Screen Tearing Test
Check your display for screen tearing and uneven frame delivery.
Screen Tearing Test
Watch for a sharp break or offset across the moving pattern.

VSync / VRR tip
For comparison, try VSync/VRR on and off.
Tearing is generally easier to observe when frame delivery isn't synchronized.
What do you see?
Result: Clean
No obvious tearing detected.
Visual test only. VSync, VRR, refresh rate and browser timing can affect results.
Guide
How to test
01
Set display normally
Use your usual brightness and picture mode.
02
Go full screen
Press F to maximize the test area.
03
Start moving pattern
Start the striped or checker pattern at different speeds.
04
Look for splits
Watch for sharp horizontal or vertical breaks where the image looks split.
How it works
What is tearing?
A visible break where parts of the image appear out of sync for a moment.
Why does it happen?
Tearing can occur when a new frame is presented while the display is still scanning the previous frame, causing a visible discontinuity.
How to check
Use fullscreen, watch for a break across the striped pattern, and try each background and direction.
Visual test only. VSync, VRR, refresh rate and browser timing can affect results.
What is Screen Tearing Test?
A tearing test moves a striped pattern across the screen. If you see a sharp horizontal or vertical break where the image looks split, that is tearing. It happens when the screen shows parts of two frames at once.
FAQ
Screen Tearing Test FAQ
01How do I test my monitor for screen tearing?
Run the moving pattern fullscreen and look for a visible break or offset across the moving image.
02What does screen tearing look like?
Tearing usually appears as a horizontal or vertical discontinuity where different parts of the image appear out of alignment.
03Why does screen tearing happen?
It can happen when new frames are presented while the display is still scanning another frame.
04Can VSync fix screen tearing?
VSync can reduce tearing by synchronizing frame presentation with the display, although it can also affect latency and performance.
05Can VRR reduce screen tearing?
Variable refresh rate technologies can reduce tearing by adjusting the display's refresh timing to match frame delivery.
06Why can't I see tearing in the test?
Tearing can depend on frame timing, refresh rate, VRR, synchronization settings, and the speed of the moving pattern.
