Dell U3011 Review: Dell's New 30-inch Flagshipby Brian Klug on January 13, 2011 9:17 PM EST
Now for color consistency, we take our best calibration profile from the very center at 200 nits and test color accuracy at 9 different places around the LCD display in an evenly distributed grid. We’ve shown before that calibration is actually very localized across the display, partly due to the brightness not being uniform, partly due to the discrete nature of the LCD panel itself.
It's a bit surprising, but Delta-E actually creeps up somewhat high at the edges of the U3011. When you consider the sheer size of the display, it makes sense, but this is the highest I believe we've seen yet for change in Delta-E away from the center where we made our calibration profile.
