3 Ways to Cut Your 24-Inch LED Monitor Energy Bill

  • 🌱

    Reduce brightness from the default (often 80–100%) to 40–50% — this can cut the monitor's power draw in half.

  • 💡

    Enable the auto-brightness sensor if available, so the monitor dims in low-light environments automatically.

  • Set the sleep timer to 3 minutes so the monitor powers down quickly when you step away.

Startup Surge Information

LED monitors use stable resistance-based backlighting with no motors, so power draw is consistent with no surge.
