The NEC is also a nice monitor (fine reviews).
I just went for the BenQ SW271C as 27" is a fine size for me. It will be an upgrade from my HP 2509m monitor.
I wonder if my very old Xrite i1 Eye-One Display2 can still work to calibrate the new monitor......and if I can download the software for from Xrite.com......we will see.
I also looked at Eizo monitors but seems to be a "price-jump" up for a 4k, 27" monitor. They are probably good also.....but I am sure the BenQ will be "good enough" for my purpose.
It is also part of a "home office" solution.....
