HDRToggler

AutoHotkey v2 script that toggles HDR in Windows 10 using HDRSwitch by cocafe

🌟 Features

• Detects current HDR state on launch
• Toggles HDR on/off via tray click, tray menu, or hotkey (Ctrl + Alt + H)
• Dynamic tray icon updates based on HDR status
• Comes with a precompiled HDRToggler.exe for users who don’t want to install AutoHotkey
• Comes with a precompiled HDRSwitch.exe for thos who can't or won't compile C, C++

📦 Requirements

• Windows 10 (Windows 11 users have other options built into the OS and on GitHub)
• HDRSwitch.exe (precompiled .exe included here for convenience)
• HDR-capable monitor (not really required to run but you'll just be toggling hot air otherwise)

🔧 Installation

1. Download this repo and place HDRSwitch.exe in the same folder.
2. Run either:
   • HDRToggler.ahk (if you have AutoHotkey v2 installed)
   • HDRToggler.exe (if you don’t want AutoHotkey — it’s precompiled for convenience)
3. Use Ctrl + Alt + H, left-click the tray icon, or use right-click tray menu to toggle HDR.
4. Create shortcut and place in startup folder to run on windows boot.

Notes

• This script creates a small 1KB file [hdrlog.txt] to read monitor status which is overwritten with each toggle (no bloat).
• This script expects that Monitor 0 (based on output from "HDRSwitch.exe --list") is your HDR capable monitor. Check hdrlog.txt and modify script accordingly
