MonitorControl v4.0.0

2021-10-26T17:44:44Z

Enhancements

Automatic & manual updates through the app, no more manual downloads 🎉
Moved 'Show advanced settings' under 'Displays'
Added proper support for controlling Apple displays.
Added option to show/hide brightness slider.
Added option to show brightness slider for internal display and apple displays (enabled by default).
Replication of built-in and Apple display brightness to corresponding brightness slider.
Added suffix to similarly named displays for better differentiation.
Option to disable slider snapping for finer control + disable slider snapping by default.
Added option to show slider tick marks for better accuracy.
Added option to use window focus instead of mouse to determine which display to control.
control + command + brightness now controls external displays only (control + Brightness continues to control internal display only)
Added separate tab for menu options.
Added option to restore last saved values upon startup.
Added option for audio device name matching for display volume control selection.
Separated option to change all screens for brightness and volume.
Added option for keyboard fine scale for brightness.
Added option for keyboard fine scale for volume.
Added version check upon startup for mandatory preferences reset upon downgrade or incompatible previous version + notification about this.
Added implementation for command + f1 macOS shortcut to enable/disable mirroring.
Added safer 'Assume last saved settings are valid' option as default instead of startup DDC read (or restore).
Streamlined preference panes, 'Show advanced settings' now affect all tabs. This leads to a better and safer first timer experience (especially because of the influx of many new features).
Added a Quit button to Preferences if menu is hidden (it was not passible to quit the application until this time in this mode only by re-enabling the menu).
Lowered default first-run volume DDC default from 75% to 15% if read is not possible or disabled to prevent unexpectedly loud sound.
Added slider skew setting on a per control basis to have the ability to manipulate DDC slider balance and OSD scale if display control is not linear.
Added the ability to set min. and max. DDC bounds on a per display, per control basis.
Audio device name override option for a display (manually assign a specific audio device to a display).
Advanced setting to invert DDC control range (some displays have the scale reversed).
Advanced setting to remap DDC control code (some displays have contrast and brightness mixed up).
Ability to mark a DDC control as available or unavailable in advanced settings under Displays.
Ability to automatically hide menu icon if there is no slider present in the menu.
Option to show slider percentage for more precision.
Option to set combined or separate OSD scale when combined hardware+software brightness is used.
Apple like smooth brightness change (both for software, hardware, mixed and DisplayServices).
Added support for DisplayLink, AirPlay, Sidecar, screen sharing etc. using window shades (this is an inferior technique to the existing software implementation - gamma control - but still better than nothing). Disabled for any kind of mirroring setups. ¹
Brightness change synchronisation from Built-In and Apple displays to other displays. This makes Touch Bar, Ambient light sensor, Control Center and System Preferences induced changes affect all displays. Synchronisation uses a sophisticated indirect delta method + the user can intervene and adjust individual screen brightness at any time to easily compensate mismatching native brightness levels.
Preferences pane tab selector has a simpler look on Catalina.
All menu sliders are now scrollable using a magic mouse/trackpad swipes or mouse wheel.
Added option for menu to show only items that are relevant to display which shows the menu currently.
Added option to enable combined sliders (note: this option combined with enabled Apple/built-in display syncing and enabled 'change all' keyboard settings finally provides full synchronised control of all displays).
Combined sliders can now display multiple displays when keyboard and brightness syncing is not enabled. ¹
Redesigned sliders to look like Big Sur/Monterey Control Center's sliders. ¹
Quit and Preferences... are now icons for a much cleaner look. ¹
Added option to change additional menu options style or hide them. ¹
Multiple displays are now in nice Big Sur styled blocks - no more ugly separators. ¹
Added customisable gamma/ddc switchover point for combined brightness in the advanced section of Displays.
Added comma separated list for control code override to enable edge cases like controlling Brightness and Contrast at the same time (use VCP list entry 10, 12 for that)
Contrast can now be controlled from keyboard via control + option + command + brightness up/down.
Custom keyboard shortcuts for brightness, contrast, volume and mute
Added Internet Access Policy
Added advanced option to enable zero brightness with software dimming.
Added command + q shortcut in menu when it is in standard text mode.
Rearranged Preferences to fit better on smaller screens in Advanced mode
Alert when repeated interference is detected with applications.
Added 'Avoid gamma table manipulation' option for peaceful coexistence with f.lux.

Other under the hood changes and bug fixes

Standardised internal scale among various displays and DDC ranges for ranged controls.
Uses the new internal scale for combined hardware-software brightness mode.
Improved settings reset functionality for virtual and Apple displays.
Migrated scales to internal float representation to prevent loss of fine detail on transformations.
Fixed double sound when muting multiple external displays at the same time.
Multiple attempts to write last DDC brightness and contrast settings after wake when 'Apply last saved settings' is enabled to make sure that slow displays are handled well
Fixed lack of initial volume configuration if slider is not shown in menu.
Fixed wrong settings being applied to a display when replaced on Apple Silicon (UserDefaults preferences are now tied to specific display strings instead of CGDirectDisplayID - which is no longer semi-unique on arm64).
A lot of refactoring, streamlining and general optimisations.

If you discover issues, make sure to report them in the linked release discussion.
Happy testing 😄
