I have narrowed my choice of monitor to one of these two. The 2690WUXi2 is a new generation product. The 3090WQXi is not. I'm leaning to a 30" screen, but will not get the new color gamet offered by the new 2690. Is that a big deal?
Actually the LCD2690WUXi2 has a color gamut that is essentially the same as the LCD3090WQXi. One of the changes made with the LCD2690WUXi2 over the LCD2690WUXi was to improve the color gamut - mainly in the blue.
