Does anybody have a manual for this monitor? It has a switch on the back labeled as S.O.G. and TTL

what is it for? Googling around give nothing really... 🤔

As far as I tested the monitor it works ok.

Yes, sync on green. Which means sync timing is inline between green video signal bursts. Not common in PC but common on specialized computers like SGI, Sun, etc.

TTL sounds like digital RGB, so maybe EGA/CGA is supported ?
Does it have a DB9 connector on the back ?

Nope. Looks like this is VGA only monitor: https://www.download.p4c.philips.com/files/1/ … 0c_dpi_eng.html
Last paragraph is about sync-on-green.

So if I understand correctly... TTL shoudld be used always, with monochrome or color source?
I had some weird stuff going on while testing the system yesterday. But have to check first on other monitors (lcd and crt) before I jump to conclusions.

Yes BUT you need normal analog video and not MDA/CGA/EGA, it seems that TTL refers to the sync signals (which is correct but not the common definition of the word, when it comes to video inputs);

if you know how to use a BNC computer monitor with that specific source, and it would use 3 cables, select SOG, if it uses 4 or 5 cables (as with standard VGA and above) select TTL 😀
