[Matt Harris] “Can anyone comment what this does for grading in resolve?”

It allows the monitor to display a wider gamut of colors. See also this concurrent post in the FCPX Debate forum: https://forums.creativecow.net/thread/335/84692

The viewer in Resolve isn’t as accurate as a proper monitoring solution so it won’t help that much. Also I would wait until someone profiles the monitor to see how accurate it actually is.
