High DPI CRTs existed back then. That is a more likely explanation.

"High" being relative and constantly changing, of course. The SGI 1600SW from 1998 was 1600x1024 at 17.3 inches, so 110dpi. A beautiful thing, but not really like paper IMHO. https://bytecellar.com/2008/02/13/the_sgi_1600sw/ https://bytecellar.com/2008/02/13/the_sgi_1600sw/ && https://en.wikipedia.org/wiki/SGI_1600SW https://en.wikipedia.org/wiki/SGI_1600SW

  I think Apple and other people maintained that 150 DPI is around where you start perceiving a monitor to be similar to a printed page.

Considering the IBM "Big Bertha" LCD was an obtainable product in 2001, it doesn't seem too far-fetched that high resolution LCDs existed in some R&D labs years earlier. https://en.wikipedia.org/wiki/IBM_T220/T221_LCD_monitors https://en.wikipedia.org/wiki/IBM_T220/T221_LCD_monitors It's not quite a 4K monitor, but I'll tell you it was pretty amazing to those of us who saw it demonstrated back then. This was a qualitatively different thing than we were familiar with. And, as I recall, it took 2 or 4 DVI inputs to drive it from typical graphics cards of the era. A single display output could not drive these kinds of pixel counts.

  They started that project as Roentgen as I recall, and while they did exist there were eye-watering of expensive. Around the time Apple started delivering HiDPI displays there was still a bit of scrambling by everyone to get software to play nice on OSX and Windows. Always fun when a game doesn’t realize you’re on a 270 DPI screen and makes the main menu so small you can barely read it to change the settings.

  IBM had a CRT version of this before then. It worked the same by splitting the display into four quadrants. A Windows desktop only showed on one quadrant and you needed special software to use the whole display. The one we had at work was monochrome grayscale so it lacked the issues of dealing with a fine shadow mask. LCD panels in that era were still being hand buffed and the defect rate would be high when attempting higher resolutions.

    What was the purpose of a high resolution greyscale monitor at the time?

      High resolution greyscale monitors were used for medical imaging.

You could be right.
