A new GammaBoost+ Rebuilt around presets: a new design from the ground up, with a sidebar for Presets, Manual, Eye Care, Community, My Presets, Profiles, OBS Studio and Stream Deck. Light or dark: a new light look made of glass, tinted by the preset that's on,…
New in Manual Exposure: more or less light, like a camera. Unlike Brightness, white stays white. Shadows and Highlights: the dark and bright ends on their own, on NVIDIA's −100 to 100 scale, so values from an NVIDIA filter copy straight over. Tint Color and Ti…
Fixes Your Default profile turns on at launch: GammaBoost+ now opens in your profile with its ★ preset on screen, as the profile's "★ turns on when you switch to this profile" setting says. Before, it opened on the last preset you used, even one from another p…
What's new HDR: presets now look right with Windows HDR on (NVIDIA), Manual and the display menu show when a display is in HDR. Your preset stays on: if Windows or a game resets your screen's colors (sleep, display changes, some fullscreen games), it comes bac…
Clear the fog New: Black Point (Manual → Light). A high gamma lifts dark areas but lays a grey haze over them; Black Point pulls that haze back to black without blowing out the bright parts. It's the opposite of Black Level, which lifts the darkest shades. Con…

A preset for each monitor Pick a monitor, then a preset: only that monitor changes. All displays still sets every monitor. The picker shows each monitor's preset. The on/off switch and key act on the picked monitor. With All displays picked, they act on all of…
UI rework A new design: graphite colors, squared menus and dialogs, cleaner preset and Community art. Read before you turn on: clicking a preset card shows it without turning it on. Turn it on from the banner, or double-click the card. A small on/off switch in…
GammaBoost+ just surpassed 1,000 users, and I honestly can't thank you all enough... When I started building GB+, it was simply the tool I wanted for myself and friends: a way to see clearly in dark games and make games more vibrant with ease and without washi…
