Simple console tool for saving and restoring display arrangement on OS X.
For doing it, the tool uses serial numbers of the displays and not the IDs that OS X assigns to them.
da help - prints help text
da list - prints a list of all connected screens and their current setup
da save <path_to_plist> - saves current display arrangement to file
da load <path_to_plist> - loads display arrangement from file
If <path_to_plist> is not specified - the default is used: '~/Desktop/ScreenArrangement.plist'
This fixes Y-axis arrangement and includes some work to ensure non-edid displays work, too
Now includes memorizing and restoring the mirror flag.
Includes code to tie displays to their port so a setup with identical displays that don't have a serial number in EDID data will be recognized by their physical connection. Be aware that unplugged displays have to be connected to the exact same port again to be recognized.
Currently there are no problems. See previous issues below
[solved this one 19.0.3.2019]
- I've experienced lately that display manufacturers leave the serial number section in EDID
- data untouched (e.g zero) and thus if you happen to have two identical displays you end up
- not being able to determine which one goes where.
- Adding to that is the fact, that Apple macOS separates the display info from the port it
- is plugged into. I know why they do it but it sucks in this case.
[removed this bad idea in favor of other solution 19.03.2019]
- I have found out for some displays you can identify different audio latency values
- comparing HDMI 1 to HDMI 2 on the display. So you can differentiate two displays by using
- different HDMI IN ... probably not a solid solution but it helped me in a situation and
- i've included this in my build.
