[comp.sys.ibm.pc.hardware] EGA card + mono monitor

f89ba@rigel.efd.lth.se (08/22/90)

I have heard that it's possible to display EGA graphics on
a standard MDA mono monitor. I currently have a mono monitor
with the following data:

  * 20 MHz bandwidth
  * 15.75 AND 18.432 kHz hor. scanning frequency
  * 47-63 Hz vertical scanning frequency

This monitor is currently used in conjunction with a
CGA/Hercules card, and it's perfectly capable of displaying
shades of gray.

My question is: Will this monitor be able to display EGA
graphics? If it is - will all the EGA modes work, like
640*350 in 16 shades of gray? If my information is correct
the horisontal scan. freq. of the EGA is appr. 21 kHz, and
this fact alone would make my monitor incompatible, or am I
missing something here?

By the way, the card I'm planning to buy is a 1024*768 Super
The card uses a Trident chip set. It's NOT an original IBM EGA 
or an EGA-only card.
