Most display utilities stop at the slider. These pages cover the parts of Candela that keep a record of your display and act on it, the temporary controls that put things back on their own, and the escape hatches for hardware that misbehaves.
- OLED care. Enrolling a display, the dimming settings, the exposure heat map, panel hours, and what the permission-free path can and cannot see.
- Checkup. The panel diagnostic: what it measures, how each claim is graded, the planted control that grades your own eyes, and what the report does not certify.
- Everyday controls. Changes that end themselves: keeping a display awake until a set time, pausing OLED dimming without unenrolling, and an optional HDR shortcut.
- Resolutions. The size list, the HiDPI sizes macOS does not list, the in-between sizes Candela renders, and what happens when a size fails.
- Arrangement. Moving display tiles, choosing the main display, confirming changes, and finding saved-setup controls.
- Saved display setups. Remembering rotations and positions, what happens on reconnect, and when a saved setup cannot be restored.
- Virtual Displays. Creating another desktop, changing its size, recreating it at launch, and removing it.
- Diagnostics. What the per-display Diagnostics page reports and how to export it for an issue.
- Advanced settings. The knobs that are set with
defaults writeinstead of a control, and why they are there.
Everything below is in Candela's Settings window (Command-comma, or Settings from the menu bar item). The sidebar runs top to bottom: General on its own, then Care (Health, Protection, OLED Care, Checkup), then Controls (Menu Bar, Keyboard, Arrangement, Virtual Displays), then About, and each connected display has its own entry below those.
Nothing you record. Exposure history, panel hours and checkup reports are files on your own disk, and the only way any of them travels is you exporting one deliberately. The app makes one network request of its own accord: the signed update check.
