My real question: how do I get 1600x1200 (the native resolution) out of
this thing?

Anyone reading my previous X posts will note that I have Xinerama
working on my laptop with Radeon 7500, in a laptop, with laptop LCD as
Screen 0 and this NEC as VGA->DVI-A external Screen 1.

The display is fuzzy - as in actively blurry like a CRT scanning at the
wrong frequency or something (it's not just out of focus) - at all but
1024x768 (or something near that).

According to the NEC manual, specs are:

Section "Monitor"
   Identifier  "NEC"
   DisplaySize 410   310   # mm
   HorizSync   31.5-91.1
   VertRefresh 50-85
   VendorName  "NEC"
   ModelName   "LCD2080UX+"
   Option      "DPMS"
EndSection

Thanks in advance
