v1.0.0
13f0f08

First public release.

What it does — digital vibrance, gamma, contrast and brightness as named profiles you
switch with a hotkey, without leaving a game. Vibrance goes through NVIDIA's NVAPI; gamma,
contrast and brightness go through the GDI gamma ramp and work on any GPU.

Highlights

  • Per-monitor overrides inside a single profile, matched by vendor, position, index or
    EDID rather than the adapter names Windows renumbers
  • Settings window with live preview, a real transfer-curve graph drawn from the lookup
    table that actually reaches the driver, and a vibrance colour preview
  • A watchdog that reapplies your profile when a fullscreen game takes the gamma ramp, or
    the driver resets vibrance on a display-mode switch
  • Defaults are Ctrl+Shift+…: Windows reports AltGr as Ctrl+Alt, so Ctrl+Alt bindings
    fire while typing on Spanish, German and most non-US layouts. If you do bind Ctrl+Alt,
    AltGr presses are detected and ignored
  • Per-user install, no admin prompt. --uninstall removes every registry entry it made

Install — run the setup exe, or winget install NachoSC.ScreenTuner, or unzip the
portable build anywhere.

Note on SmartScreen — the binary is not code-signed, so Windows will warn on first
run. Click More info → Run anyway. The source is here and build.bat reproduces it.

Requires Windows 10/11 64-bit. Vibrance needs an NVIDIA GPU; everything else works on
AMD and Intel. AMD saturation via ADL is on the roadmap — testers welcome.
