x-display-pixel-height is a built-in function in `C source code'.
[...]
On "multi-monitor" setups this refers to the pixel height for all
physical monitors associated with DISPLAY.  To get information for
each physical monitor, use `display-monitor-attributes-list'.

And since you are (presumably) on Windows this coincides with the
documentation of SM_CYVIRTUALSCREEN:

The height of the virtual screen, in pixels. The virtual screen is the
bounding rectangle of all display monitors. The SM_YVIRTUALSCREEN metric
is the coordinates for the top of the virtual screen.

So what does (x-display-pixel-height) return on your system?
