Digital clocks may 'wiggle' due to your screen's refresh rate. This phenomenon, called aliasing, occurs when the digital display's refresh rate is slightly out of sync with the screen capturing it, causing a seeming movement or flicker. To avoid this, try adjusting your screen's refresh settings or use a different screen to view the clock.

  2. How can I stop my digital clock from wiggle? To stop your digital clock from wiggling, adjust your screen's refresh rates or use a different display to view the clock.
  3. Is the wiggling effect harmful? No, the wiggling effect is purely visual and does not harm the digital clock or the screen.
