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.

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.
- kevin_thibedeau 2y agoIBM 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.
