That matches what the "Displays" settings shows, no?

If you have a patch, I can test it with the various external monitors
I have.
And a synthesized name: (((name . "3200x1775@0,25") (geometry 0 0 3200 1800) (workarea 0 25 3200 1775) (mm-size 599 339) (frames #<frame *scratch* 0x7f7c7009d430>) (source . "NS")))

We could use something like a UUID that's more opaque.

I haven't made either name bi-directional yet to allow specifying it when operating on frames.

Thanks for the help.  Patch attached.
