Ability to easily create and switch display layout protection presets

[waydabber]

MacOS stores the last saved layout for a given combination of active displays. This is great but sometimes it is annoying. Would not it be great to be able to save a specific display layout (display location, main/extended status for displays and mirroring) configuration and restore it as needed?

The function should be intelligent - if one or more of the displays are missing or not connected, the function still could restore the settings and adapt to the missing displays.

Also, layouts could be set as preferred - so if a new display is connected or there is some change or during app startup BetterDummy would restore the preferred configuration - connecting a new display would not totally mess up the desktop layout anymore.

+1 for this, would be great to have this included in BetterDummy. My displays change the window layout nearly every time the external one sleeps, I currently cope with that by using the window manager Moom, which can save individual layouts and have them restored with a keyboard shortcut.

This is definitely a priority on the todo list. My plan is to have the ability save these data as a profile to be recalled:

• Enabled dummies
• Mirroring configuration
• Resolutions/refresh rate
• HDR status
• Location of displays in the display configuration
• Main display status
• Orientation of the display

I'd like to make the various configurations available in a menu for quick access and also hotkey assignable. I'd also like to give the ability to self-recover if one or more displays are unavailable. Also there would be a hotkey to update the savedata for a configuration.

[waydabber]

Presets could be invoked via menu, hotkey or tied to applications and application window state (full screen or not). See this discussion: https://github.com/waydabber/BetterDisplay/discussions/817#discussioncomment-3331646

I would love this feature. I'm trying out this application with a mix of my laptop, a TV, and a monitor, and while the configuration ability is amazing, my presets for arrangement, resolution, etc. are consistently forgotten. Given how much time it can take to dial these in, a way to quickly recover would be much appreciated and convert me into a paying customer!

[waydabber]

Yes, still on it, will get there eventually! :)

Hey, just wanted to say thank you for such a great tool, and that M1 users could really use that feature especially when displaylist is not working anymore :)

Having your monitors layout messed up after sleep/restart/disconnect and need to arrange them manually every time is extremely annoying :(

[waydabber]

Right, this is continuously on my todo list but I am getting tangled up with all the other stuff that needs to be done. Will get there. But will not put a milestone on it anymore unless I actually I know I can finish it properly. :) The same with syncing which is an other major feature I want to do right.

Will this also impact arrangements of multimonitor. Sometimes when the monitor with better display is connected, it moves the laptop display around @waydabber

+1

[waydabber]

Yes, the goal should be to restore multi-monitor arrangements if for some reason displays are mixed up.

@waydabber do you know any workaround to automate switching the source of a mirror from one display to another?

[waydabber]

Yes, but it involves coding so that might not be very useful. When I finally add CLI support it should have commands eventually to manage mirroring.

[matkoch]

"coding" is fine :) can you give some more hints on that?

[waydabber]

Sure, take a look at https://developer.apple.com/documentation/coregraphics/1454531-cgconfiguredisplaymirrorofdispla and other associated functions. You can find a lot of code examples out there I think utilizing these.
