The average uniformity of black brightness is 5.1% with a maximum deflection of 12.7%. For white brightness the average and maximum are 4.8% and 15.6%, respectively. These numbers suggest that the monitor does not have conspicuous dark or bright spots. Interestingly, it is the center of the screen that is brighter on black. I usually see the opposite in my tests.
The Flatron W2284F does not have an extended color gamut. Its color gamut triangle is somewhat shifted relative to the standard sRGB space, so the monitor is worse at reproducing blues and reds (they have slight turquoise and orange hues, respectively) but better than sRGB in greens. The difference can hardly be spotted with a naked eye, though.
The monitor has too much of contrast at the default settings as is indicated by the bend of the gamma curves in the right part of the diagram. The monitor’s darks are brighter than necessary (its curves go higher than the theoretical curve) but I don’t see any serious problems.
At the reduced Brightness and Contrast settings the curves improve in the right part of the diagram, but darks are still a little bit brighter than necessary.
