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.
