Thanks again! What I find especially annoying with the Display Lt is the drift in luminosity (and possibly in colors) in different conditions (cold Vs. warm). After a warm-up of 30-45 minutes the measured white point luminosity changes of about 4-5% w.r.t. when it is cold! I really hope that the hw temperature compensation that is in the i1 Display Pro allows for much better results than this!
