Gregy and Gerald,
Gregy's reply to Sergei's question prompted me to research some of the books
that I have, most of which I don't understand, some of which I pretend to
understand, and the rest of which I will pass on in hopes that someone will
understand. Now, if you understand that ....
In Scott Mueller's, "Upgrading and Repairing PCs" 6th Edition, Page 1137, it
states,
"Monitor ID Pins
The following table shows the settings used for the Monitor ID bits for
several different IBM displays. By sensing which of these four pins are
grounded, the video adapter can determine what type of display is attached.
This is especially used with regards to monochrome or color display
detection. In this manner, the VGA or XGA circuitry can properly select the
color mapping and image size to suit the display."
The table shows:
Display: 9517
Size: 17-inch
Type: Color
ID0: Ground
ID1: No Pin
ID2: Ground
ID3: Ground
Hope this helps.
