Itʼs a late 2018 macbook pro 13", i7 cpu. The external monitors are:

(display-monitor-attributes-list)
(((name . "Monitor1")
  (geometry 0 0 1920 1080)
  (workarea 0 23 1920 1057)
  (mm-size 594 334)
  (frames #<frame *Summary gmane.emacs.bugs* 0x7fcda78819b0> #<frame *ielm* 0x7fcdad8efa80>)
  (source . "NS"))
 ((name . "Monitor2")
  (geometry -1920 0 1920 1080)
  (workarea -1920 0 1920 1080)
  (mm-size 594 334)
  (frames)
  (source . "NS")))

so not 4k, and I normally run with multiple non-maximized frames (but
my testing was with a single default frame).

Robert
