The big differences were typically moving the analog knobs into buttons and sometimes an onscreen display (sometimes with saving of configuration per detected video mode). That's pretty much the primary obvious difference (and these differences began mostly in 1995-97, so it's not exactly out of the ordinary for a Pentium build)

and of course you get into the differences between all these differing vendors with differing shadow masks, the blurrier dot pitch in early monitors etc...

At higher resolutions like 640x480 (Yes this is actually pretty high compared to even consoles like the Genesis/Mega Drive) this begins to matter a lot less. I see 0 problem with using that monitor with a DOS or Windows machine.

Also make sure the pinouts of both the VGA card and the monitor do match.
I'm speaking under correction, but I believe the meaning of the extra pins changed over the years.
Could quite be possible some of them (DDC, Monitor ID, etc.) are now accidently grounded.

I've never had a problem in my life with that. I doubt that it would be an issue.

Who knows ? In case of doubt, someone just makes a basic adapter with RGBHV wiring.
As far as I know, there must have been at leat ~four different VGA generations..

Edit: Hm.. Was looking for that chart of mine, but can't find it right now.
Anyway, here are two links that show original and new VGA pinouts.:

http://what-when-how.com/display-interfaces/s … erfaces-part-1/

As we see, some of the pins like "test", "monitor id" got re-purposed for DDC1.
No big deal, but good to know nevertheless. 😀

Wow... didn't know I could learn this much just from posting.

I have another question...

I have Compaq S710 PE1123 Model CRT Monitor and I plan on getting a used PC with a QDI-P5I430TX-250 model motherboard from about 1998.

Would that have a compatible VGA port?

Sure, no problem. 😀

I was thinking of mixing early VGA stuff from the late 80s/early90s with more modern stuff..
Sometimes there are minor issues, like the screen beeing beeing monochrome and such.

That's why I was hinting about the possibility of compatibility issues. But it's no big deal, really.
If you ever encounter issues you can make an adapter. Either by making a cable or by using a 1:1 adapter/gender changer:

Just modify the adapter in a way, that only RGB, H/V-sync and ground(s) do remain. And maybe the ID-pin for colour also.
That's about the same as old professional monitors were connected (they had separate BNC connectors for RGB/HV/GND).

So don't worry, if it's a PCI or later VGA card everything should be fine.
I don't know about EISA/Vesa Local Bus cards, though. With these it's perhaps better to check the datasheets a little bit. 😉

No, my Trio32 works perfectly fine.

By looking at the pinouts I have real heavy doubt that anything would go wrong TBH. I have never had an issue, even when mixing an early 1990's IBM CRT with newer tech.

My Trio64V+ never had problem with my LG 710E(CRT) neither my Samsaung 732N(LCD).
