[comp.sys.ibm.pc.hardware] CGA/EGA/VGA/SVGA Specs -SUMMARY

uchuck@uncmed.med.unc.edu (09/21/90)

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.

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. (I didn't say that..)
