Is there any way to do a high resolution screen capture?

All of the Windows-XP built-in Print Screen stuff is crappy compared
to what I'm seeing directly (1280 x 1024).

As others have alluded, screen capture simply captures the pixels on
your screen exactly as they are so the problem isn't with screen
capture, per se, it's what's done with it later.

The confusion comes from 'DPI'. DPI has meaning to printers, as
that's how they print, but none to the display screen. By that I mean
a 1280x1024 screen is 1280x1024 whether on a 15" screen, 20" screen,
or projected to wall size and, clearly, those are different 'DPI' for
the same pixels.

If you can't be bothered working it out, here is a page that shows you
the actual DPI for screen diagonal and resolution (valid only for
square pixels).

Most of my ones in current use are 100-135 DPI.

Note that Fax resolution is around 200 DPI (and that's using the
"fine" setting).

A display with 0.25mm pitch pixels is about 102 DPI.

We're still a long way from having a reasonably affordable display
(say $2K 2010 dollars) that will show a window containing 2-page
letter or A4 spread with 600 (or even 300 DPI) color. Say 10:1 for 300
DPI and 36:1 for 600 DPI. If Moore's law holds (y= 2* ln(36)/ln(2),
right? )we could see it in another decade or so.
