Full brightness, color temperature, and resolution control for external and non-Apple displays. Hardware DDC where it is available, smooth software dimming everywhere else, all from your menu bar.
Free Download 14-day free trial · No credit card · macOS 14+ · Apple SiliconDim or brighten external and non-Apple monitors that macOS normally locks. Hardware DDC control when the panel supports it, seamless software dimming when it does not.
A gamma and overlay dimming layer takes the screen well below the panel's hardware floor for comfortable late-night brightness, without a washed-out backlight glow.
Warm the screen for night, cool it for day. Smooth color temperature on every connected display, set independently per monitor, with Warm, Paper, and Dark-room tints.
Assign any installed ICC color profile per display and switch between them in a click, so each monitor renders color exactly the way you want.
Unlock crisp HiDPI scaling and resolutions your display can do but macOS hides, including retina-style modes on non-Apple panels.
Bind a brightness level or a full preset to an app. Corvus Display applies it automatically the moment that app comes forward.
One click switches brightness, warmth, and color profile together. Ready-made Reading, Movie, Gaming, and Evening presets, plus your own.
Ramp brightness and warmth across the day from your sunrise and sunset, so the screen eases warmer and dimmer into the evening on its own.
Follow the Mac's ambient light sensor, or adapt each display to its own on-screen content so dark and bright scenes stay comfortable.
Stop the display from sleeping during long reads or presentations, optionally only while a chosen app is running.
Send the screen, or the whole Mac, to sleep after a countdown, with lock, restart, and shut down options built in.
Independent control for every monitor, mirroring with an automatic safety net, and a visual arrangement view for multi-display setups.
Toggle and tune the system color features alongside Corvus Display's own warmth and a one-click Dark Mode switch.
Force full RGB range and 8-bit color to correct the dull, grey look some displays show over HDMI and USB-C.
Drive the monitor's own contrast, volume, and input source over DDC, so you can switch inputs and tune the panel without its clunky on-screen buttons.
Blank a display you are not using to save power and distraction, or flood the screen with warm light for a flattering video call.
Everything lives in the menu bar. Use global keyboard shortcuts, scroll on the menu-bar icon, or the brightness keys to drive external displays.
App Intents and a local control API let Shortcuts, scripts, and Stream Deck-style tools set brightness, presets, and more.
Fully localized, with a built-in language picker. Right-to-left support for Arabic and Hebrew.
No account, no telemetry, no tracking. Corvus Display runs entirely on your Mac and talks to nothing.
Brightness, color, resolution and HiDPI, independently for every display.



macOS gives third-party monitors almost no control. Corvus Display brings brightness, color, and resolution adjustment to the displays Apple forgot.
Built from the ground up in SwiftUI and AppKit. A real menu-bar app that feels like part of the system, not a cross-platform port.
No account. No telemetry. No cloud. Your setup never leaves your Mac, and there is no server for us to watch you with.
