Aw, guess you decided to return the last Oct model you had? Can't say I blame you, the hot pixel thing would worry me. I wonder what that was about... I did check my monitor a couple of times for hot pixels on an all black screen, but didn't see any.
What's funny is, I was going to try to send you some recommended settings and ICC file, but I've spent like the last month trying to get the perfect calibration for my panel... thought I had it like two weeks ago, but then my backlight continued to drift. What's frustrating is that it doesn't seem to stabilize... starts warm (6200K), settles for a bit at a slightly more neutral temp (6350K), but then after a few hours it seems to become warmer again. It just gets plain out of whack if you leave the monitor on for several days at a time. I am not sure if other monitors do this, because I have never spent this much time messing with my previous two monitors (U3011 and PG278Q).
Anyway, for anyone else trying to calibrate their XB271HU with a ColorMunki Display or i1 Display Pro (same hardware)... you're probably better off using the software that comes with it, instead of DisplayCAL. I tested many, many different calibrations, and found that the CM Display software generally does a better job correcting the weird gamma on this panel (at least Oct build). It also does at least as well for correcting the grayscale.
