GammaBoost+

Take control of your display

GammaBoost+ is a Windows display utility for people who spend a lot of time in front of a monitor. Whether you're editing late at night, streaming, working across multiple displays, or just want your games to look the way they should — GammaBoost+ gives you real-time, per-monitor control over gamma, color, brightness, and contrast.

It's not a filter. It's not an overlay. It's the same OS-level gamma ramp Windows already uses for Night Light — just with deep slider control, one-click presets, per-application profiles, and a hotkey for everything.

Who it's for

• Late-night users & eye care — Dim past what Windows allows, warm your screen beyond Night Light's limits, switch modes with a hotkey. Reduce blue light without losing readability.

• Accessibility — Built with low-light vision difficulty, color sensitivity, and screen fatigue in mind. Large sliders, clear labels, full hotkey operation if you prefer not to touch the UI.

• Streamers & content creators — Sync your color settings to OBS via WebSocket so viewers see what you see, not a too-dark broadcast. Export .cube LUTs for Premiere, DaVinci Resolve, or Final Cut.

• Multi-monitor setups — Adjust each display independently. Match an HDR panel to an SDR panel side-by-side. Tune a secondary monitor for color-sensitive work while leaving your main screen untouched.

• Gamers — Lift shadows in atmospheric games, warm the picture in horror titles, push vibrance in racing sims, or rebalance gamma for older titles that ship too dark.

What's in the app

• One-click presets — High Contrast, Shadow Boost, Forest Ops, Extraction Mode, Cool Boost, Warm Boost, Night Mode, Soft White, and more. Mix and match per profile.

• Precision sliders — Gamma, brightness, contrast, RGB channels, vibrance, color temperature (1000K–10000K), black level, tint, highlights, and a custom tone curve.

• Global hotkey toggle — Flip gamma on/off, cycle presets, or jump to a specific profile with any keybind or mouse button. Works while any app is fullscreen.

• Per-application profiles — GammaBoost+ detects which app or game you've launched and applies your saved profile automatically. Reverts cleanly when you close it.

• OBS WebSocket sync — Your stream's color filter mirrors your on-screen settings in real time, so what your viewers see matches what you see.

• Community profile sharing — Browse user-submitted profiles, download what you like, share your own.

• Multi-monitor support — Pick which display to adjust. Works with any monitor that supports the standard Windows gamma ramp.

• Eye-care mode — Reduce blue light and dim below the Windows minimum, layered on top of any preset.

• Steam Cloud sync — Profiles and keybinds follow you to any machine you sign into.

• Available in your language — Localized across English, Spanish, French, German, Portuguese, Japanese, Chinese, Korean, Russian, and Turkish.

How it works

GammaBoost+ talks directly to the Windows gamma ramp API — the same OS-level mechanism behind Night Light and your display driver's color settings. No kernel drivers. No process injection. No overlay hooks. No memory access. The app doesn't touch your games at all; it adjusts the gamma table that the operating system hands to your monitor.

That makes it safe with every anti-cheat system in every game. If your monitor's OSD or your GPU driver software can do it, GammaBoost+ can do it — with more control, more presets, hotkeys, and per-app automation.

Built for daily use

• Starts with Windows, sits quietly in the tray, available the second you need it

• Global hotkeys work even when the window is minimized

• Settings sync across machines via Steam Cloud

• Lightweight — runs quietly in the background, no impact on gameplay or stream quality

• Native Windows app — no browser shell required, no account, no telemetry by default

One display, every scenario

Most monitors ship with one gamma curve. Windows gives you one Night Light toggle. GammaBoost+ gives you a full library of presets, sliders for every channel, per-app profiles, and a hotkey for each — so your display adapts to whatever you're doing, instead of the other way around.

Your screen. Your settings. Your call.
