Blurring is more likely to be caused by a low monitor bandwidth.  My
Viewsonic 15GA has a reasonable bandwidth of 86MHz, and my current
1152x864 at 16bpp gives quite sharp output.  1280x1024 at 8 bpp was a
little blurred.

(After getting my new M/B and video card, my old, cheap monitor
actually got sharper.)

The video card can only push data through at a certain speed limited
by the RAMDAC.  I see from my X startup that at 16 bpp, this is 95
MHz.  This places a limit on the combination of resolution, refresh
rate and colours.  The 2400 may be better than the 2000.

See /usr/doc/X11/VideoModes.doc for a complete discussion / tutorial.
