Option 1 is to set it using a configuration file "snippet" in the
/usr/local/etc/X11/xorg.conf.d directory, like the traditional
xorg.conf: only put section "Screen", subsection "Display",
setting "Modes" with the screen size you want.
For example, it could look like this:
Viewport 0 0
Modes "1920x1080" "1280x800"
You could then probably even use Ctrl+Alt+[+] and Ctrl+Alt+[-]
to switch between the two modes (not tested, but old-fashioned
X could do that).
Option 2 is to use xrandr in ~/.xinitrc with the --size

Similar to the approach for the laptop's screen. You can even
use xrandr from inside a running X session to change the screen
size dynamically. It's also a convenient tool for experiments.
(Side note: I set up a Dell Latitude D630 laptop with a screen
size of 1280x800 and an external monitor of 1920x1080, but I
use Mate on this specific system which offers the native screen
size in its configuration program.)
