Monitor size?
Budget?
Any other bling you want it to have?
Since there are plethora of 2K, 144 Hz monitors out there.
Though, for photo editing, i'd go with VA panel monitor, since they have good contrast ratio of min 3000:1, while TN and IPS panels usually have it 1000:1, whereby blacks aren't black, but instead gray or some form of blue. Only VA panel will produce deepest and richest blacks. <- This, IMO, is crucial for photo editing (at least it is for me, since i too do photo editing).
