Display Dimmer
Dims Windows displays via monitor hardware, falling back to software gamma when that fails.
Display Dimmer controls brightness and contrast on Windows laptops and external monitors, using each display's own DDC/CI hardware control when supported and falling back to software gamma dimming when it isn't — it tracks failures per display and switches automatically. The free tier covers brightness, contrast and 30 minutes of color-temperature preview a day; a $5.99 one-time Pro upgrade removes that cap and adds unlimited schedules, app-based rules, per-display automation and command-line control. It's rated 4.9 from 243 Microsoft Store reviews across 80,000+ installs, with a Mac version still in beta signup.
What holds up
- +Falls back to software gamma dimming automatically when a monitor's DDC/CI hardware control fails.
- +One-time $5.99 Pro upgrade, no subscription — and the free tier already covers basic brightness control.
- +4.9 stars across 243 Microsoft Store ratings and 80,000+ installs, a real track record, not a launch claim.
Mind the limits
- −Windows only for now — the Mac version is still a beta waitlist, not a shipped product.
- −Free tier caps color-temperature control at 30 minutes a day; unlimited needs the Pro upgrade.
- −Hardware brightness depends on your monitor and connection supporting DDC/CI, which isn't guaranteed.
