Isn't pin 4 strictly a self-test pin, designed to
make an unplugged
monitor give some illumination on the screen?
Not sure to be honest; I just grabbed a copy of the first pinout I found,
mainly because I assume there are a few different flavours out there anyway
(older equipment not supporting DDC etc.)
Any
suggestions? Do I just need 76ohm resistors to ground on the RGB lines
It might well be just that (well, 75 Ohm resistors would be the
'stnadard').
Yep, I thought they were probably supposed to be 75...
I konw some VGA cards sensed the load resistance on
the RGB
lines to determine if they were driving a monochrome (only loaded the 'G'
line iIRC) or a colour monitor.
That's what I was wondering, if it was something like that. I like Chuck's
suggestion about the ID lines though, I'll give that a go first.
(It's actually my modern heap-of-junk Dell laptop that I'm fighting with; it's
got some curious fault where the LCD display doesn't always un-blank after the
lid's been closed and opened again. Does it in both Windows and Linux, so I
think it's a firmware/hardware fault somewhere. Switching to external CRT and
back again cures it though, but it'd be nice to be able to do that without
actually needing a CRT plugged in :-)
