# DimmerKun

‘DimmerKun’ is a multi-monitor-compatible screen brightness and dimness adjustment utility that allows you to dim your screen even further than the standard Windows brightness setting (0%).
It is ideal for reducing eye strain when working on your PC at night, or when gaming or watching films in a dimly lit room.

## ✨ Key Features

1. **Brightness adjustment beyond the limit**

   * By overlaying a black layer across the entire screen, you can adjust the brightness to a maximum of 97%, exceeding the monitor’s inherent limits.
2. **Individual settings for multiple monitors**

   * The programme recognises each connected display individually, allowing you to set different brightness levels for each monitor.
3. **Automatic scheduling function**

   * You can set a schedule to automatically switch to your chosen brightness level at a specified time (it also features a fade function that gradually dims or brightens the screen over time).
4. **Start-up rule settings**

   * You can set rules to automatically determine the initial brightness level based on the time of day when your PC or an application starts up.
5. **Useful Shortcuts & Control Features**

   * Supports an ‘emergency reset key’ for when the screen becomes too dim to operate, as well as intuitive fine-tuning using the mouse.

## ⌨️ Useful Controls & Shortcuts

### 🚨 Emergency reset (disable dimness) by pressing the ESC key three times in quick succession

If the screen becomes so dim that it is completely unreadable, **pressing the `ESC` key three times in quick succession** will immediately return the brightness of all monitors to ‘0’ (original brightness).

### 🖱️ Fine-tuning with the mouse wheel on the slider

By **scrolling the mouse wheel** over the brightness slider on the main screen, you can adjust the brightness intuitively and precisely in 2% increments.

### ⌨️ Confirm Input with the Enter Key

After entering a value directly into a numeric input box, pressing the `Enter` key confirms the value and moves the focus to the next field.
