Desktop Dimmer is a small utility app that allows you to reduce your screen brightness below the minimum level allowed by your system, which can be very useful for working at night or in low-light environments.

Here’s a breakdown of how to use and install it, based on the GitHub project by sidneys:

🔹 What is Desktop Dimmer?

🖥️ It’s a lightweight desktop brightness control tool.
💡 Lets you reduce brightness below the OS minimum by adding a black overlay.
⚙️ Cross-platform (Windows, macOS, Linux), built with Electron.

🔹 How to Install Desktop Dimmer

✅ 1. Go to GitHub Page

👉 https://github.com/sidneys/desktop-dimmer

✅ 2. Download Prebuilt Binary

The app may or may not still provide prebuilt releases. If they do:

Go to the Releases page.
Download the correct file for your OS:
- .exe for Windows
- .dmg or .zip for macOS
- .AppImage or .deb for Linux

❗ If no releases are available, you’ll need to build it from source (instructions below).

🔹 Option A: Run Prebuilt Version

Download and install the app like any standard program.
Run the app — it will add an icon to your system tray.
Use the tray menu to adjust brightness.

☕ Note: Desktop Dimmer does not adjust the hardware backlight — it places a transparent dark overlay on top of your screen.

🔹 Option B: Build from Source (If No Releases)

📦 Prerequisites:

Node.js (with npm)
Git

📥 1. Clone the repo:

git clone https://github.com/sidneys/desktop-dimmer.git
cd desktop-dimmer

🛠️ 2. Install dependencies:

npm install

🚀 3. Start the app:

npm start

That will launch the app locally.

🔧 Features

Adjust brightness via system tray icon
Launch on startup (optional)
Set different levels for multiple displays
Cross-platform compatibility

🧯 Known Issues or Limitations

May interfere with screen capture tools (since it overlays a black layer).
Might not work well with fullscreen apps or games.
Not a substitute for adjusting actual screen backlight (which saves battery on laptops).
