The Toughbook CF-C1 has a VGA output port which allows you to connect a monitor.
But by default, in Lighthouse 64 Puppy Linux 6.02 Beta 2, the monitor will only mirror what's on the laptop's screen.
Fortunately, I finally stumbled across a way to make each screen show different things! I found it on this Stack Overflow page:
It instantly worked!
Also, when a 4:3 monitor is connected, the laptop's screen gets resized to match. I was able to put the laptop screen back to its original size with this command:
But, after doing that, the touchscreen only works right if the monitor is mirroring the laptop's screen instead of displaying different stuff.
But with the laptop's screen restored to its original size, the mirroring 4:3 monitor can't fit everything on the screen anymore.
The Redshift screen-tinting software helps with the laptop screen's appearance, but not as much as I hoped. My Windows 7 CF-C1 screen still looks much better, I think maybe because the Intel HD Graphics software in Windows 7 lets you adjust the screen saturation.
Maybe Redshift could be modified to make it capable of adjusting the screen saturation?
The exact command I used on my own system was:
xrandr --output LVDS1 --right-of VGA1
However, I don't yet know how to make the touchscreen work right while doing this.
xrandr --output LVDS1 --mode 1280x800
So, this all still needs perfecting. But, at least it's already useful, since it's really nice to have more than one screen. And also, probably most monitors look much better than the CF-C1's washed-out-looking widescreen.
