U4021QW Color Calibration Factory Report
Every Dell U4021QW is shipped incorporating pre-tuned
Standard modes (sRGB and DCl-P3) with Color and
Luminance. Uniformity is adjusted across the screen to
meet
E2000 < 2 and 97-102% respectively. This
helps prevent signicant color inconsistencies or
inaccuracies. In addition, a tighter grey-scale tracking
on each U4021QW monitor helps enable ultrasmooth
color gradation.The factory measurement from this very
unit are shown here.
