	From what I can see, the STB ERGO card is capable of driving the
monitor at a faster vertical refresh rate.  From the specs that I had them
fax me on the card:

	mode		resolution		Hfreq/Vfreq
	----		----------		-----------
 11h, 12h, 2eh, 79h,	640x480			31.5KHz/60Hz
 101h						38.2KHz/72Hz

 29h, 30h, 6ah, 70h,	800x600			37.8KHz/60Hz
 102h, 103h					45.6KHz/72Hz

 37h, 38h, 72h, 73h,	1024x768		48.6KHz/60Hz (non-interlace)
 104h, 105h					56.3KHz/70Hz (non-interlace)

 37h, 38h, 7eh, 7fh,	1024x768		35.5KHz/88Hz (interlace)
 104h, 105h


	I am considering getting this board since it will do 1024x768 in
256 color with 1Meg of video RAM.  Has anyone tried this board that has
comments, good or bad?

	On another note, I'm looking for recommendations on a 20" color,
multi-scanning monitor.  I've seen a few ads for a Sampo monitor in the
$1300.00 range, anyone used this monitor?  Is the price a little too good
to be true?

	Thanks,
	Terry
