PTravel quoted "lines of horizontal resolution" figures. That's (ahem!)
a measurement of horizontal resolution, and it is measured by using a
resolution test target that has _vertical_ lines on it.

You're confusing those figures with the number of "active" scanlines in
video signal, which has more to do with vertical resolution.
