GammaBoost+ is a gamma and display control app for Windows. It adjusts your monitor's gamma, brightness, contrast, saturation, and color temperature in real time, so dark games become readable, washed-out colors come back to life, and you can spot enemies hiding in shadows.
Use it as a faster, more powerful alternative to NVIDIA Control Panel, AMD Adrenalin color settings, and Windows Night light — with presets, per-game profiles, and a hotkey for everything.
•Games that are too dark to see in
•Washed-out or faded colors
•Lost shadow detail in shooters and horror games
•Low digital vibrance and dull saturation
•Eye strain from a bright, blue screen at night
•A stream that looks darker than your screen
•One-click optimized presets — High Contrast, Warm Boost, Cool Boost, Vivid, Forest Ops, and Color Boost.
•Gamma and brightness control — Gamma, brightness, contrast, black point, black level, highlights, vibrance, tint, and color temperature (1000K–10000K).
•Per-channel RGB and tone curve — Adjust red, green, and blue separately, or draw a custom curve.
•Digital vibrance and saturation — Controls NVIDIA Digital Vibrance and AMD Saturation directly. No FPS cost.
•LUT import — Turn any .cube LUT from DaVinci Resolve or Adobe into a screen preset, with a match score. Uses the GPU's color matrix on NVIDIA.
•LUT export — Export any preset as a .cube LUT for OBS, Streamlabs, or your video editor.
•Per-game profiles — Switch on automatically when a game launches and back when it closes.
•Hotkeys and mouse buttons — Bind any preset to a key or mouse button. Works while you play.
•Community presets — Browse, try on your own screen, save, and share.
•Eye-care suite — Night Mode, Soft White, and Screen Dim — a blue light filter and screen dimmer that stacks on any preset.
•OBS sync — Your stream shows exactly what you see.
•Stream Deck plugin — Presets, profiles, and live slider control on keys and dials. Free.
•Multi-monitor and HDR — One display or all of them. Windows HDR supported on NVIDIA.
•Unlock full range — Push past the Windows gamma limits for stronger adjustments.
•Works with every game — Changes the display's gamma at the Windows level, so it works with any game, app, or video.
•Never touches your games — No overlay, no injection, no memory access, and no FPS cost.
•GPU support — Gamma and color work on any GPU. Digital vibrance needs NVIDIA or AMD; HDR and the LUT color matrix need NVIDIA.
•Always on — Starts with Windows, re-applies after sleep or display changes, and syncs profiles through Steam Cloud.
•10 languages — English, French, German, Spanish, Portuguese, Russian, Turkish, Japanese, Korean, and Simplified Chinese.
