PA241W is much better than 2490WUXi2. The PA series is significally improved, has more features, better controls with more precision, useful Multiprofiler software etc. You need NEC Spectraview II calibration software in both cases to make automatic hardware calibration, in case of wide gamut PA241W display NEC custom matted sensor is also recommended (SVII kit).
If you want normal gamut display, consider PA231W or wait for new P241W (same as PA241W, but with normal gamut panel+backlight)
