Thanks for the monitor info. Had a quick look at the 31” 4K Eizo and see what you mean, even more expensive than the computer!

Can’t believe its the only 4k option they do?
The Benq SW321C Pro does look like a nice monitor (thanks
@Roc1). Uniformity adjusted like the Eizo’s, 99% aRGB and 16 bit LUT. Not a proper 4K panel but half the cost of the 31” Eizo. Any experience of these?
