Any modern IPS has lot higher contrast than that NEC and VA isn't needed for improvement in that.I'm keeping my NEC PA271 for photo editing and as a second screen.
I'll wait for the 4k market to mature before going that way I think.
Tech would be actually mature for 4K monitors:
That even has proper contrast unlike 2560x1440 resolution panel.
It's like bean counters and marketroids aren't allowing advance and keep reselling same old.
