The wait's over. The GammaBoost+ Demo is live on Steam right now — and you've got 7 days to try every feature before launch on June 22, 2026.
➡️ Install the Demo on Steam
➡️ Wishlist GammaBoost+ for launch
What's in the Demo
The demo is the full app. Not a stripped-down preview, not a trial-with-features-locked. Every preset, every slider, every profile — all of it, for 7 days.
- One-click gamma presets — tuned for eye care, color matching, gaming, late-night reading, and streaming.
- Precision sliders — gamma, brightness, contrast, RGB channels, vibrance, color temperature, black level, tint, highlights, and a draggable custom tone curve.
- Per-app profiles — GammaBoost+ detects which app you launched, applies your saved profile, and reverts when you close it.
- Global hotkeys — flip gamma on/off, cycle presets, or jump to a profile with any keybind or mouse button. Works while any app is fullscreen.
- Eye-care mode — reduce blue light and dim below the Windows minimum.
- OBS WebSocket sync — your stream's color filter mirrors your on-screen settings in real time, plus .cube LUT export for Premiere, DaVinci Resolve, and Final Cut.
- Community presets — browse and download gamma configs shared by other users.
- Multi-monitor support — adjust each display independently.
