Just installed a nice Compaq V1100 monitor, but
it's a bit too dark -- and the adjustment button gets
1. message in Spanish (not English)
2. that the adjustment menu is disabled (bloquado).
How can I reset this to factory defaults?

Try PDF page 25 here. After looking at a brochure from Compaq,
where several models had identical feature sets, including
"control lock", I found a manual for a different monitor P920 19"
with a potential recipe.

"Press and hold the Enter () button
for 10 seconds or more to Lock or to Unlock"

Once unlocked, you can switch from your fluent Spanish,
to another language.

HTH,

Bingo -- now cooking with gas . . .
BTW, did your Compaq documentation happen to
mention any monitors with "Input B" connectors on
the back panel -- five of them, CATV coax type,
marked R, G, B, H/H+V, and V. These are obviously
not needed for everyday function but I should like to
know what they are for, in case I add those Audigy
cards still in the cupboard . . .

I have a monitor that *only* has the five BNC connectors
on the back. The reason for that, is using coaxial cables
for sending the signals, is the highest quality way of
doing it. The VGA 15 pin connector, by comparison, is a
kludge. For example, if I wanted to send a 2560x1600 signal
to a CRT monitor, I'd actually prefer to do it with the
five BNC connectors (three color signals, two sync signals).
BNC connectors have better RF characteristics (match the
cable impedance better). The VGA connector pins could
cause reflections and ghosting at extremely high
resolutions.

The other advantage is, you could buy low loss coaxial cables,
if you were trying to send the video a longer distance.

But then, of course, the problem is, that no PC video card
has five BNC connectors on the faceplate :-)

My monitor comes with an adapter cable for normal usage.
It has five BNC connectors on one end, and a VGA connector
on the other end. So it is not an inconvenience for me
(especially as the monitor is retired and sitting in my
basement).

For resolutions like 1280x1024, this is likely a "don't care"
as a consideration.

If you want to see another approach to the problem, Sun had
a good method. They use a 13W3 connector. It has miniature
coaxial connectors for the RGB signals, to reduce reflections
and give more ideal high resolution transmission. This would
be an improvement over VGA, so you wouldn't need BNC
connectors.

You also can share your monitor between two computers by switching the video
out on one of them. The monitor automatically detects the other valid input
signal and displays accordingly. I've done that with my Lyiama for years
switching it between my gateway and the main computer.
