List of monitor names

Can one get a list of monitor names that I can use to tell emacs where to put the frame?

How do you plan to use the monitor names to tell Emacs where to put a
frame?

Perhaps the user can get the monitor names and see which monitor he wants to work in.

For me the solution was based on https://askubuntu.com/q/702071/80483
and https://askubuntu.com/q/702002/80483; basically you run `xrandr` and
parse its output.

Well, look no further than display-monitor-attributes-list, which uses
RandR to obtain the same information, but without needing an external
program.

(Unless, of course, your X server only supports Xinerama, in which case
it falls back to that.)

With "display-monitor-attributes-list" I get

(((geometry 1080 1152 1366 768) (workarea 1080 1152 1311 768) (mm-size 344 194) 
(frames #<frame *scratch* 0x16f3510> #<frame Speedbar 0x2b84190>) 
(source . "Gdk")) ((geometry 0 0 1080 1920) (workarea 0 0 1080 1920) 
(mm-size 477 268) (frames) (source . "Gdk")))

But still nobody has told me what frame should I use for the initial frame (seems it
is usually *scratch*).  What input should frame be in the command "(frame-outer-width frame)".

Doing (frame-outer-width "*scratch*") gives

Debugger entered--Lisp error: (error "*scratch* is not a live frame")

  signal(error ("*scratch* is not a live frame"))

  error("%s is not a live frame" "*scratch*")

  window-normalize-frame("*scratch*")

  frame-outer-width("*scratch*")
