I think, this is only slightly off-topic, since it is about a 68040 machine
and monitors are generally important for Quadras, too.

I want to use a specific monitor on my NeXT Colour Station (68040).
A friend of mine wants to give me a Ikegami 20 inch Trinitron monitor for
free, but the heavy piece has to be shipped over a few hundred kilometers,
so I want to clear this first.

The NeXT monitor specs are:

Horizontal Scan Rate: 61 KHz
Vertical Scan Rate: 68 Hz
Sync-on-green

So, the monitor, if not an original NeXT monitor, has to be a multiscan
monitor to match the requirements of the NeXT.

The monitor I am interested in is the Ikegami CT20HB Rev. G
I have the needed 13W3 to BNC adapter.

Well, you maybe know these self declared "monitor authorities" like
www.monitorworld.com or www.si87.com. I looked on their pages for the
technical specifications of the Ikegami display, but I found most confusing
information:

http://www.monitorworld.com/Monitors/ikegami/ct20hbrevg.html

the description of the ikegami display reads there:
H Freq/ V Freq: 59.52; 47-65 Khz / 73.68; 54-80 Hz
The site says it is fixed frequency!!! But then again they write that the
monitor scans horizontally from 47-65 Khz and vertically from 54-80Hz...

I found more irritating data about "fixed frequency" monitors on those
sites:

For example, look at this:
http://www.si87.com/MonitorSolutions/sun/gdm20d10.html

It is about the Sun 20D10 which specs read:
H Freq/ V Freq: 60-82 Khz / 50-150hz
But this site states that it is a fixed frequency monitor. False?

Same here:
http://www.si87.com/MonitorSolutions/sgi/gdm20d11.html#MACcable

Can this serve as an explanation:
Maybe they also consider a monitor to be of the fixed frequency type if it
scans only through the upper area of frequencies. You know, on a PC, the
monitor has to be able to handle also very low horizontal frequencies like
around 34khz - in the Bios screen or in Dos.
So - maybe - a monitor is considered to be of the "fixed frequency" type
generally, if it is not PC compatible, even if it is a multi-scan monitor in
the  small range of higher frequencies.

To end with a clear formulated question:
Is the Ikegami, which has
H Freq/ V Freq: 59.52; 47-65 Khz / 73.68; 54-80 Hz
a fixed frequency monitor or a "small range multiscan" display that would
work on the NeXT?
