Hi people. I have a Mitsubishi Diamond Pro 900u (nowhere near on-topic
but I figure people here might know better what causes this kind of
problem). If I provide it with a sync-on-green signal to its BNC
connectors (It has five, I connect three), the monitor syncs up just fine,
but all the areas that are black show up with a green cast. The white
areas show up just fine. I haven't looked at an image with color yet, but
I would guess that all the colors would probably be shifted towards the
green. Any ideas?
Peace... Sridhar

Sounds like your minitor needs a minor tweaking of the green screen
control. What is best is a stairstep input, and you can set your
screens and channel gains for an acceptable picture, i.e. greys, with no
hint of color. As the CRT ages, these will wander a bit.

It may be
a similar problem like my CTX has. The manual says it
can do SOG. But when I first connected a SOG signal, nothing. I had to
build a sync separator to get things going. Later I discovered that
SOG works, but only with a high green level all over the screen.
(e.g. white ground and black characters) My fist attempt was with
the boot prompt of a HP Apollo 433t => black ground and white
characters => no high green level => no sync. So this is the guilty
of a poor designed sync separator in the monitor.
Blame the monitor manufacturer.

Olkay, it can. It sonds like the video is clamping on the sync tip, and
that in turn raises the pedestal (zero level) causing the grenish
tinge. Is there a way to set the monitor up for SOG?
