    Problem

    Monitors are stuck in the dark ages.

    It's 11pm and your screen is blinding. The buttons under your monitor are tiny. You shouldn't need a manual to look at your own screens comfortably.

    One screen is blinding at night.

    Brightness 92%

    11:03 PM, still glowing.

    Your Mac keyboard has brightness keys. Your external monitor acts like it never heard of them.

    The controls are hidden on the back.

    Five tiny buttons. No labels. One wrong press opens the wrong monitor menu.

    Each display has its own brightness.

    MacBook Pro78%
    Dell UltraSharp42%
    LG UltraFine63%

    You end up matching brightness by eye, one monitor at a time.

    One menu bar. Every display. Every moment of your day.

    We built DisplayBuddy because we got tired of it too. Your displays should feel like part of your Mac, not three different machines you have to wrangle separately.

    Real control

    Real brightness. Real volume. No more reaching behind your monitor.

    DisplayBuddy talks directly to your monitor over DDC. That means real hardware brightness control, not just dimming. Your eyes will know the difference.

    Sync

    Move one slider. Every display follows.

    Sync mode locks your displays together so when you dim one, you dim them all. No more matching brightness between a 27" and a 32" by eye.

    Schedules

    Set it once. Your displays follow your day.

    Tie any preset to sunrise, sunset, a time of day, your charger, or a connected display. Soft and warm in the morning. Crisp and bright while you work. Calm on your eyes after dinner. DisplayBuddy handles it before you reach for a button.

    Tested extensively

    Every display. Even the ones that don't want to cooperate.

    Most monitors respond to DDC commands over the cable. If a display refuses, DisplayBuddy switches to gamma control automatically. And for smart monitors from LG webOS and Samsung Tizen, DisplayBuddy reaches them over Wi-Fi. One app. Every screen on your desk.

    DDC

    The universal way most monitors talk. DisplayBuddy speaks it fluently: Dell, Acer, BenQ, HP, ASUS, Xiaomi, and more.

    Gamma fallback

    When a monitor refuses DDC, DisplayBuddy dims through gamma control automatically. No setup, no thinking.

    Wi-Fi for smart monitors

    Direct control for LG webOS and Samsung Tizen displays that ignore DDC. The only Mac app that does this properly.

    Two ways tomorrow morning can go.

    Without DisplayBuddy
    • Squinting at a too-bright screen at 11pm.
    • Fumbling for tiny buttons on the back of your monitor.
    • One display at 80%, the other at 40%, all day.
    • A smart monitor that refuses to listen to your Mac.
    • A setup that fights you instead of fits you.
    With DisplayBuddy
    • A warm, soft screen the moment the sun goes down.
    • One slider that moves every display together.
    • Your Work, Movies, and Gaming setups one click away.
    • Smart monitors that finally behave.
    • Displays that fit your life, not the other way around.

    If you're tired of fighting your monitors, DisplayBuddy is the right choice.
