disabling the G-SYNC function may resolve the issue if the connected display is not fully compatible.
  5. For windows-based computer systems, the smooth scrolling function can interfere with the operation of the GPU. This feature manages the graphics frame rate depending on the computer's usage. Disabling smooth scrolling can resolve these issues.
  6. The cause of screen tearing may also be down to the gaming software generating the graphical outputs using a GPU. Where games use a frame limit function to manage GPU loading, this can unintendedly cause tearing artefacts. If you only observe screen tearing with a particular game, disabling frame limiting may be the answer if the GPU can handle the higher frame rates and loading.
  7. The power settings used to manage battery life can affect graphical processing performance and cause screen tearing effects for mobile devices such as tablets and laptops. Ordinarily, such devices offer a high-performance setting in the power options that maximises processing performance at the expense of power usage. This setting ensures that any graphical processing is not constrained and can eliminate screen tearing resulting from graphics processor throttling.
These solutions attempt to eliminate graphics issues, including screen tearing resulting from configuration problems in the existing equipment. If the problem is down to the display monitor's inability to handle your graphical demands, the only solution will be a display upgrade.
