Automatic Refresh Rate Switcher

A small PowerShell utility for Windows laptops that automatically changes the display refresh rate when switching between AC power and battery power.

What It Does

• When the charger is plugged in, it switches the display to the configured refresh rate.
• When the charger is unplugged, it switches the display to another configured refresh rate.
• This makes it easy to use a higher refresh rate while plugged in and a lower refresh rate on battery to reduce power consumption.

Files

• refresh-rate.ps1 — Handles the refresh-rate change.
• setup.ps1 — Sets up the required configuration/tasks.
• switch.ps1 — Handles switching between the configured refresh rates.

Requirements

• Windows
• PowerShell
• A laptop/display supporting the configured refresh rates

Usage

Run the setup script:

.\setup.ps1
