By the time of the 6200/6300, I believe it was the Multiple Scan 14 and 15 that were being shipped with the Performas. Though, globally, a couple different manufacturers built the MS15, there are different enclosures with different ID numbers that will tell you who manufactured them. (UL listing or FCC or other regulatory body numbers.)
The performa monitors, and the Multiple Scan 14/15, get a lot more derision than I'd argue they deserve. "Less than stellar" is usually, honestly, pretty good. (This shouldn't be surprising, I argue this about basically everything.) It's not like this was SGI shipping a 640x480 shadowmask in the late '90s for its machines that exclusively sell for, absolute minimum, $5000. The majority of the Macs that existed and were sold were machines oriented toward home and education environments where budget concerns would win out over other concerns. Apple's cheap displays didn't specifically hurt to look at (any more than any CRT), display fewer colors, have unusually low refresh rates,
(Most of the rest of this is context thoughts and rambling)
In 1992 when the Performas launched, the Performa display cost a quarter to half what the ACHRRGBM did, and the 21MCD itself cost almost 3x what the ACHRRGBM did.
(per everymac, $305, $1647, $4599, respectively, in the USA)
Further, even in a professional context, something like the 21MCD or even 16MCD (which was ~750 in 1993, I think down from its 1991 launch price) were kind of task-specific displays, and ACHRRGBM or later MCD14 would be the default display for someone who wanted a "nice" monitor but didn't have a professional justification for spending much more on a big display.
The Multiple Scan 1705 (then 720) is probably the first Apple "budget friendly" (under $1000) 17-inch display, and that sat underneath the colorsync/applevision family that replaced the MS17/20 as high end displays. (Looking, everymac says the AppleVision 1710 was 999 and the MS1705 was 899, so both are a bit more budget friendly than what they replaced, I wonder at what point in the lifecycle the AV1710 was 999 though, the same monitor was sold under 3 different badges from 1997 to 1999, and the Studio 17 that replaced it in 1999 was $499, I'd have to dig through macworld to see, and, of course, EveryMac tends to do launch list prices, and that'll have floated around over the years, especially in the older days when the monitor models lasted longer.)
Right around 1997, maybe very late 1996, was basically the first time I saw recommendations for 17-inch monitors on home Macs, MacAddict recommended a 6400/200 and an AV1710AV plus some other stuff as a gamer setup. It's interesting to see how the prices on big displays have gone down over time. Heck, anything that had a long life in the '80s and 90s seemed to go down in actual street price over time so it's tough to tell what you could actually get, say, the ACHRRGBM for in 1992, especially if you were willing to buy one that was a few years old.
while writing this,
@Danamania was kind enough to look at some US magazines for me: in August 1997, the 1705 was $599, 1710 was 699 and the 1710AV was 799, which is way better priced than Apple's suggested price, I think this was basically the tail end of that specific era. (or EveryMac's information was extremely wrong because these displays would have only been a couple months old at that point.)
