3 Ways to Cut Your 32-Inch LED Monitor Energy Bill
- 🌱
Use dark mode on your OS and applications — on LED-backlit monitors, it still reduces eye strain and perceived brightness needs.
- 💡
Disable always-on USB hub ports on the monitor when not using connected devices.
- ⚡
Turn off the monitor with the physical button rather than relying on screen saver, which still draws full power.
LED monitors draw steady, consistent power with no startup surge beyond a momentary backlight initialization spike.
