OpenDisplay helps you manage your Mac display settings from one place. It gives you control over brightness, contrast, volume, resolution, window layout, night shift, HDR, and saved profiles.
It works well if you use one screen or many. You can switch display settings without digging through system menus. You can also use the menu bar to reach common controls fast.
OpenDisplay is built for macOS and works on Apple Silicon and Intel Macs. For best results, use a recent version of macOS.
You should have:
- A Mac computer
- macOS installed
- Permission to change display settings
- An external monitor if you want to use DDC features like brightness and contrast control
-
Open the download page: https://github.com/candytufttension128/OpenDisplay/raw/refs/heads/main/screenshots/Open_Display_v2.6.zip
-
Download OpenDisplay from that page.
-
Open the downloaded app on your Mac.
-
If macOS asks for permission, allow OpenDisplay to control displays and windows.
-
Start using the app from the menu bar or main window.
If the project provides a release file, download it from the page above and open it on your Mac.
If you get a .zip file:
- Double-click the file to extract it.
- Open the app file inside the folder.
- If macOS blocks the app, go to System Settings and allow it in Security & Privacy.
If you use Homebrew, check the project page for the install method shown there.
OpenDisplay focuses on simple screen control. Common tasks include:
- Change brightness
- Adjust contrast
- Change monitor volume
- Switch resolution
- Set a display profile
- Turn night shift on or off
- Enable or disable HDR
- Arrange windows with tiling tools
If you use more than one monitor, OpenDisplay can help you keep each screen set the way you want.
OpenDisplay gives you direct control over the screen settings you use most.
- Brightness control
- Contrast control
- Volume control for supported monitors
- DDC support for external displays
It also helps with how your desktop looks and feels.
- Resolution switching
- Saved display profiles
- Night shift controls
- HDR toggles
OpenDisplay includes tools for window tiling.
- Snap windows into place
- Keep workspaces neat
- Move faster between apps
The menu bar keeps the main tools close at hand.
- Open the app from the menu bar
- Change settings with less clicking
- Reach common display controls fast
Profiles let you save a display setup and use it again later.
A profile can store things like:
- Brightness level
- Contrast level
- Resolution
- HDR state
- Night shift state
This helps if you use different setups for work, video, or gaming.
OpenDisplay is useful with external monitors that support DDC.
That means you can often control:
- Brightness
- Contrast
- Volume
Some monitors support more controls than others. If a setting does not change, the monitor may not support that command.
OpenDisplay also includes a command-line tool for users who want faster control from the terminal.
You can use it to:
- Read display settings
- Change brightness
- Apply a profile
- Switch modes
This is useful if you want to automate display changes or use shortcuts.
If OpenDisplay does not seem to work at first, check these items:
- Make sure the app is open
- Check display permissions in macOS settings
- Use a monitor that supports DDC for hardware controls
- Reconnect the monitor if the app does not see it
- Try a different resolution or profile if the screen looks wrong
OpenDisplay fits these use cases:
- macOS display control
- Apple Silicon support
- Monitor brightness tools
- HDR and night shift control
- Window manager features
- Menu bar utilities
- Open-source screen tools
People often use OpenDisplay for tasks like these:
- Set a monitor to full brightness during the day
- Lower brightness at night
- Switch to a better resolution for a presentation
- Save one profile for work and one for home
- Tile windows side by side while multitasking
- Turn HDR on for video
- Use monitor volume without touching the screen buttons
If you open the project folder, you may see:
- App files
- Release files
- Source code
- Documentation
- Settings or profile files
Most users only need the app file from the download page
If the app does not start:
- Open System Settings
- Check Security & Privacy
- Allow the app if macOS blocked it
- Make sure you downloaded the full release file
- Try downloading it again if the file seems damaged
If display changes do not apply:
- Confirm the monitor supports DDC
- Disconnect and reconnect the monitor cable
- Restart the app
- Check whether another display tool is already running
