Aggressive disconnect - option to auto-disconnect a display upon detection (or restore disconnect state upon app startup)

Discussed in #1845

Hi, I have BetterDisplay Pro and I was hoping it could be configured to remember a display as disabled at startup. I have unchecked "Auto-connect all displays on startup" but it doesn't seem to have an effect... MacOS (Ventura) insists on reconnecting all displays every time. For now all I can do is set the unwanted display to mirror mode, but I'd rather be able to permanently disable it. Maybe this seems like a weird request but I only want to use this displayport output when I dual boot into Linux.

Thanks!

For this an option would be needed to auto-disable a display on initial detection.

Fully agree on that one, I use a dual monitor setup and I've plugged both in a way I can use Mac and PC on one or extend the other when I don't need one of them. But each time the Mac goes into sleep, when it wakes up, it re-enables by default both monitor, which is not what I'd like to see. Many thanks in advance !
PS : I've never found any software being able to do so, and I'll obviously pay for a pro license if this would be implemented.

@sgrienen - for turning off a connecting display on wake you can try this:

Hey, thanks for answering so quickly @waydabber ! It seems to be working, I'll continue testing in the coming days, but it does really look promising ! Thanks again ! Le jeu. 7 sept. 2023 à 19:57, waydabber ***@***.***> a écrit :

I'll add a per display option to keep a display disconnected (disconnect instantly upon detecting it) until the user manually connects it. This should also solve issues for displays that seem to connect/disconnect multiple times during wake breaking the "disconnect reconnected displays upon wake" option.

Fantastic ! Now the next challenge for me is to find an option allowing me to switch automatically to the right input when I disconnect my PC from the USB-C, so when I enable the secondary display on the Mac using BetterDisplay, it switches to DisplayPort. I thought the screen would be clever enough to do that automatically when no source can be found anymore, but it seems it doesn't... Is there any option via DDC I could use for that ? Many many thanks ! Le ven. 8 sept. 2023 à 16:33, waydabber ***@***.***> a écrit :

Changed how this works a bit - the new "Aggressive disconnect" feature should enforce the existing disconnect feature.

@sgrienen - not that I know of. You can try assigning a keyboard shortcut to DDC inputs and see if it works. I plan to add DDC control features to macOS Shortcuts later - with that you could incorporate commands to any custom workflow you create.
