Well, if they use it on a 19" monitor with the standard 4:3 aspect ratio
then they'll end up with 1505x1128. Would _you_ buy a monitor with that
native resolution?
The dot pitch is dictated by the native resolution and by the screen
dimensions. If for a given physical screen size the dot pitch is made
smaller, then the native resolution necessarily increases. That's simple
geometry. If the native resolution is one that is not widely supported by
standard video boards, then even if they can be made to support it doing so
is enough of a nuisance to kill the market for such a display, so the
manufacturers make them in standard resolutions.
