Well, there's

(x-display-pixel-width (selected-frame))
=> 1920

(and height), so it seems like we're covered...  (I don't know whether
that function works on non-X systems, though.)

And the function above also returns the same size data, but as an alist:

(frame-monitor-attributes (selected-frame))
=> ((name . "eDP1") (geometry 0 0 1920 1080) (workarea 0 27 1920 1053) (mm-size 
310 170) (frames #<frame movie.el 0x563f20223a30> #<frame emacs 
0x563f22915f10>) (source . "Gdk"))
