Mac display presets for external monitors: work, night, and presentation modes
If your docked Mac desk changes during the day, stop readjusting every monitor by hand. Save the boring states once and switch between them.
Use display presets when you repeatedly change the same external monitor settings: brightness for day and night, input source for another machine, volume on a monitor with speakers, or resolution for a presentation. If the job is a live demo or classroom handoff, run the Mac presentation display settings checklist first. Do not make presets for settings you almost never touch.
TeenyDisplay saves named presets for connected displays. Its source captures brightness, contrast, volume, input source, resolution, refresh rate, and HiDPI state when those values are available, then restores the matching displays later.
Quick preset plan
| Preset | What to save | Why it helps |
|---|---|---|
| Work | Normal brightness, primary input, standard resolution and refresh rate. | One click gets the desk back after gaming, screen sharing, or another computer. |
| Night | Lower brightness, lower contrast if supported, synced brightness across displays. | You avoid chasing three sliders every evening. |
| Presentation | Conference-room input, safe brightness, stable resolution. | Less fumbling before a call or meeting. |
| Focus | Dim side displays or park the secondary display on another input. | The setup pushes attention toward one screen. |
What macOS gives you by default
Apple's Displays settings cover the foundation: display arrangement, mirror or extend, resolution, brightness where available, color profile, rotation, refresh rate, Night Shift, and display detection. That is enough for many desks.
The gap appears when a third-party monitor exposes controls through its own hardware menu instead of macOS. You can arrange the screen in System Settings but still have to reach for physical buttons to change brightness, contrast, volume, or input.
Display presets are for that gap. They are not a replacement for basic Mac display setup. They sit on top of it.
What TeenyDisplay saves
TeenyDisplay's preset code reads the current display list and creates one saved entry per display. Each entry uses a stable display key from vendor ID, product ID, and serial number when available, so a preset can find the same monitor again instead of relying on a temporary display ID.
The saved values are practical: brightness, contrast, volume, input source, resolution width and height, refresh rate, and whether the selected mode is HiDPI. If a display does not support a feature, that value is not saved for that display.
When you apply a preset, TeenyDisplay matches the saved entries to currently connected displays. Disconnected displays are skipped. Connected displays get their saved values back through DDC where possible, CoreAudio for supported display audio, software dimming when DDC brightness is unavailable, and CoreGraphics for display modes.
Brightness sync belongs with presets
Presets solve the big jumps. Brightness sync solves the small drift between them.
The TeenyDisplay brightness-sync source supports two modes: sync all external displays, or sync only selected displays. When one linked display changes by a delta, the linked displays move by the same delta and clamp between 0 and 100 percent.
That means your Night preset can get the desk into the right range, then one manual adjustment can move the whole external setup together. If one monitor is brighter by nature, use selected linking or leave it out. For the keyboard layer, read Mac external monitor keyboard shortcuts.
How to create useful presets
- Set the desk exactly how you want it: brightness, contrast, input, volume, resolution, and refresh rate.
- Open teenydisplay from the menu bar.
- Save a named preset such as Work, Night, Presentation, or Focus.
- Repeat only for states you actually use.
- Optional: set a default preset if you want TeenyDisplay to apply it on launch.
- Optional: use
teenydisplay://preset?name=Workfrom Shortcuts, Alfred, or another launcher that can open URLs.
Keep the names plain. Clever preset names are fun once and annoying forever.
When presets are the wrong tool
Skip presets if you only use one monitor at one brightness level. A preset will not make the setup better. It will just add another thing to manage.
Skip presets while diagnosing color. If an external monitor looks washed out, use the Mac external monitor color profile checklist before saving a Work or Night state.
Use a heavier display app if you need virtual displays, EDID overrides, custom scaling experiments, picture-in-picture, or full display layout protection. TeenyDisplay is intentionally narrower. It can switch available resolutions and refresh rates, but it is not trying to be a display engineering suite.
Use the monitor's own menu when a setting is vendor-specific and not exposed over DDC. Some monitors accept brightness but ignore input switching, or support input switching but not volume. Presets can only restore controls the display exposes.
Common questions
Can macOS save external monitor brightness presets?
macOS can manage display arrangement, resolution, brightness where available, color profile, and refresh rate in Displays settings. TeenyDisplay adds named presets for external monitor controls such as brightness, contrast, volume, input source, resolution, refresh rate, and HiDPI state.
What should I save in a display preset?
Save settings you actually change: brightness, contrast, input source, volume, and sometimes resolution or refresh rate. Tie the preset names to real contexts such as Work, Night, Presentation, or Focus.
Do presets work if a monitor is disconnected?
TeenyDisplay skips saved preset entries for displays that are not currently connected.
