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

uchuck@uncmed.med.unc.edu (09/14/90)

Our TV engineer needs to know some specs on the different monitor modes.
Can anyone fill in the following table and/or add to it?

			 Vertical      Horizontal
  Type     Resolution    Frequency     Frequency
  ----     ----------    ---------     ----------
  CGA      320 x 200
  EGA      640 x 350
  VGA      640 x 480
  SVGA     800 x 600
  SVGA     1024 x 768

  Are these standard or does it just depend on the card manufacturer?
  Lots of questions, need answers.  Will summarize and post back results.

One trivial contribution:

CGA is not only capable of 320 X 200; it can also do 640 X 200.

Scan rates are normal TV rates: 60 Hz and 15,750 Hz.

BTW, 640 X 200 is monochrome.
