Monitor Brightness

Control your external monitor's brightness right from your Stream Deck +. Turn a dial to dim or brighten the display by a step you choose (1–25% per click). Tap the touch strip or press the dial to jump straight to 100%, or hold it to drop to 0%. The touch strip shows the current brightness with a live percentage and progress bar.

Features

- Dial rotation adjusts brightness by a configurable step

- Tap or press: 100% brightness

- Hold or long-tap: 0% brightness (hold time adjustable)

- Control all monitors at once or pick a single monitor per dial

- Custom title on the touch strip

- Fast rotation is handled smoothly and verified against the monitor, so the display always ends up at the value shown

- A warning icon appears on the dial if the monitor does not respond

Requirements

- Windows 10 or 11, Stream Deck 6.9 or later, Stream Deck +

- An external monitor with DDC/CI enabled in its on-screen menu (developed and tested with an Alienware AW2524HF)

- No extra software needed: brightness is set through the Windows monitor API

Tips

If brightness does not change, make sure DDC/CI is turned on in your monitor's menu. Some docks and adapters do not pass DDC/CI through, and features like dynamic contrast or HDR modes can lock brightness.
