Understanding and Fixing Screen Tearing in Gaming
Key points
- Screen tearing results from GPU frame rate and monitor refresh rate mismatch.
- GPUs can render frames faster or slower than a monitor's refresh rate.
- Monitors have fixed refresh rates (Hz), while GPUs output frames per second (fps).
- Technologies exist to synchronize GPU and monitor, resolving screen tearing.
What is Screen Tearing?
Screen tearing is a visual artifact where a display shows parts of multiple frames simultaneously, creating a jagged, broken image. This phenomenon is most frequently encountered in PC gaming but can also affect console gaming experiences.
Causes of Screen Tearing
The primary cause of screen tearing is a desynchronization between the rate at which a computer's GPU renders video frames and the rate at which the display refreshes to show those frames. A GPU might render frames much faster than a monitor's refresh rate, or significantly slower under heavy load.
Monitors refresh at a fixed rate, measured in hertz (Hz), while GPUs produce frames per second (fps). When a new frame is rendered by the GPU into the buffer before the monitor has completed scanning the previous frame, parts of both frames can appear on screen, causing the tear.
Monitor Refresh Rates and GPU Output
Standard monitors typically have a refresh rate of 60Hz. Gaming monitors offer higher refresh rates, such as 144Hz or 240Hz, with some newer models reaching 1,000Hz. These higher rates make individual refresh cycles less perceptible. Despite advancements in monitor technology, the fundamental mismatch between GPU output and monitor refresh can still lead to tearing if not addressed by synchronization technologies.
Solutions to Screen Tearing
Screen tearing is a solvable problem due to technologies designed to coordinate frame delivery between the graphics card and the monitor. These solutions aim to synchronize the GPU's frame output with the monitor's refresh cycles, preventing the display from showing incomplete frames.

Reporting from
Screen tearing occurs when a graphics processing unit (GPU) renders frames at a different rate than a monitor displays them, leading to visual artifacts. This issue, common in PC gaming, can be resolved through technologies that synchronize frame delivery between the GPU and monitor.
