@Matt_Gordon I have used NEC monitors for quite some time. My current one is the 27", PA272W. It’s has a resolution of 2560x1440, and supports 99% of Adobe RGB. It’s plenty big enough for photo editing.
For select NEC monitors, you should consider their SpectraView calibration software and colorimeter. It makes calibrating very easy–it’s basically hands-off one you start it.
There are certainly other makes out there with similar specs. You might also consider a 4k monitor (more expensive).
I hope others chime in with their recommendations.
