A new NEC EA275UHD will soon be available at an attractive price. On paper it looks like a display for office work rather than for color critical applications, but (like all recent EAxx4WMi series displays) it can be hardware calibrated by NEC SpectraView calibration software.
Right now it's supported by NEC SpectraView II rev. 1.1.20:
It has AH-IPS type panel with W-LED (blue LED + red and green phosphor) backlight:
The blue LED, R and G phosphors are well chosen, so the display gamut is close to sRGB as well as it covers ~100% of that color space:
The native wtpt is ~6100K, and the TRC in factory modes exhibit 3-4∆E peak deviations to a TRC of γ2.2, which is typical for office desktop displays:
N mode:
sRGB mode:
...but contrary to typical office displays we can linearise TRC using internal 10bit 1DLUT and NEC SpectraView II calibration software:
