The measurements here were made manually using Calman measurement software from Portrait Displays (www.portrait.com) together with a Klein K-10A color meter and a Fresco Six-G test pattern generator from Murideo/AVPro.
Just prior to performing calibrations, my aging Photo Research PR-650 spectroradiometer bit the dust. My measurements are typically made with the Klein colorimeter, but since the latter is less accurate on color it must first be “profiled” against a more precise device
