DISPLAY can be a display name or a frame. If DISPLAY is omitted or nil, it defaults to the selected frame's display.

For character terminals, each character counts as a single pixel.

For graphical terminals, note that 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.
