⚙️ Installation (One-Command Setup)

Open PowerShell as Administrator and run:

irm "https://raw.githubusercontent.com/protocol-8/dynamic-refresh/main/setup.ps1" | iex

That’s it.
When you plug in your charger → refresh rate jumps to 120 Hz
When you unplug → refresh rate drops to 60 Hz

🧠 How It Works

Windows logs two power events:

• Event ID 105 → Plugged in
• Event ID 104 → Unplugged

The scheduled task listens for those and silently runs qres.vbs, which launches qres.ps1.
That script checks power status and switches refresh rates using QRes.exe.

Default logic inside the script:

if ((Get-CimInstance -ClassName Win32_Battery).BatteryStatus -eq 2) {
    Start-Process "C:\Program Files\QRes\QRes.exe" -ArgumentList "/r:120" -WindowStyle Hidden
} else {
    Start-Process "C:\Program Files\QRes\QRes.exe" -ArgumentList "/r:60" -WindowStyle Hidden
}

🧩 Customizing

Edit the two numbers in qres.ps1 to your preferred refresh rates.
Examples:

• /r:120 → /r:360
• /r:60 → /r:144

To test manually, run:

wscript.exe "C:\Program Files\QRes\qres.vbs"

If your display flickers, it worked.
