Whilst true, it's more accurate to say the monitor market is hostage to the economics of LED panel manufacturing.

LEDs are normally produced as very large panels on production lines where every panel is made to a given PPI (and upper bound on the refresh rate).

Of course the technology mix is the technology mix, but the industry is built around reasonably large investments in these production lines, amortized across the entire screen industry.

A 27 inch 1080p monitor and a 24 inc 1080p monitor are produced on distinctly different production lines as it were, as they have a different PPI. But a tiny screen with the same PPI as said 27 inch 1080p likely came from the same factory in Korea.

Apple's panels are actually produced under contract by LG in Apple specific production lines, hence they can obtain exotic PPIs. Because they promise to use the line's capacity for multiple years.
