Hi.  I was hoping perhaps someone here could help me.  I recently was given 
a nice 20 inch monitor by a guy who was going to a flatscreen, and didn't 
have space in his apartment for the older monitor.  He was running it on a 
mac, with an adapter which had dip switches.  From what I've found out, I 
think this is so you can run an IBM monitor on a mac (not sure).  The cable 
ended in RGB and the black sync wire.

After a little digging, I was able to buy a vga cord that had the four 
outputs.  However, I tried to connect it, and the monitor looks all 
scrambled.  I checked the inputs, and they're all set.

My computer is a P3-500, running with a Voodoo3-3000 card.  There are no 
distinguishing marks on the monitor to tell me who makes it, or what model # 
it is.  There's a serial #, 1894470020, with a small DM subscript 
underneath, on the back.  Digital Machines?  The controls on the bottom of 
the monitor are v-stat,h-stat,v-cent, brightness,contrast, power.

I'm hoping to find out what make/model this monitor is, and what the 
refresh,resolution, and such should be.  There's a utility where I can 
change the refresh of my video card.  It might only work for windows, but 
that's all I work in anyway...I can stand it garbling until windows boots. 
If I have to, I'll see about getting a Gemini card, but I'd rather not if I 
can avoid it.

I've included links to some quick pictures I took of the monitor, as well as 
the adapter for the mac, in case that'd jog anyone memory.  Thanks for your 
help in advance.

The little dongle connector actually translates the signals and that
is the cause of your problems.  You need to figure out the correct
sequence for signal translation.  Therefore, please provide more info
on the dongle, is possible.

I was taking a look at your adapter and it looks filthy.  This is
good, try to move the dip switches that are "clean" and see if the now
exposed length is dirty.  If so, you may have the right configuration.
 Good luck.
