Screen Tearing Test
Check whether fast horizontal motion produces visible tears or broken lines on your display when frame rate and refresh rate are out of sync.
How to recognize tearing
Tearing appears as one or more horizontal breaks where parts of different frames are shown at the same time. It is often easiest to spot on fast moving vertical lines or scrolling motion.
Use this test while comparing V-Sync, G-Sync, FreeSync or frame-rate limit settings. A clean result usually means frame delivery is matching the display refresh more closely.
- A broken line or visible split across the image is a classic tearing sign.
- Tearing can change depending on frame rate, refresh rate and adaptive sync settings.
- Test both fullscreen and windowed modes if your setup behaves differently.
- On mobile devices, tap the screen once or twice to reveal controls and move between steps.
How to read the result
Use the focused test first, then confirm what you see on at least one or two additional steps. A single quick glance can be misleading on glossy panels, OLED screens or displays with strong reflections.
- Clean the panel surface before you decide that a defect is real.
- Check from your normal viewing distance first, then move closer.
- Retest with another related tool if the issue could also be caused by uniformity, sync or motion settings.
- If you are within the return window, take notes or photos while the issue is still easy to reproduce.

Frequently asked questions
Screen tearing happens when the graphics output and monitor refresh are not synchronized, so parts of different frames appear on the screen at the same time.
V-Sync often reduces tearing, but it can also add latency or stutter in some situations. Adaptive sync options such as FreeSync or G-Sync may provide a better balance.
Higher refresh rates can reduce how obvious tearing looks, but they do not eliminate it if frame delivery still falls out of sync.
Yes. A browser-based tearing test is useful for a quick visual check before you fine-tune game settings and graphics driver options.
