I have gotten replies to my post but nothing about making a VGADB monitor
entry. The vertical frequency is not a typo. I'll let you know or post
something if there is a change.

Subject: Re: [9fans] Monitors and VGADB
Mark,
I just installed Plan9 on my pc yesterday. I have the same monitor as you
do
and used the vgadb entry for the Micron 17FGx. This is probably not the
correct
thing to keep running it but at least it got something up on the screen for
me
to work with. I looked at my user's manual for the Micron 700FGx and
noticed a
difference in one of the numbers you posted. I wasn't sure if it is a typo,
but
what I have is indicated below. BTW, if you got any replies to your posting
I would
be interested in how to modify my vgadb correctly too.

aux/vga won't recognize your monitor
per se, but if you set monitor=micron-17FGx you
should be all set. i've been using a micron
monitor with the cm751u defn to run at 1600x1200
and it works fine (yes it's a hack).
an odd side-note: i plugged my (real) hitachi cm751u
into a win98 box the other day, and the win98 box
figured out that it was connected to a "Hitachi CM751"
(new hardware detected!, etc.). does anyone know
how it did that? i thought the video output
cable was one-way.
for translation from the manual to the
numbers needed by vgadb, the best reference
i know of is the XFree86 Video Timings HOWTO
(formerly the Hitchhiker's Guide to X386
Video Timings).

DDC
Short for Display Data Channel, a VESA standard for communication between a
monitor and a video adapter. Using DDC, a monitor can inform the video card
about its properties, such as maximum resolution and color depth. The video
card can then use this information to ensure that the user is presented with
valid options for configuring the display.

DDC
and I'm pleasantly surprised to know something Russ didn't know
that's like something I can tell people about :-)

No, modern monitors use "DDC" to communicate their vital data back to
a DDC compatable video card.
There's a linux program that supposedly exercises this, but I didn't
have much luck with a Nokia 447x talking to a #9 771.
