1. Max brightness decreases slightly to 320 cd/m^2. This is better suited for most imaging work, and will give a slightly better contrast ratio when working at very low luminance levels.
2. Color gamut remains sRGB, but is slightly better aligned with the sRGB primaries. The sRGB coverage is 96.7% (vs 93.5% on the LCD2490WUXi) in CIE xy.
3. The panel is the latest "eH-IPS A" type. This panel does not have the A-TW polarizer used on the LCD2490WUXi. The reasons for no longer using the A-TW are the same as for the LCD2690WUXi2.
4. Contrast ratio increases to 1000:1. Note that the A-TW polarizer actually decreases the contrast ratio when looking directly at the display, so this high a contrast ratio would not be possible with the A-TW.
5. The screen is not "glossy".
6. A "-SV" bundled SpectraView II version will be available in the US. The software has already been updated to support this model. It will still be possible to make your own bundle by purchasing the software or calibration kit.
7. The warranty remains 4 year in the US.
8. All other features remain the same as the LCD2490WUXi.
