As I recall, some years later than this (referencing EGA monitors from the 80s), a 14 inch 1024x768 capable 75 Hz capable SVGA monitor with a reasonable dot pitch of 0.28, nothing special, something you might find bundled with a 386DX/40 or similar from a clone builder was something like $400 in 1992.
This would be the inflation adjusted equivalent of $970 today.
So basically like buying a really nice super high refresh rate 32" gaming display.
