No, it won't. I don't know exactly which model that is, but I can tell
from the 'M' in the model number that it is a Macintosh monitor, and no
Mactinosh-specific monitor will work on the IIgs.
The Mac normally uses VGA-like output frequencies, with progressive scan
(no interlacing) producing at least 340 lines of video at refresh rates
of 60 Hz or higher and horizontal scan frequencies starting around 30
kHz.
The IIgs (along with every other Apple II) was designed to be more or
less compatible with television, so its video output is much slower: 50
or 60 Hz refresh, but only 200 lines per screen and the horizontal scan
rate is about 15.75 kHz. It doesn't use interlacing.
The IIgs RGB monitor (A2M6014) is designed to work within these
specifications, and will not work on most Mac models. (It is possible
to use it with some video cards, but only in a really ugly 400 line
interlaced mode.)
Mac monitors are designed to work with the Mac's higher scan frequency,
and are not able to sync with the much slower signal produced by the
IIgs.
If you cannot locate the genuine Apple IIgs RGB monitor (which is called
an "AppleColor RGB" monitor, just like some of the earlier Mac
monitors), you can use the RGB monitor from an Amiga 1000 or Atari
520ST, which have similar video output. Old multi-sync analog RGB
monitors were also able to support TV-like video sources, but anything
in the last ten years (or more?) won't work on the IIgs.
Even older machines used digital RGB (Apple ///, some Apple II video
cards; the PC had CGA and EGA). These won't work on the IIgs either,
since it generates an analog RGB signal.
The Commodore 1084s can be easily wired to work with the IIgs.
I have been using one for the last 5 years or so, and it is a cheap
option if you can't get the genuine Apple variety.

I have MANY of the original monitors that came with the IIgs, along
with data cables. I am willing to sell them for the cost of shipping
alone.. The shipping weight of the monitors is about 25lbs., in a
20"x20"x20" box. You can go to www.usps.com, to calculate shipping
(my ZIP is 01473, Massachusetts, USA). Be SURE to note on the
calculations page that the box is oversized (more than 17" high),
because that carries a surcharge....
You can email me off-list for more details, or if you are interested.

It is a Macintosh "High Resolution Monitor" which came with the
original Mac II's.

Just hacking away...
Remove nospam to reply.
Could you explain how to perform that hack ?
Is it possible to do it with CBM 1940s monitors ?
Thanks,
Martin.

The CSA faq's contain some info on using a 1084d monitor (the one with a 9
pin d connector)
with the IIgs but make no mention of the earlier and more commonplace 1084.
The earlier 1084 has no composite SYNC input on the 6 pin Din Analog input,
only seperate HSYNC and VSYNC inputs.
Internally the HSYNC and VSYNC signals are just joined together through a
couple
of 480 Ohm resistors.
If you connect the composite SYNC output of the IIgs to either the VSYNC or
HSYNC
inputs of the 1084 (BUT NOT BOTH!) it works just fine.
I used a lead as follows with success:
Apple 15D <-> 1084 6Din. (ANALOG)
13 GND 3
2 RED 4
5 GRN 1
9 BLU 5
3 SYNC 2 (HSYNC)
Enjoy
