Well, yes and no. I do agree with you, VGA firstly is (was) a graphics controller, a framebuffer device.
Albeit a very flexible. It can be programmed in a way that it can do certain operations on its own.
But in people's mind, it also is a connector. The DE15 D-Sub connector existed before, but the pinout and blue colour made it de-facto the "VGA connector".
Today or since the 90s, these blue connectors are specifically made with VGA in mind.
The term "VGA" also officially stands for 640x480 resolution, while "Super VGA" stands for 800x600 (the original SVGA mode)..
- Ironically, DOS gamers do associate 640x400@256c or 640x480@256 as SVGA, too.
Which contradicts with the video resolution terms from the DTP/CAD/CAM fields.
Technically, what DOS gamers always used to call "VGA" (320 by something) really matches a low-resolution named "QVGA" (quarter VGA).
- The term was often used in conjunction with webcams and PDAs/Pocket PCs in the 2000s.
ModeX, the unchained mode, often was used for 320x240 games/emulators but also worked with 320x200 resolution.
It's just so much better to be able to have nice square pixels and a contiguous video memory!
Perhaps that's why unchained 320x200 was somdtimes nicknamed "ModeY" (mode why)? 😉
Anyway, these are just my two cents -
I don't really mean to judge or play the role of an educator.
I'm just a visitor who has seen things come and go.
Most of you already know these technical things inside-out, anyway. Likely better than me.
I just wanted to provide some little summary for all the guests that wonder what it's all about.
