You're wasting your time.  Even at a stripe pitch of 0.23 mm, which would be
very good for a monitor (my own Sony is 0.26), the highest resolution you
can support on a 21" monitor is about 1700x1275; anything beyond that, and
individual pixels will be concealed by the phosphor stripes.  The best I can
do on my 20" Sony is 1600x1200, and it just so happens that each pixel just
about covers a phosphor triad, so there is no point in going any further for
a monitor this size.(I'm happy to report, though, that the Sony monitor
still manages to resolve individual pixels, even at this rock-bottom minimum
size.)

So, unless you plan to get at least a 26" monitor, 2048x1536 will do you no
good at all, and may even present problems (because details covering
individual pixels will not be visible on the monitor).
