Why are these so expensive? You could get a top-of-the-line new 5k iMac for that greyscale 2048 x 2560 monitor. Presumably it's all the calibration and certification that goes in, but wow those are pricey.
The linked greyscale monitor above only had 8-bit greyscale, but describes it as "256 levels of gray out of a palette of 3826". Does that mean anything significant?
Yes, it means the monitor has an 8-bit host interface but each value on the range [0,256) is mapped to a range of levels [0,3826) that the panel can actually produce. The number seems weird, I'm not sure why it would be 3826. Maybe someone can explain.
