Screen Tearing: Frame Sync, Refresh Rates, and G-Sync Fixes
Screen tearing is a visual distortion where horizontal split seams cut across your display during camera movement. It occurs when your graphics card sends new frame data mid-scan, causing the monitor to display portions of two different frames simultaneously.

What Screen Tearing Looks Like During Motion
When panning the camera rapidly in a first-person game or scrolling high-speed video, you may see the top half of the screen shift slightly to the left or right while the bottom half lags behind.
This horizontal "tear" line marks the exact point where the display hardware refresh scan was interrupted by a new buffer swap from your computer graphics card.
The Core Cause: GPU Frame Production vs Monitor Refresh Desynchronization
A monitor updates its picture sequentially from top to bottom at a fixed rate (e.g., 60 times per second for 60Hz, or 144 times per second for 144Hz).
A graphics processing unit (GPU), however, renders frames dynamically depending on scene complexity. If your GPU outputs 85 frames per second on a 60Hz monitor, it pushes frames faster than the monitor can draw them. The monitor is forced to draw frame #1 on the top half and frame #2 on the bottom half, creating a tear.
How to Distinguish Screen Tearing from Motion Ghosting
While both tearing and ghosting degrade motion clarity, their visual characteristics and remedies are fundamentally different:
| Screen Tearing (Synchronization Issue) | Motion Ghosting (Pixel Speed Issue) |
|---|---|
| Visual appearance: Sharp horizontal cuts or split seams | Visual appearance: Soft blurry trails behind moving objects |
| Cause: Frame rate not synced with monitor refresh | Cause: Liquid crystal transition response time (GtG) too slow |
| Where it happens: Any panel type (OLED, IPS, VA, TN) | Where it happens: Primarily slow LCD panels (especially VA) |
| Solution: Enable V-Sync, G-Sync, or FreeSync | Solution: Adjust monitor overdrive setting (AMA/Trace Free) |
| Hardware limitation: No panel defect involved | Hardware limitation: Physical panel response time ceiling |
Synchronization Solutions: V-Sync, G-Sync, FreeSync, and Variable Refresh Rate
There are three primary technologies designed to eliminate screen tearing entirely:
- •V-Sync (Vertical Synchronization): Forces the GPU to hold rendered frames in a buffer until the monitor finishes its complete refresh cycle. While it eliminates tearing, it introduces input lag and causes stutter if FPS drops below monitor refresh rate.
- •G-Sync (NVIDIA) & FreeSync (AMD): Variable Refresh Rate (VRR) technologies that make the monitor refresh rate dynamically match the exact FPS of your graphics card. This eliminates both tearing and stutter with zero perceptible input latency.
- •FastSync / Enhanced Sync: Discards torn frames while allowing the GPU to run unconstrained, reducing input lag while eliminating horizontal tears.
Recommended In-Game and Driver Settings for Fluid Motion
To achieve perfect tear-free motion on high-refresh gaming displays:
Screen tearing is purely a frame timing handshake issue between your operating system, graphics driver, and monitor refresh pipeline. Your monitor is not defective; configuring proper synchronization settings will permanently solve the problem.
Do not RMA a monitor for screen tearing. Simply configure G-Sync, FreeSync, or frame rate caps in your graphics settings.

Frequently asked questions
Does screen tearing happen if my FPS is lower than my refresh rate?
Yes. Tearing occurs whenever frame rendering is unsynchronized, whether FPS is above or below your refresh rate.
Does capping FPS eliminate the need for G-Sync?
No. Capping FPS limits how many frames are rendered, but does not align the frame scan timing with monitor refresh cycles. G-Sync or FreeSync is still required for zero tearing.

A hot pixel is a pixel whose red, green, and blue subpixels are all simultaneously frozen at maximum output, resulting in a persistent, bright white pinpoint that glares noticeably against dark scenes and black backgrounds.
Backlight bleed is a hardware assembly issue where light from the monitor internal LED backlight escapes past the edges or corners of the liquid crystal panel, creating localized flares of yellow or white light across dark screens.
