A downloadable tool

Dimmer lets you adjust brightness, contrast, gamma, and color balance per monitor or per app, then toggle the effect instantly with global hotkeys. 

Use it to lift shadow detail in dark games, reduce glare, or dial in a comfortable look without touching your GPU control panel. It's not a filter, doesn't reduce FPS.

It supports presets (save and swap profiles), a Guide tab with setup tips, and per‑row pin/unpin for quick app targeting.

 Portable and lightweight.
