Salute,

I just wanted to post my settings, perhaps someone is in search.
Prism Excelsior Pro, 1MB: clocks  25 28 34 36 34 36 68 69

MAG 17H at 1152x900: 
 69    1152 1172 1288 1368    900  909  933  937

and at 1024x768:
 69    1024 1092 1220 1344    768  786  791  810

both non-interlaced. 1024 is at (so's the display saying) 58kHz and
72.5Hz, 1152 at 56.75kHz and 61.5Hz.

   bye
     Chris
