ScreenTuner 1.1.0

ScreenTuner can now tell you when there is a new version, and install it for you.

This is the last update you will have to install by hand. Versions before this one have no
way of knowing a release exists, so 1.0.x will not notify you about 1.1.0 — from here on
it will.

How it works

• Once a day, ScreenTuner asks GitHub whether there is a newer release.
• If there is, you get a tray notification. Click it, or the new Update to x.y.z…
  entry in the tray menu, and it asks whether to install.
• Say yes and it downloads the official installer, checks its SHA-256 against the digest
  GitHub reports for that exact file, runs it silently, and reopens. Your profiles and
  settings are kept.

Nothing interrupts you. No dialog ever appears on its own — this is an app you leave
running inside a game, so the notification is the only unprompted thing, and it goes away
by itself. Every dialog is reached from a click.

Turning it off — Settings → Options → "Check GitHub for new versions", or
"check_for_updates": false in profiles.json. The check is an unauthenticated GET to
the public releases API: nothing about you or your machine is sent, and the app still has
no telemetry of any kind.

A portable copy cannot replace itself while it is running, so it opens the download
page instead.

Also fixed

• Running from a source checkout looked for profiles.json and icon.ico in the wrong
  place after the sources moved into src/. Installed and portable copies were never
  affected.

Upgrading — run the setup exe over your existing install, or
winget upgrade NachoSC.ScreenTuner. Settings and profiles are preserved.

Note on SmartScreen — the binary is not code-signed, so Windows will warn on first
run. Click More info → Run anyway. Verifying the download proves it arrived intact, not
that the release is trustworthy; that needs code signing, which is on the roadmap.

Requires Windows 10/11 64-bit. Vibrance needs an NVIDIA GPU; gamma, contrast and
brightness work on any GPU. AMD and Intel saturation is the next roadmap item — testers
welcome.

ScreenTuner 1.0.1

A small bug fix, plus a test suite. Nothing you have configured changes — upgrading is
safe, and your profiles.json is untouched.

Fixed

• A hotkey consisting only of whitespace — "hotkey": " " in a hand-edited
  profiles.json — was parsed as the + key and registered globally, so pressing +
  anywhere switched profiles. It is now rejected like any other empty value.

Added, for contributors

• A test suite under tests/, split by what a machine can answer rather than by test
  size. tests/unit/ needs nothing but Windows — no GPU, no build, no install — and
  covers the gamma ramp maths, hotkey parsing, monitor matching, profile resolution,
  config loading, and the privacy scrubbing on --diagnostics. tests/system/ holds the
  hardware tests that need real displays and, for vibrance, an NVIDIA card.
• This matters for the AMD and Intel work on the roadmap: someone without an NVIDIA card
  can now run tests\run.bat unit and check they have not broken anything, which was
  previously impossible.

Upgrading — run the new setup exe over your existing install, or
winget upgrade NachoSC.ScreenTuner. Settings and profiles are preserved.

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; gamma, contrast and
brightness work on any GPU. AMD saturation via ADL is on the roadmap — testers welcome.

ScreenTuner 1.0.0

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.
