    Mac Display Optimizer

    Example session with this skill installed

    My external monitor text looks blurry and the brightness buttons on my keyboard don't work for it. Can you fix the scaling and enable brightness control?

    • Read your context and instructions
    • Compiled the mac display optimizer

    I will install Mac Display Optimizer (MDO). It locks your monitor at native 1:1 resolution at the highest available refresh rate, tunes font rendering for sharp text, and enables brightness/color control.

    Status: Checking for Homebrew... Found.
    Action: Running install.command...

    • Installed displayplacer + m1ddc (Homebrew) and pyobjc/rumps (pip)
    • Saved "before MDO" baseline: 3440x1440 @ 60 Hz, fonts=default
    • Locked 3440x1440 @ 100 Hz (HDMI; will auto-select 165 Hz on DisplayPort)
    • Font mode: Sharpest. Pixel format: RGB (no TV mode detected)
    • Loaded daemon + menu bar app (the ◐ icon) — both start at login

    Done. Use the ◐ menu for presets (Day/Evening/Movie/Game), sliders and font modes. "Before MDO" restores everything; "Uninstall" removes all files.

    About this skill

    The problem

    External monitors on Apple Silicon often suffer from blurry text, awkward scaling, or limited refresh rates. Native macOS settings frequently lack hardware brightness and contrast control for non-Apple displays.

    What it does

    • Locks your display at native 1:1 resolution and the highest available refresh rate (up to 165 Hz) — deliberately avoiding blurry virtual-HiDPI downscaling.
    • Four font-rendering modes that fix blurry text on non-Retina and ultrawide panels, including a Reading mode tuned for long texts.
    • Hardware DDC/CI brightness, contrast and RGB color control directly from the Mac, with automatic software-gamma fallback over HDMI on M1/base-M2.
    • Display presets for Day, Evening, Movie (film-tuned for VA ultrawides) and Game, plus an automatic Day/Evening scheduler.
    • Detects and warns about signal issues like YCbCr color encoding (blurry, color-fringed text) and Night Shift conflicts.
    • Menu bar app with live sliders + background daemon. "Before MDO" restores your screen exactly as it was before installation, and a one-click uninstaller removes every file.

    Frameworks & tools

    macOS 13+, Apple Silicon, Homebrew, Python, displayplacer, m1ddc.

    Why this beats prompting it yourself

    Manually configuring font smoothing, DDC tools and resolution wrappers means juggling multiple CLI utilities and LaunchAgents. MDO handles installation, login persistence and control in one audited package — with a full security disclosure (references/output-contract.md) documenting every file it creates, modifies and removes. No network access at runtime, no telemetry, never executes remote scripts.

    Requires Homebrew pre-installed (never auto-installed). Best suited for Apple Silicon Macs on macOS 13+. Hardware DDC brightness is unavailable on the built-in HDMI port of M1/base-M2 Macs (Apple hardware limitation) — MDO falls back to software gamma dimming there; DisplayPort/USB-C enables full hardware control. Intel Macs: everything works except hardware DDC. Font-mode changes require restarting apps to be visible. Controls external displays only — a MacBook's built-in screen is intentionally left to macOS.

    Terminal/Shell runs the installer and the Python engine (displayplacer, m1ddc, defaults). File read/write stores settings in ~/.mac_display_optimizer and installs the app to ~/MacDisplayOptimizer plus two LaunchAgent plists for login persistence. Network Access is used ONLY during installation, when Homebrew/pip download the declared dependencies (github.com, pypi.org) — the program itself makes no network requests at runtime, collects no data, and never executes remote scripts. Browser access is not used. A full file-footprint disclosure ships in references/output-contract.md.

    Frequently Asked Questions

    This skill is specifically designed for Apple Silicon (M1, M2, M3 series) Macs running macOS 13 or later. It addresses common display issues unique to the Apple Silicon architecture, such as blurry font rendering and limited hardware control for third-party monitors.

    Unlike standard macOS settings, this skill utilizes DDC/CI protocols to control your monitor's actual hardware brightness and contrast. It also provides low-level font rendering adjustments and native 1:1 resolution locking that bypasses the blurry downscaling often seen in virtual-HiDPI modes.

    The package includes the full AI agent skill, a pre-configured menu bar app for live controls, and a detailed security disclosure. You also receive a one-click uninstaller to ensure a clean removal if you ever choose to revert your settings.

    The setup process uses Homebrew to install necessary helper utilities like displayplacer and m1ddc. The skill then configures these tools automatically, handling all CLI commands and background persistence so you don't have to manage them manually.

    Yes, it includes a smart automatic scheduler that adjusts brightness, contrast, and color presets based on the time of day. It also features a built-in monitor to detect and resolve common signal issues like YCbCr color encoding conflicts.

    This skill does not require network access at runtime and contains no telemetry. All configuration stays local to your machine, and the included 'output-contract' documents every file the skill creates or modifies for full transparency.
