In the old days, there were separate screens for different monitors.
That still happens, but rarely.
Now there is only one screen. Both monitors are on that one screen.
xrandr --auto puts both monitors at the same spot. If you want them to
be side by side, displaying different parts of the same screen, use the
xrandr options for right-of or left-of. An example is shown in the
xrandr section.

The screen size is calculated from the size of the monitors. No other
configuration in xorg.conf is needed unless the monitor EDID does not
supply enough information, and that is vanishingly rare any more.
