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.

Startup Surge Information

LED monitors draw steady, consistent power with no startup surge beyond a momentary backlight initialization spike.
