Thanks, a few comments below.

If this is supposed to be used as part of mode-line display, then no.
Signaling errors in the middle of redisplay is generally a bad idea,
because they cause another redisplay cycle, which again signals an
error, and Emacs just freezes.

The doc string should say something about what "the current monitor"
means, or have a link to where that is explained.

> +DISPLAY can be a display name, a terminal name, or a frame.

"Terminal name" or "terminal object"?

> +(defun display-monitor-geometry (&optional display x y)
> +    "Return the geometry of the current monitor.
> +DISPLAY can be a display name, a terminal name, or a frame.

Same here, on both counts.

Why is this in xmenu.c?  Is the problem unique to X window system?
