Settings & Hotkeys

OLED Guard Pro is built around a small set of presets that cover the common cases, with knobs underneath for anyone who wants to tune further.

Built-in presets

Six factory presets ship with the app. Every one of them has Auto Mode on, the Morphological noise-gap filter, and the High quality preset by default.

| Preset | Tuned for | | ------------------------------- | --------------------------------------------------------------- | | Gaming — Fast | Multiplayer / esports — short accumulation, low dim cap | | Gaming — Slow | Cinematic single-player — longer accumulation, higher dim cap | | Media | Video, streaming, letterboxed film — stays out of the way | | Work / Browsing / Coding | Productivity — fast decay, protects only strongly static UI | | Creative / Design | Photoshop / Figma / Premiere — protects palettes, tolerates viewport motion | | Dashboard / Monitoring | Grafana, trading terminals — strong protection, stays readable |

You can also save your own preset from the Overlay page. Custom presets are stored as JSON in %LOCALAPPDATA%\OLEDGuard\ and can be exported/imported.

Protection knobs

Available on the Overlay page (basic) and Advanced page (full set):

  • Intensity (1–5) — overall response scale. Most users only ever touch this slider.
  • Max dim amount — the ceiling on how dark the overlay can go.
  • Stability floor — risk floor for pixels that have been static for a long time, regardless of luma.
  • Dynamism gate — how much per-pixel motion is required before a pixel counts as static.
  • Accumulation / decay time constants — how fast risk builds up and recovers.
  • Luma floor — minimum brightness for a pixel to count toward risk accumulation.

Overlay settings

  • Mode — Noise (default), Static Dim, Pixel Shift, or Ordered Dither
  • Noise gap filter — Off / Smooth / Neighborhood / Morphological (default). See Protection Modes
  • Noise speed / scale — animation rate and feature size of the noise pattern
  • Vignette — independent edge weighting per side (left / top / right / bottom) layered on top of the chosen mode

Overlay colour

Seven dark tints to choose from on the Overlay page:

  • Black — pure dimming, no subpixel wear
  • Dark Gray — softer contrast than black
  • Dark Blue — exercises short-lived blue subpixels
  • Dark Red — night-vision safe
  • Dark Amber — warm, blue-light free
  • Dark Green — highest lumens per photon
  • Dark Teal — balanced blue-green

Quality presets

Quality controls capture and render rate plus the analysis resolution. Higher = more accurate detection at higher GPU cost.

| Preset | Capture FPS | Render FPS | Analysis short-edge | Use case | | ----------- | ----------: | ---------: | ------------------: | ------------------------------------- | | Low | 2 | 4 | 144 px | Older GPUs, low-power machines | | Medium | 4 | 8 | 270 px | Balanced default | | High | 8 | 16 | 540 px | Recommended for most modern systems | | Ultra | 8 | 16 | 720 px | Maximum fidelity on capable GPUs |

All factory presets ship at High.

Hotkeys

Six global hotkeys, all defaulting to Ctrl+Shift+... combos and all individually rebindable from the Hotkeys page:

| Hotkey | Action | | ----------------- | ----------------------------------------- | | Ctrl+Shift+O | Toggle protection on/off | | Ctrl+Shift+V | Toggle vignette edge protection | | Ctrl+Shift+H | Toggle the heatmap visualisation | | Ctrl+Shift+− | Intensity down | | Ctrl+Shift+= | Intensity up | | Ctrl+Shift+G | Show / hide the in-game tuning HUD |

System integration

  • Start with Windows — runs OLED Guard at login via the Windows Run key. On by default for new installs.
  • Start minimised to tray — when on, the app skips the dashboard window on launch and lives in the tray. On by default. The first-run welcome overlay overrides this for the very first launch.
  • Window placement — the dashboard window remembers its size, position, and maximised state across launches. Restore is validated against the current monitor layout, so an unplugged display doesn't strand the window off-screen.
  • Single-instance — launching a second copy raises the existing window instead of spawning a duplicate engine. Safe to leave the auto-start enabled even if you sometimes double-click the tray icon.
  • System tray menu — Start/Stop Protection, Open OLED Guard Pro, Quit.
  • Closing the window minimises to tray with a one-time balloon notification. Quit from the tray menu actually exits.
  • Away Mode — after a configurable idle period (default 10 min), switches to a uniform low-dim hold until you come back. Off by default; toggle on the Settings page.
