Get "error finalizing display configurations" error

[fluffy-critter]

I'm running macOS 11.2 on an M1 Mac mini with an LG 4K HDR monitor, and whether I run the homebrew release or build from source, most commands I run give me an error without applying any changes. For example, if I use the configuration restoring command from displayplacer list, this happens:

bucket:~ $ displayplacer "id:98AD201D-167F-2937-3D19-FC1626C9B248 res:2560x1440 hz:60 color_depth:8 scaling:on origin:(0,0) degree:0" "id:1D8AB08D-7B12-48C9-0857-D6964E3302DB res:1920x1080 hz:60 color_depth:8 scaling:off origin:(2560,-60) degree:0"

Error finalizing display configurations

If I set just the resolution, it works fine, though; these commands work without error:

bucket:~ $ displayplacer "id:98AD201D-167F-2937-3D19-FC1626C9B248 res:3840x2160" 
bucket:~ $ displayplacer "id:98AD201D-167F-2937-3D19-FC1626C9B248 res:2560x1440"

If I add color_depth back in, the error comes back:

bucket:~ $ displayplacer "id:98AD201D-167F-2937-3D19-FC1626C9B248 res:2560x1440 color_depth:8"
Error finalizing display configurations

Specifying resolutions by mode number works as well:

bucket:~ $ displayplacer "id:98AD201D-167F-2937-3D19-FC1626C9B248 mode:155"                   
bucket:~ $ displayplacer "id:98AD201D-167F-2937-3D19-FC1626C9B248 mode:130"

Since I'm on an HDR monitor I suspect there's something wrong with how it's trying to set the color depth.

Never mind, turns out that it just shows that error if there's no changes to apply.

well you shouldn't close this, that's a valid bug.

Perhaps we can add this to the readme so newbies ilke me aren't confused.
