GammaBoost+

Description

Make your games brighter and more vibrant

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.

What it fixes

• 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

• A soft, blurry picture

• Colors that are hard to tell apart with colorblindness

Features

• One-click optimized presets — High Contrast, Warm Boost, Cool Boost, Vivid, Forest Ops, and Color Boost.

• Gamma and brightness control — Gamma, exposure, brightness, contrast, black point, shadows, 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.

• NVIDIA-style filters, in every game — Exposure, Shadows, Highlights, Sharpen, Black & White, and Colorblind, on NVIDIA's −100 to 100 scale, so values from an NVIDIA filter copy straight over. Unlike NVIDIA's game filters, they work in every game.

• 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. Sharpen uses your monitor's own sharpness setting (most monitors have one). Colorblind and Black & White's filter colors need NVIDIA with HDR off.

• Always on — Starts with Windows, re-applies after sleep or display changes, and syncs profiles through Steam Cloud.

• 17 languages — English, French, German, Spanish, Portuguese, Russian, Turkish, Japanese, Korean, Simplified Chinese, Polish, Italian, Ukrainian, Traditional Chinese, Thai, Vietnamese, and Indonesian.
