As you problably know, my 5153 monitor didn't ship well, and I'll need a new CRT to get it working (I assume it's pretty expensive and difficult to get the right one).
So, now, I'm looking at some 3rd party EGA monitor in the back of my classroom (it looks like an old VGA monitor, but it is EGA), and I wonder if I can use that with my CGA card.
But how compatible are they? many sites states that EGA monitors can handle the rates and signals of the CGA, but that it got some of the high-intensity colors wrong. Another site states that one of the sync signals are positive edge triggered instead of negative edge triggered (or opposite).
The EGA monitor I'm looking at got an "Invert" switch on the back, maybe that's for CGA compability...
But can anybody clarify what's compatible and not compatible of behavour of CGA and EGA monitors?
