Got my Display 2 in the post this morning so did a couple of quick calibrations. First was for best grayscale tracking and returned acceptable but not great results - a high deltaE of 1.94 I redid the calibration and selected "Maximise Contrast" and the results are much more acceptable with a lower black level and more accurate colour. I did a quick calibration using only 32 steps; it's possible to do a more accurate calibration with 52 steps but I just don't have time at the moment. Also, the Display 2 is not really suitable for a wide gamut monitor like this but I got it on ebay for 99 pence so I can't really complain. These initial calibrations were done with the internal LUT... I might try the bundled Match software (or other software that will work with the Display 2) and see if I get comparable results with the graphics card LUT.
