I can't seem to find any information at all about this monitor. Does anyone know what the 2nd 25pin input does?
I have no clue what I'm doing! If you want to watch me fumble through all my retro projects, you can watch here: https://www.youtube.com/user/MrDavejustdave
The Olivetti M24 / AT&T 6300 used a DB-25 connector for video which was software compatible with CGA but output an analog signal to the monitor (like VGA would later). But the M24 was early 1980s and this is a 1989 monitor, so not at all sure it would be for that. If you can't find documentation, you could open up the case and see what is hooked up to the connector...
IIRC, I saw a setup not unlike that on one of EEVBlog's dumpster-dive vids; it turned out to be an extra connector for a touchscreen setup. Could it be something like that?
I find it strange that that monitor doesn't have the Gateway 2000 logo from that era:

Now for some blitting from the back buffer.
I have the same monitor (mine is not relabelled as Gateway but branded MAG Technology) and question about the DB25 port function.
I suspect it is an analog video input as I found evidence that this model could be a multisync monitor, not just an EGA one. I'm trying to figure out the pinout...
MAG PMV14AC EGA CRT monitor: is it multisync VGA capable?
@DaveJustDave did you happen to discover something more since your original post?
