FAQ

How do I stop tearing?

Enable adaptive sync (G-Sync/FreeSync) for tear-free, low-lag motion, or V-Sync to cap frames to the refresh rate (adds some lag). See our screen tearing guide for the full breakdown.

Tips

  • Use the vertical-bars frame for horizontal tears and the horizontal-bars frame for vertical tears.
  • Toggle V-Sync or adaptive sync (G-Sync/FreeSync) and watch the tear line appear or vanish.
