Below are the salient responses I received. It was thought that SVGA is not standard and the second response confirms that hypothesis. Thanks to all that responded. Chuck RESPONSE 1 --- From: tengdahl@hulk.hut.fi Subject: CGA/EGA/VGA/SVGA Specs Type Resolution Horizontal Vertical ---------------------------------------------------- CGA 320x200 and 640x200 15.75 kHz 60 Hz EGA 640x350 21.85 kHz 60 Hz VGA 640x480 31.48 kHz 60 Hz Those are standard frequencies used. SVGA frequencies are not standard. They depend on the card manufacturer and the monitor settings.

Just out of curiousity what are the horizontal and vertical frequencies for hercules graphics type displays? Just a side note, but it's amazing how many people don't realize the benefits of HGC displays, they have higher resolutions than anything but super VGA displays, true there's only two colors. 720x348 is better than standard EGA, and how many of us can print in color. ;) Color is nice though.
