The average delta E went up to 2.2 while most of the 27's competitors remained about the same. The 27-inch LED Cinema Display isn't going to be winning any awards for color reproduction but it's good enough when calibrated.Ĭuriously enough, dropping brightness down to 100 nits caused a noticeable reduction in color tracking. I found the 27-inch LED Cinema Display to be way too blue and green out of the box, calibrated the display did much better: Uncalibrated the display's color accuracy isn't very good. For all of these, dynamic contrast is disabled.
We also take an uncalibrated measurement to show performance out of the box using either the manufacturer supplied color profile, or a generic one with no LUT data. We target 6500K and a gamma of 2.2, but sometimes the best performance lies at native temperature and another gamma, so we try to find what the absolute best performance could be. We’ve deprecated the Monaco Optix XR Pro colorimeter in favor of an Xrite i1D2 since there are no longer up-to-date drivers for modern platforms.įor these tests, we calibrate the display and try to obtain the best Delta-E we can get at both 200 nits of brightness for normal use, and 100 nits for print brightness. Then the difference will no doubt be apparent.Īs I mentioned in our earlier reviews, we’ve updated our display test bench. That is, until you print or view media on another monitor. Of course, the big consideration here is frame of reference unless you have another monitor or some print samples (color checker card) to compare your display with, you probably won’t notice. Finally, Delta E of 4.0 and above is considered visible with the human eye. Moving up, a Delta E of 2.0 or less is generally considered fit for use in a professional imaging environment - it isn’t perfect, but it’s hard to gauge the difference. In practice, a Delta E under 1.0 is perfect - the chromatic sensitivity of the human eye is not great enough to distinguish a difference. The difference between the color represented by the display, and the color requested by the GPU is our Delta-E, and lower is better here. So our percentages are reported with respect to this number, and larger is generally better.Ĭolor accuracy (Delta E) refers to the display’s ability to display the correct color requested by the GPU and OS. In this case, our reference is the AdobeRGB 1998 color space, which is larger than the sRGB color space. Color gamut refers to the range of colors the display is able to represent with respect to some color space. We report two main quality metrics in our display reviews: color accuracy (Delta-E) and color gamut.
